The present invention relates to the field of distributed storage technologies, and in particular, to a management method, a management system, a management device, and a storage medium for a distributed storage system.
Background
NAS (Network Attached Storage) literally means a device connected to a Network and having a data Storage function, and is also called a "Network Storage", which is a dedicated data Storage server, and uses data as a center to completely separate Storage devices from the server and centrally manage the data, thereby releasing bandwidth, improving performance, reducing total ownership cost, protecting investment, and having a cost far lower than that of using a conventional server for data Storage and a efficiency far higher than that of the conventional server.
In practical applications, in a NAS application scenario of medium or large scale, there are usually multiple NAS servers, and these servers may be from different vendors. When performing daily management work, NAS administrators are very inefficient and prone to errors if they log in the management interface of each NAS server to perform the management work. The MMC (Microsoft Management Console) is a Management platform, and can provide a unified and normative Management interface and an operation platform for an administrator, that is, the NAS administrator can uniformly manage the NAS servers by using the MMC.
Currently, when a NAS administrator connects a distributed storage system through an MMC, operations such as creating a share, deleting a share, and the like are performed on the MMC, and these operations can only be effective on a single storage node to which the MMC is connected. In an actual using process, due to the situations of network failure, node server failure and the like, after a node connected to the MMC fails, the MMC needs to replace other storage nodes for connection, and for operations such as creating sharing, deleting sharing and the like which are previously performed on the failed node, an administrator needs to perform the operations again on a new node connected to the MMC.
To sum up, how to more effectively manage the distributed storage system is a technical problem that those skilled in the art are urgently required to solve, and after a node connected to the MMC fails, an operation executed before can be conveniently and effectively recovered on a new node connected to the MMC.

Detailed Description
The core of the invention is to provide a management method of a distributed storage system, which can effectively manage the distributed storage system and can conveniently and effectively recover the previously executed operation on a new node connected with an MMC after the node connected with the MMC has a fault.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It should be apparent that the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating an implementation of a management method of a distributed storage system according to the present invention, where the management method of the distributed storage system can be applied to an MMC, and includes the following steps:
step S101: and setting a virtual IP for the distributed storage system, and connecting the distributed storage system through the virtual IP.
Specifically, it is considered that the purpose of the present application is to automatically resume operations executed before on a new node connected to the MMC after a node connected to the MMC fails, so that after the node connected to the MMC fails, switching of the node should be automatically performed to improve the execution efficiency of the scheme and reduce the workload of related workers. In order to effectively perform automatic switching of nodes in subsequent steps, the nodes are connected by using the virtual IP. And setting a virtual IP for the distributed storage system, and connecting the distributed storage system through the virtual IP.
In a specific embodiment of the present invention, the setting of a virtual IP for a distributed storage system described in step S101 may specifically include:
virtual IP is set for the distributed storage system through the CTDB service.
In this embodiment, considering that in the current distributed storage system, a CTDB (Cluster Trivial Database) service is usually disposed on each node, and the CTDB may support Cluster implementation using databases such as Samba, NFS, HTTPD, ISCSI, WINBIND, and the like, and may provide a Cluster function on the top level of the file system of the Cluster, manage node members, perform recovery/failover, IP reallocation, and monitor the state of the management service. Therefore, in such an embodiment, the virtual IP can be conveniently and efficiently provided through the CTDB service, that is, the virtual IP can be conveniently set for the distributed storage system through the CTDB service.
Of course, in other embodiments, other manners besides the CTDB service may be adopted as long as the virtual IP can be effectively set for the distributed storage system, so that the MMC is connected to the distributed storage system through the virtual IP, and the implementation of the present invention is not affected.
Step S102: when an operation for the distributed storage system is performed on the connected node, the operation information is saved in a configuration file.
When an operation for the distributed storage system is performed on a connected node, the operation information needs to be saved in a configuration file.
For example, in a specific embodiment of the present invention, the performing the operation on the connected node in step S102 for the distributed storage system may specifically include:
a share creation operation, a share deletion operation, or a share configuration operation for the distributed storage system is performed on the connected nodes.
The operation of the share creation means data sharing for the distributed storage system, and it is understood that information such as specific shared data content, user level permitted to access the shared data, and the like may be set when the share creation operation is performed. And the shared deletion operation means that the created shared is deleted. The sharing configuration operation means that the configuration is adjusted for the created share, for example, the adjustment of the user level allowed to access the share is performed in a specific occasion, for example, the user access of any level is allowed before the adjustment, and only the high-level user is allowed to access after the adjustment.
Of course, in other specific embodiments, besides the share creation operation, the share deletion operation, and the share configuration operation, other types of operations for the distributed storage system may be executed on the connected nodes, and the operations may be set and selected according to actual needs, without affecting the implementation of the present invention.
When an operation for the distributed storage system is performed on a connected node, operation information needs to be saved in a configuration file, that is, each time an operation is performed, an update of the configuration file needs to be performed. For example, in a case where a share creation operation for the distributed storage system is performed on a connected node, for example, a share a is created, after the share a is created, the operation needs to be recorded in a configuration file. For example, if the sharing B is created later, after the sharing B is created, the operation also needs to be recorded in the configuration file, that is, the configuration file at this time may reflect that the MMC performs 2 times of sharing creation operations for the distributed storage system on the connected node, and creates the sharing a and the sharing B respectively.
Step S103: the configuration file is synchronized to each node in the distributed storage system.
In step S102, the operation information is stored in a configuration file, that is, a configuration file of a node to which the MMC is currently connected is stored, so that after the node switching is performed, other nodes can reproduce an operation that was previously performed on the failed node, and thus the scheme of the present application performs synchronization of the configuration file. That is, the configuration file is synchronized to each node other than the node to which the MMC is currently connected, so that the configuration file is stored in each node in the distributed storage system.
When the configuration file is synchronized to each node in the distributed storage system, the synchronization of the configuration file may be generally performed periodically, that is, the synchronization of the configuration file is triggered at intervals. For example, in an embodiment of the present invention, it may be selected that the synchronization of the configuration file is performed once each time the node to which the MMC is currently connected performs an update of the configuration file.
Step S104: and when the node connected currently fails, switching the nodes, and automatically executing corresponding operation aiming at the distributed storage system based on the configuration file stored in the node after switching.
When it is determined that the currently connected node has a fault, the node needs to be switched. As described above, the present application is directed to automatically resume operations executed before on a new node connected to an MMC after a failure occurs in the node connected to the MMC, so that after the failure occurs in the node connected to the MMC, node switching should be automatically performed to improve the execution efficiency of a scheme and reduce the workload of related workers.
In the foregoing step, in order to enable the automatic switching of the nodes in step S104, the nodes are connected using virtual IP. And setting a virtual IP for the distributed storage system, and connecting the distributed storage system through the virtual IP.
Because the distributed storage system is connected through the virtual IP, when the node connected at present is determined to be in fault, the node switching without perception of the client can be carried out through the drift of the virtual IP. That is, in an embodiment of the present invention, when it is determined that the currently connected node fails, the node switching performed in step S104 may specifically include: and when the node connected at present is determined to be in fault, switching the nodes without sensing of the client side through the drift of the virtual IP.
Due to the drift of the virtual IP, the node switching without sensing of the client can be carried out, so that the use experience of a user is improved.
In addition, it should be noted that, when performing the node switching without client perception through the drift of the virtual IP, the virtual IP may be kept unchanged, and only the corresponding relationship between the virtual IP and the corresponding node needs to be changed, for example, the MMC is originally connected to the node a of the distributed storage system through the virtual IP, and after the node a fails, the virtual IP drifts to the node B, and then the MMC may be connected to the node B of the distributed storage system through the virtual IP.
When the node connected currently is determined to be in fault, after the node is switched, due to the operation of synchronizing the previous configuration files, each node in the distributed storage system stores the configuration files, so that the corresponding operation aiming at the distributed storage system can be automatically executed based on the configuration files stored in the switched nodes. Namely, each operation originally executed in the fault node by the MMC is reproduced in the node after switching, and the process is automatically performed based on the configuration file in the node after switching, so that manual operation of workers is not needed, errors are not easy to occur, and the work efficiency is favorably ensured.
For example, in an embodiment of the present invention, determining that the node currently connected to the MMC has a fault may specifically include:
and when the connection timeout or connection failure occurs, determining that the currently connected node fails.
In this embodiment, if a connection timeout occurs or a connection failure occurs, it indicates that a network failure may occur or a node server itself fails, and therefore, both the cases may be considered as a node failure, that is, when a connection timeout occurs or a connection failure occurs, it may be determined that a node currently connected fails.
The detection of connection timeout or connection failure is simple and convenient, so the implementation mode is also a detection and judgment mode of node faults which is commonly used in practical application. Of course, in other embodiments, other types of node fault detection and determination manners may be used according to actual needs, and the implementation of the present invention is not affected. For example, in a specific situation, the node server itself has a certain fault detection function, and when the node server finds itself abnormal through self-detection, a prompt message can be output, so that the MMC regards the node as a faulty node, and can inform a worker to perform abnormal processing in time.
In an embodiment of the present invention, after determining that the currently connected node fails, the method may further include:
and when the connection with the node is restored again, determining that the node is restored to be normal and adding the node back to the distributed storage cluster.
In the embodiment, it is considered that when a node failure occurs in some occasions, the MMC determines that the currently connected node fails due to temporary reasons such as network fluctuation and the like instead of the failure of the node server, so that if the connection with the node is restored again, it can be determined that the node is restored to be normal in the embodiment, and the node can be added back to the distributed storage cluster, so as to effectively guarantee the performance of the distributed storage cluster.
Further, in an embodiment of the present invention, after determining that the currently connected node fails, the method may further include: and recording and storing the fault event. For example, the occurrence time of the fault event and the information such as the serial number of the fault server can be recorded, so that the subsequent maintenance work of the staff is facilitated, and the related records of the fault event are also beneficial to assisting the staff to perform the work such as analysis, troubleshooting and the like of the fault reason.
The management method of the distributed storage system provided by the embodiment of the invention can be applied to MMC and comprises the following steps: setting a virtual IP for the distributed storage system, and connecting the distributed storage system through the virtual IP; when the operation aiming at the distributed storage system is executed on the connected nodes, the operation information is saved in a configuration file; synchronizing the configuration file to each node in the distributed storage system; and when the node connected currently fails, switching the nodes, and automatically executing corresponding operation aiming at the distributed storage system based on the configuration file stored in the node after switching.
Specifically, in the scheme of the present application, through setting of the virtual IP and synchronization of the configuration file, after a node connected to the MMC fails, an operation executed before the node connected to the MMC can be conveniently and effectively recovered on a new node connected to the MMC.
In the scheme of the application, the virtual IP can be set for the distributed storage system, the distributed storage system is connected through the virtual IP, and due to the fact that the virtual IP is set, when the node connected at present is determined to be in fault, node switching can be automatically carried out, manual execution of workers is not needed, and therefore work efficiency is favorably improved. When the operation for the distributed storage system is executed on the connected node, the operation information is stored in the configuration file, that is, each operation executed before can be effectively reflected through the configuration file. And, the present application synchronizes the configuration file to each node in the distributed storage system. Therefore, when it is determined that the currently connected node fails, after the node is switched, based on the configuration file stored in the node after switching, the corresponding operation for the distributed storage system can be automatically executed. It can be seen that when the operation executed before is recovered on a new node connected by the MMC, the operation is automatically executed based on the configuration file in the node, so that the operation is convenient and efficient, and the working efficiency is effectively improved.
To sum up, the scheme of the application can effectively manage the distributed storage system, and after the node connected with the MMC breaks down, the operation executed before can be conveniently and effectively recovered on the new node connected with the MMC.
