All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Furthermore, the term "include" and any variations thereof is intended to cover non-exclusive protection. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus. The term "plurality" in the present invention may mean at least two, for example, two, three or more, and embodiments of the present invention are not limited.

Referring to fig. 1, fig. 1 is a schematic diagram of an application environment provided by an embodiment of the present invention, where the schematic diagram includes a shared hard disk expansion cabinet 100 and a storage server 200, and the shared hard disk expansion cabinet 100 and the storage server 200 are connected by a physical link. After receiving the access request uploaded by the shared hard disk expansion cabinet 100, the storage server 200 may perform a nanotube on the access request, perform an attribution configuration on the managed shared hard disk expansion cabinet 100, and finally generate indication information of successful configuration when the first type case is satisfied between the shared hard disk expansion cabinet and the attribution group.

Specifically, after the storage server 200 obtains the access request initiated by the shared hard disk expansion cabinet 100. Then, the storage server 200 may perform nanotubes on the shared hard disk expansion cabinet that initiates the access request, and perform home configuration on the shared hard disk expansion cabinet 100 after the nanotubes, so as to obtain a home group of the shared hard disk expansion cabinet, and finally generate indication information that the configuration is successful when the first type case is satisfied between the shared hard disk expansion cabinet and the home group. The indication information of successful configuration is used for indicating that partial case reminding exists but service issuing can be performed.

In this embodiment of the present application, the home configuration of the shared hard disk expansion cabinet of the nanotube may be the storage server 200 shown in fig. 1, or may be other computer terminals having the same function as the storage server, or similar computing devices. Further, the storage server 200 may be replaced with a server system, an operation platform, or a server cluster including a plurality of servers.

According to an embodiment of the present invention, there is provided a storage cluster management method embodiment, it being noted that the steps shown in the flowchart of the figures may be performed in a computer system, such as a set of computer executable instructions, and, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order other than that shown or described herein.

In this embodiment, a storage cluster management and control method is provided, which may be used for the shared hard disk expansion cabinet described above, and fig. 2 is a flowchart of a storage cluster management and control method according to an embodiment of the present invention, as shown in fig. 2, where the flowchart includes the following steps:

step S201, carrying out attribution configuration on the shared hard disk expansion cabinet of the nano tube to obtain an attribution group of the shared hard disk expansion cabinet.

In this embodiment, when an access request initiated by a shared hard disk expansion cabinet is received, the shared hard disk expansion cabinet is managed, and the shared hard disk expansion cabinet of the management is allocated in a home mode, so as to obtain a home group of the shared hard disk expansion cabinet, and a necessary condition is provided for subsequent management and control of the shared hard disk expansion cabinet. The shared hard disk expansion cabinet is a hard disk expansion cabinet for expanding the node communication path of the expansion cabinet.

The hard disk expansion cabinet is expansion equipment externally connected with the storage server, and can directly provide extra data storage space for the storage server. At present, one hard disk expansion cabinet contains two expansion cabinet nodes to form a redundant structure, and each expansion cabinet node can only carry out communication of a physical link and bottom signal processing and has no calculation function, namely, no equipment such as a CPU, a memory, a system hard disk and the like. Each expansion cabinet node comprises two groups of external interfaces, wherein one group is an Input (IN) port and is used for connecting an Output (OUT) port of a storage node; the other group is an OUT port which is used for being connected with an IN port of the next-stage hard disk expansion cabinet. Each centralized storage server contains two storage nodes, each storage node can be regarded as a computer, and a plurality of OUT ports can be expanded through an external card. Therefore, when one centralized storage device is abnormally inoperable, the hard disk expansion cabinet connected to the centralized storage device is invisible in the storage cluster and becomes an offline state, the data stored on the corresponding hard disk expansion cabinet cannot be used by a user, and the reliability of the storage cluster is reduced. The home group of the shared hard disk expansion cabinet is an attribute of a storage cluster, and usually two storage devices with the same home group cannot exist in the same storage cluster.

IN an alternative implementation manner, an IN port is added IN an expansion cabinet node of a hard disk expansion cabinet with an IN port and an OUT port respectively, so that two groups of IN ports and one group of OUT ports exist on a single hard disk expansion cabinet. Then creating a physical connection channel for the additionally added group of IN ports and the bottom management chip of the main board, so that the group of IN ports can normally perform data communication; the model identification (such as shared hard disk expansion cabinet) of the hard disk expansion cabinet after the IN port is changed is used for distinguishing the hard disk expansion cabinet from the common hard disk expansion cabinet. At this time, after the storage cluster detects the hard disk expansion cabinet with access, the identification of the hard disk expansion cabinet model is checked, whether the storage cluster is a common hard disk expansion cabinet or a shared hard disk expansion cabinet is judged, if the storage cluster is detected as the common hard disk expansion cabinet, the original management and control logic is still used for managing and controlling, and if the storage cluster is detected as the shared hard disk expansion cabinet, the shared hard disk expansion cabinet of the nano tube is subjected to attribution configuration, namely, storage nodes of the storage cluster to which the shared hard disk expansion cabinet of the nano tube belongs are grouped, so that an attribution group of the shared hard disk expansion cabinet is obtained. It can be understood that adding an IN port IN the expansion cabinet node is only an example, and the number of newly added IN ports or the data of newly added OUT ports can be adjusted according to the actual application requirements.

Step S202, when the first type case is satisfied between the shared hard disk expansion cabinet and the home group, generating indication information of successful configuration.

In this embodiment, after the home configuration is performed on the managed shared hard disk expansion cabinet to obtain the home group of the shared hard disk expansion cabinet, the storage trunking communication participated by the shared hard disk expansion cabinet may be managed and controlled, and when the first type case is satisfied between the shared hard disk expansion cabinet and the home group, the indication information of successful configuration is generated. The indication information of successful configuration is used for indicating that partial case reminding exists but service issuing can be performed. That is, in this embodiment, when a part of case alert exists between the shared hard disk expansion cabinet and the home group (for example, when the connection between the shared hard disk expansion cabinet and the storage node in the home group is incomplete and the case alert is triggered), the service can still be issued, so that the situation that when one centralized storage device fails to work abnormally, the hard disk expansion cabinet connected to the centralized storage device is also invisible in the storage cluster and becomes an offline state, and the data stored in the hard disk expansion cabinet cannot be used by a user, and the reliability of the storage cluster is reduced can be avoided.

Optionally, the first type of case satisfied between the shared hard disk expansion cabinet and the home group may be that all storage nodes in the home group are connected to the shared hard disk expansion cabinet, and/or when a part of storage nodes in the home group are connected to the shared hard disk expansion cabinet and the connection number of a part of storage nodes and the shared hard disk expansion cabinet is greater than or equal to a threshold value. That is, the shared hard disk expansion cabinet is in an online state, and all storage nodes connected with the shared hard disk expansion cabinet can communicate with the shared hard disk expansion cabinet, so that the shared hard disk expansion cabinet and the attribution group are judged to meet the first type of case; and/or the part of the storage nodes connected with the shared hard disk expansion cabinet can communicate with the shared hard disk expansion cabinet, and the connection number of the part of the storage nodes connected with the shared hard disk expansion cabinet is greater than or equal to a threshold value, and at the moment, the situation that the shared hard disk expansion cabinet and the attribution group meet the first type of cases is judged. The threshold is the number of connections meeting the communication requirement, and can be adjusted according to actual requirements.

According to the storage cluster management and control method provided by the embodiment, the home configuration is carried out on the shared hard disk expansion cabinet of the nano-tube to obtain the home group of the shared hard disk expansion cabinet, the shared hard disk expansion cabinet is a hard disk expansion cabinet for expanding the node communication path of the expansion cabinet, and a necessary condition is provided for the follow-up management and control of the shared hard disk expansion cabinet; when the first type of case is met between the shared hard disk expansion cabinet and the attribution group, generating indication information which is configured successfully, wherein the indication information which is configured successfully is used for indicating that part of case reminding exists but service issuing can be performed, so that the situation that in a storage cluster, when one centralized storage device is abnormally unavailable, the hard disk expansion cabinet connected to the centralized storage device is also invisible in the storage cluster and becomes an offline state, and the data stored on the hard disk expansion cabinet is unavailable to a user correspondingly, and the reliability of the storage cluster is reduced is avoided; the shared hard disk expansion cabinet can be used for improving the reliability and the disk space utilization rate of the centralized storage cluster in a non-dual-activity environment.

In this embodiment, a storage cluster management and control method is provided, which may be used for the shared hard disk expansion cabinet described above, and fig. 3 is a flowchart of a storage cluster management and control method according to an embodiment of the present invention, as shown in fig. 3, where the flowchart includes the following steps:

Step S301, carrying out attribution configuration on the shared hard disk expansion cabinet of the nano tube to obtain an attribution group of the shared hard disk expansion cabinet.

Please refer to step S201 in the embodiment shown in fig. 2 in detail, which is not described herein.

Step S302, when the first type case is satisfied between the shared hard disk expansion cabinet and the home group, generating indication information of successful configuration.

Specifically, the step S302 includes:

step S3021, obtaining the connection numbers of all storage nodes in the home group and the shared hard disk expansion cabinet.

In this embodiment, the number of connections between the storage node and the shared hard disk expansion cabinet in the home group is obtained to determine whether the shared hard disk expansion cabinet and the home group satisfy the first type case.

In step S3022, when all storage nodes in the home group are connected to the shared hard disk expansion cabinet, it is determined that the shared hard disk expansion cabinet and the home group satisfy the first type case.

In this embodiment, when all storage nodes in the home group are connected to the shared hard disk expansion cabinet, that is, the shared hard disk expansion cabinet is in an online state and can perform normal communication, it is determined that the shared hard disk expansion cabinet and the home group satisfy the first type case.

Taking a communication path between two shared hard disk expansion cabinets (a first shared hard disk expansion cabinet and a second shared hard disk expansion cabinet) and a storage four-control cluster as an example, wherein each shared hard disk expansion cabinet is a hard disk expansion cabinet with two groups of IN ports and one group of OUT ports, and storage nodes of the storage four-control cluster are divided into two attribution groups (a first attribution group and a second attribution group, and the first attribution group and the second attribution group comprise two storage nodes such as a first storage node and a second storage node); the first expansion cabinet node and the second expansion cabinet node of the first shared hard disk expansion cabinet and the second shared hard disk expansion cabinet respectively comprise two IN ports and an OUT port, and each of the two OUT ports of each storage node IN the first attribution group and the second attribution group is respectively connected with one IN port IN each expansion cabinet node IN the first shared hard disk expansion cabinet and the second shared hard disk expansion cabinet. The 4 IN ports of each shared hard disk expansion cabinet are therefore normally connected to and communicate with 4 storage nodes. At this time, there is a first communication environment Case1, case1: when 4 storage nodes can see the shared hard disk expansion cabinet, the state of the shared hard disk expansion cabinet is judged to be online, at the moment, the command for configuring the shared hard disk expansion cabinet attribution group can be normally executed, error reporting information is avoided, and the shared hard disk expansion cabinet attribution group can be seen to be successfully set by checking the command.

It can be understood that the communication paths between the two shared hard disk expansion cabinets and the storage four-control cluster are only examples, and can be adjusted according to actual requirements.

In step S3023, when part of the storage nodes in the angel group are connected to the shared hard disk expansion cabinet and the connection number of the part of the storage nodes and the shared hard disk expansion cabinet is greater than or equal to a threshold value, it is determined that the shared hard disk expansion cabinet and the attribution group satisfy the first type case.

In this embodiment, only a part of storage nodes in the home group may be connected to the shared hard disk expansion cabinet, and when the number of connections between a part of storage nodes and the shared hard disk expansion cabinet is greater than or equal to a threshold, it is determined that the first type case is satisfied between the shared hard disk expansion cabinet and the home group. The threshold is the number of connections meeting the communication requirement, and can be adjusted according to actual requirements.

For example, the description is based on the above examples:

second communication environment Case2, case2: when 3 storage nodes can see the shared hard disk expansion cabinet, the state of the shared hard disk expansion cabinet is judged to be degraded, the storage cluster management interface has an alarm to prompt that the current link of the shared hard disk expansion cabinet is abnormal, and when a command for configuring the attribution group of the shared hard disk expansion cabinet is executed at the moment, if the configured attribution group is the attribution group of which both the two storage nodes can see the shared hard disk expansion cabinet, the command can be normally executed, and meanwhile, the command is prompted to indicate that the storage nodes in the other attribution group xxx are not completely connected with the shared hard disk expansion cabinet, and the fault exists and needs to be removed as soon as possible, and the successful configuration of the attribution group of the shared hard disk expansion cabinet can be seen through checking the command.

Third communication environment Case3, case3: when 3 storage nodes can see the shared hard disk expansion cabinet, the state of the shared hard disk expansion cabinet is judged to be degraded, the storage cluster management interface has an alarm to prompt that the current link of the shared hard disk expansion cabinet is abnormal, and when a command for configuring the attribution group of the shared hard disk expansion cabinet is executed at the moment, if the configured attribution group is a attribution group which can be seen by one storage node, the command can be normally executed, and simultaneously prompts that 'the connection between the storage node in the current attribution group xxx and the shared hard disk expansion cabinet is incomplete, the fault exists, the connection between the storage node in the current attribution group xxx and the shared hard disk expansion cabinet needs to be removed as soon as possible, and the connection between the storage node in the other attribution group xxx and the shared hard disk expansion cabinet is complete and the priority use is recommended', and the successful configuration of the attribution group of the shared hard disk expansion cabinet can be seen through checking the command.

Fourth communication environment Case4, case4: when 2 storage nodes can see the shared hard disk expansion cabinet and the two storage nodes are in the same attribution group, the state of the shared hard disk expansion cabinet is judged to be degraded, a storage cluster management interface gives an alarm to prompt that the current link of the shared hard disk expansion cabinet is abnormal, and when a command for configuring the attribution group of the shared hard disk expansion cabinet is executed at the moment, if the configured attribution group is the attribution group of the shared hard disk expansion cabinet which can be seen by the two storage nodes, the command can be normally executed, meanwhile, the fact that the connection between the storage nodes in the other attribution group xxx and the shared hard disk expansion cabinet is incomplete, faults exist and need to be eliminated as soon as possible is prompted, and the success configuration of the attribution group of the shared hard disk expansion cabinet can be seen by checking the command.

Sixth communication environment Case6, case6: when 2 storage nodes can see the shared hard disk expansion cabinet and the two storage nodes are in different attribution groups, the state of the shared hard disk expansion cabinet is judged to be degraded, a storage cluster management interface gives an alarm to prompt that the current shared hard disk expansion cabinet link is abnormal, and when a command for configuring the attribution group of the shared hard disk expansion cabinet is executed at the moment, the command can be normally executed, and simultaneously prompts that 'the connection between the storage nodes in all the current attribution groups and the shared hard disk expansion cabinet is incomplete, faults exist and the fault is suggested to be eliminated as soon as possible', and the successful setting of the attribution group of the shared hard disk expansion cabinet can be seen through checking the command.

Seventh communication environment Case7, case7: when only 1 storage node can see the shared hard disk expansion cabinet, the state of the shared hard disk expansion cabinet is judged to be degraded, the storage cluster management interface can give an alarm to prompt that the current link of the shared hard disk expansion cabinet is abnormal, and when a command for configuring the attribution group of the shared hard disk expansion cabinet is executed at the moment, if the attribution group is the attribution group of which the storage node can see the shared hard disk expansion cabinet, the command can be normally executed, and meanwhile, the command is prompted to indicate that the connection between the storage node and the shared hard disk expansion cabinet in the current attribution group xxx is incomplete, has a fault and needs to be removed as soon as possible, and the successful setting of the attribution group of the shared hard disk expansion cabinet can be seen through checking the command.

In general, when the number of connections between the storage nodes and the shared hard disk expansion cabinet is greater than or equal to a threshold, there is a situation that, for example, the storage nodes in one of the two home groups can be normally configured to communicate, and the storage nodes in the other home group have incomplete connection; or a situation in which the storage nodes in each of the two home groups are not fully connected, but are normally configurable for communication.

Therefore, in this embodiment, when a part of storage nodes connected with the shared hard disk expansion cabinet can communicate with the shared hard disk expansion cabinet, and the connection number of the part of storage nodes connected with the shared hard disk expansion cabinet is greater than or equal to a threshold, it is determined that a part of case reminding exists between the shared hard disk expansion cabinet and the home group, service delivery can still be performed; therefore, the situation that in the storage cluster, after one piece of centralized storage equipment is abnormal and cannot work, the hard disk expansion cabinet connected to the storage cluster is invisible in the storage cluster and becomes an offline state, and the corresponding data stored on the hard disk expansion cabinet cannot be used by a user, so that the reliability of the storage cluster is reduced is avoided.

Step S303, when the connection of the storage nodes connected with the shared hard disk expansion cabinet is abnormal or the connection number is smaller than the threshold value, switching the attribution group of the shared hard disk expansion cabinet to another attribution group.

In this embodiment, when the connection abnormality or the connection number of the storage nodes connected to the shared hard disk expansion cabinet is smaller than the threshold, the home group of the shared hard disk expansion cabinet is switched to another home group, so as to perform normal service delivery.

And step S304, when all the storage nodes in the attribution group connected with the shared hard disk expansion cabinet are restored to be connected, or the connection number is larger than or equal to a threshold value, switching the shared hard disk expansion cabinet from another attribution group to an attribution group.

In this embodiment, when all the storage nodes in the home group connected to the shared hard disk expansion cabinet resume connection or the connection number is greater than or equal to the threshold, the shared hard disk expansion cabinet is switched from another home group to the home group, so as to issue the service.

For example, the following description is given based on the example in step S302:

after the configuration of the home group of the shared hard disk expansion cabinet is finished, if the environment information accords with the conditions described in Case1, case2, case3 or Case6, assuming that the home group is 0, and the other home group is 1, the management and control and data service of the home group are issued from the home group 0 preferentially, and the data service received on the storage node of the home group 1 is transferred to the storage node of the shared hard disk expansion cabinet home group 0 for data service issuing; simultaneously, an OUT port on a storage node can regularly send heartbeat detection signals to check the states of a link and an IN port IN an expansion cabinet node, when a storage cluster detects that all physical links between a home group 0 and a shared hard disk expansion cabinet are abnormal, corresponding alarm information is prompted on a management interface of the storage cluster, the home group of the shared hard disk expansion cabinet is temporarily changed into a home group 1, at the moment, data service is transferred to the storage node of the home group 1 for issuing, after the abnormality is removed, the link is recovered to be normal, the storage cluster can change the home group of the shared hard disk expansion cabinet back to the home group 0; if the storage cluster detects that the physical link between the home group 1 and the shared hard disk expansion cabinet is abnormal, the corresponding alarm information is only prompted at the management interface of the storage cluster, the home group of the shared hard disk expansion cabinet is not changed, and the data service is still issued from the home group 0.

It can be seen that, the priority of the current home group is greater than the priority of another home group, the service is issued from the storage nodes in the home group with highest priority, only when part of the storage nodes in the home group with high priority are all connected abnormally or the connection number is smaller than the threshold value, that is, the normal issuing of the service cannot be performed, the service is switched to the home group with second priority, the storage nodes in the home group with highest priority still can be switched back to perform the service issuing after the home group with highest priority returns to normal, and when the physical link between the storage nodes in the home group with second priority and the shared hard disk expansion cabinet is abnormal, the corresponding alarm information is prompted only in the management interface of the storage cluster, the home group of the shared hard disk expansion cabinet is not changed, and the data service is still issued from the home group with highest priority.

Step S305, when there is a connection failure of some storage nodes in the home group connected to the shared hard disk expansion cabinet, adding a storage node to which the home group resumes connection, and/or resuming connection of another home group to the shared hard disk expansion cabinet.

The connection fault is used for representing that no storage node is connected to the shared hard disk expansion cabinet, or the connection number of the rest storage nodes and the shared hard disk expansion cabinet is smaller than a threshold value.

For example, the following description is given based on the example in step S302:

if the environment information accords with the conditions described in Case4 or Case7, assuming that the attribution group is 0, the other group is 1, controlling and controlling data service aiming at the environment information can be issued from the attribution group 0 only, and at the moment, the storage cluster management interface has the information such as the connection of the currently shared hard disk expansion cabinet with a single attribution group, reliability loss and the like, and at the moment, if the storage nodes in the attribution group 0 are all disconnected with the nodes of the shared hard disk expansion cabinet, the storage cluster cannot change the attribution group of the shared hard disk expansion cabinet, and the user side shows that the service is interrupted in progress; when the storage cluster detects that at least one storage node is in recovery connection with a node of the shared hard disk expansion cabinet, if the storage node in the recovery connection contains a storage node in the attribution group 0, the shared hard disk expansion cabinet is in recovery connection with the storage cluster, data read-write service is provided for the shared hard disk expansion cabinet, if the storage node in the recovery connection does not contain the storage node in the attribution group 0, the storage cluster changes the attribution group 0 of the shared hard disk expansion cabinet into the attribution group 1, so that the shared hard disk expansion cabinet is in recovery connection with the storage cluster, and data read-write service is continuously provided for the storage cluster.

According to the storage cluster management and control method provided by the embodiment, the home configuration is carried out on the shared hard disk expansion cabinet of the nano-tube to obtain the home group of the shared hard disk expansion cabinet, the shared hard disk expansion cabinet is a hard disk expansion cabinet for expanding the node communication path of the expansion cabinet, and a necessary condition is provided for the follow-up management and control of the shared hard disk expansion cabinet; when the first type of case is met between the shared hard disk expansion cabinet and the attribution group, generating indication information which is configured successfully, wherein the indication information which is configured successfully is used for indicating that part of case reminding exists but service issuing can be performed, so that the situation that in a storage cluster, when one centralized storage device is abnormally unavailable, the hard disk expansion cabinet connected to the centralized storage device is also invisible in the storage cluster and becomes an offline state, and the data stored on the hard disk expansion cabinet is unavailable to a user correspondingly, and the reliability of the storage cluster is reduced is avoided; the shared hard disk expansion cabinet can be used for improving the reliability and the disk space utilization rate of the centralized storage cluster in a non-dual-activity environment. When the connection abnormality or the connection number of part of storage nodes connected with the shared hard disk expansion cabinet is smaller than the threshold value, the attribution group of the shared hard disk expansion cabinet is switched to another attribution group, and when the connection restoration or the connection number of part of storage nodes in the attribution group connected with the shared hard disk expansion cabinet is larger than or equal to the threshold value, the shared hard disk expansion cabinet is switched to the attribution group from the other attribution group so as to ensure the normal issuing of the storage cluster service. When a connection fault exists in part of storage nodes in the attribution group connected with the shared hard disk expansion cabinet, the storage nodes in the attribution group for recovering the connection and/or the connection between the other attribution group and the shared hard disk expansion cabinet are added, so that the reliability and the disk space utilization rate of the centralized storage cluster are improved.

In this embodiment, a storage cluster management and control method is provided, which may be used for the shared hard disk expansion cabinet described above, and fig. 4 is a flowchart of a storage cluster management and control method according to an embodiment of the present invention, as shown in fig. 4, where the flowchart includes the following steps:

step S401, carrying out attribution configuration on the shared hard disk expansion cabinet of the nano tube to obtain an attribution group of the shared hard disk expansion cabinet.

Please refer to step S201 in the embodiment shown in fig. 2 in detail, which is not described herein.

Step S402, when the shared hard disk expansion cabinet and the attribution group meet the first type of case, generating indication information of successful configuration.

Please refer to step S302 in the embodiment shown in fig. 3 in detail, which is not described herein.

Step S403, when the shared hard disk expansion cabinet and the attribution group meet the second type of case, generating indication information of configuration failure.

In this embodiment, after the home configuration is performed on the managed shared hard disk expansion cabinet to obtain the home group of the shared hard disk expansion cabinet, the storage trunking communication participated by the shared hard disk expansion cabinet may be managed and controlled, and when the second type case is satisfied between the shared hard disk expansion cabinet and the home group, the indication information of the configuration failure is generated. The configuration failure indication information is used for indicating the configuration failure of the home group of the shared hard disk expansion cabinet. Namely, the configuration between the shared hard disk expansion cabinet and the home group in the embodiment fails, and data communication and corresponding service delivery cannot be performed.

In an alternative embodiment, when a part of storage nodes in the angel group are connected to the shared hard disk expansion cabinet and the connection number of the part of storage nodes and the shared hard disk expansion cabinet is smaller than a threshold value, it is determined that the second type of case is satisfied between the shared hard disk expansion cabinet and the attribution group.

For example, the following description is given based on the example in step S302:

fifth communication environment Case5, case5: when 2 storage nodes can see the shared hard disk expansion cabinet and the two storage nodes are in the same attribution group, the state of the shared hard disk expansion cabinet is judged to be degraded, a storage cluster management interface gives an alarm to prompt that the current link of the shared hard disk expansion cabinet is abnormal, and when a command for configuring the attribution group of the shared hard disk expansion cabinet is executed at the moment, if the configured attribution group is that the two storage nodes cannot see the attribution group of the shared hard disk expansion cabinet, the command cannot be executed, and meanwhile, the command is prompted to indicate that 'the selected attribution group xxx is not connected with the shared hard disk expansion cabinet', and the configuration failure of the attribution group of the shared hard disk expansion cabinet can be seen through checking the command.

Eighth communication environment Case8, case8: when only 1 storage node can see the shared hard disk expansion cabinet, judging that the state of the shared hard disk expansion cabinet is degraded, and when a command for configuring the home group of the shared hard disk expansion cabinet is executed at the moment, if the configured home group is zero storage nodes and can see the home group of the shared hard disk expansion cabinet, the command cannot be executed, and meanwhile, the command is prompted to 'no connection with the shared hard disk expansion cabinet in the selected home group xxx', and the configuration failure of the home group of the shared hard disk expansion cabinet can be seen through checking the command.

According to the storage cluster management and control method provided by the embodiment, after the home configuration is carried out on the shared hard disk expansion cabinet of the nano-tube to obtain the home group of the shared hard disk expansion cabinet, the storage cluster communication participated by the shared hard disk expansion cabinet can be managed and controlled, and when the first type of case is met between the shared hard disk expansion cabinet and the home group, the indication information of successful configuration is generated. The indication information of successful configuration is used for indicating that partial case reminding exists but service issuing can be performed. In other words, in the storage cluster, when a part of case reminding exists between the shared hard disk expansion cabinet and the home group, service delivery can still be performed, so that the situation that when one centralized storage device is abnormally unavailable in the storage cluster, the hard disk expansion cabinet connected to the centralized storage device is also invisible in the storage cluster and becomes an offline state, and the data stored on the hard disk expansion cabinet is unavailable to a user correspondingly, and the reliability of the storage cluster is reduced is avoided. When part of storage nodes in the attribution group are connected to the shared hard disk expansion cabinet and the connection number of part of storage nodes and the shared hard disk expansion cabinet is smaller than a threshold value, determining that the shared hard disk expansion cabinet and the attribution group meet the second type of cases, and generating indication information of configuration failure when the shared hard disk expansion cabinet and the attribution group meet the second type of cases so as to remind a user whether to carry out attribution configuration of the shared hard disk expansion cabinet again.

In this embodiment, a storage cluster management and control method is provided, which may be used for the shared hard disk expansion cabinet described above, and fig. 5 is a flowchart of a storage cluster management and control method according to an embodiment of the present invention, as shown in fig. 5, where the flowchart includes the following steps:

step S501, carrying out attribution configuration on the shared hard disk expansion cabinet of the nano tube to obtain an attribution group of the shared hard disk expansion cabinet.

Please refer to step S201 in the embodiment shown in fig. 2 in detail, which is not described herein.

Step S502, when the shared hard disk expansion cabinet and the attribution group meet the first type of case, generating indication information of successful configuration.

Please refer to step S302 in the embodiment shown in fig. 3 in detail, which is not described herein.

Step S503, when the shared hard disk expansion cabinet and the attribution group meet the second type of case, generating indication information of configuration failure.

Please refer to step S505 in the embodiment shown in fig. 4 in detail, which is not described herein.

Step S504, when the shared hard disk expansion cabinet is in an idle state, storing the data in the shared hard disk expansion cabinet.

In this embodiment, when the shared hard disk expansion cabinet is in an idle state, the data in the shared hard disk expansion cabinet is stored, so as to avoid the loss or reset of useful data in the shared hard disk expansion cabinet when the shared hard disk expansion cabinet is not used any more.

And step S505, deleting all information of the shared hard disk expansion cabinet of the nano tube, and removing the nano tube of the shared hard disk expansion cabinet.

In this embodiment, by deleting all the information of the shared hard disk expansion cabinet of the nanotube, the resources of each storage node of the storage cluster are released; the shared hard disk expansion cabinet is relieved, so that occupation of the shared hard disk expansion cabinet is relieved when the shared hard disk expansion cabinet is not used, and reliability of a storage cluster and disk space utilization are improved.

Step S506, when the connection between the shared hard disk expansion cabinet of the nano tube and each storage node in the attribution group still exists, the state of the shared hard disk expansion cabinet is set to be in a waiting state.

In this embodiment, when the connection between the shared hard disk expansion cabinet and each storage node in the home group still exists, the state of the shared hard disk expansion cabinet is set to be in a standby state, so that the subsequent nanotubes can be conveniently or the nanotubes can be conveniently released.

And S507, when the connection between the shared hard disk expansion cabinet of the nano tube and each storage node in the attribution group is disconnected, setting the state of the shared hard disk expansion cabinet to be an invisible state.

In this embodiment, when the connection between the shared hard disk expansion cabinet and each storage node in the home group is disconnected, the state of the shared hard disk expansion cabinet is set to be an invisible state, so as to avoid an error caused by a failure of the storage cluster to perform the nanotubes on the visible storage nodes.

In an alternative implementation manner, when the storage cluster does not use the shared hard disk expansion cabinet any more, the storage cluster management system needs to store the useful data in the shared hard disk expansion cabinet, delete the volumes, the RAIDs and the pools related to the shared hard disk expansion cabinet on the storage cluster management system, and finally execute the instruction of unmanaging, if the storage cluster management system detects that the volumes, the RAIDs or the pools related to the shared hard disk expansion cabinet still exist, the unmanaging instruction cannot be executed, and prompt an operator to check the resource information again; after management is successfully removed, if the connection lines between the shared hard disk expansion cabinet and each storage node still exist, the hard disk expansion cabinet is visible on a storage group management system in a to-be-managed mode, cannot be subjected to service operation, and can only be subjected to service operation after the home group is newly managed and set; if the connection between the shared hard disk expansion cabinet and each storage node is removed, the shared hard disk expansion cabinet is not visible on the storage cluster management system.

According to the storage cluster management and control method provided by the embodiment, after the home configuration is carried out on the shared hard disk expansion cabinet of the nano-tube to obtain the home group of the shared hard disk expansion cabinet, the storage cluster communication participated by the shared hard disk expansion cabinet can be managed and controlled, and when the first type of case is met between the shared hard disk expansion cabinet and the home group, the indication information of successful configuration is generated. The indication information of successful configuration is used for indicating that partial case reminding exists but service issuing can be performed. In other words, in the storage cluster, when a part of case reminding exists between the shared hard disk expansion cabinet and the home group, service delivery can still be performed, so that the situation that when one centralized storage device is abnormally unavailable in the storage cluster, the hard disk expansion cabinet connected to the centralized storage device is also invisible in the storage cluster and becomes an offline state, and the data stored on the hard disk expansion cabinet is unavailable to a user correspondingly, and the reliability of the storage cluster is reduced is avoided. When part of storage nodes in the attribution group are connected to the shared hard disk expansion cabinet and the connection number of part of storage nodes and the shared hard disk expansion cabinet is smaller than a threshold value, determining that the shared hard disk expansion cabinet and the attribution group meet the second type of cases, and generating indication information of configuration failure when the shared hard disk expansion cabinet and the attribution group meet the second type of cases so as to remind a user whether to carry out attribution configuration of the shared hard disk expansion cabinet again. When the shared hard disk expansion cabinet is in an idle state, the data in the shared hard disk expansion cabinet is stored, so that the loss or reset of useful data in the shared hard disk expansion cabinet is avoided when the shared hard disk expansion cabinet is not used any more. Deleting all information of the shared hard disk expansion cabinet of the nano tube to release resources of each storage node of the storage cluster; the shared hard disk expansion cabinet is relieved, so that occupation of the shared hard disk expansion cabinet is relieved when the shared hard disk expansion cabinet is not used, and reliability of a storage cluster and disk space utilization are improved. When the connection between the shared hard disk expansion cabinet and each storage node in the attribution group still exists, the state of the shared hard disk expansion cabinet is set to be in a waiting state so as to facilitate the subsequent nano-tube or release the nano-tube. When the connection between the shared hard disk expansion cabinet and each storage node in the attribution group is disconnected, the state of the shared hard disk expansion cabinet is set to be an invisible state, so that errors caused by the failure of the nanotubes when the storage cluster performs the nanotubes on the visible storage nodes are avoided.
