Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Referring to fig. 1, fig. 1 is a first flowchart of a NAS-based storage system management method according to an embodiment of the present application.
The storage system management method based on NAS, provided by the embodiment of the application, is applied to a target service site in a storage system, and can comprise the following steps:
step S101: and determining a target service node for processing the target service from service nodes of the target service site, wherein each service node in the target service site shares a target storage unit.
The actual application is heavy, and the target service site can firstly determine the target service node for processing the target service in the service nodes of the target service site.
In a specific application scenario, in the process of determining a target service node for processing a target service, a service node with the fastest processing rate may be used as the target service node, or a service node with the smallest load may be used as the target service node.
It should be noted that, the type of the storage system may be determined according to an application scenario, for example, the storage system may be a NAS storage system, etc., and the number of service sites in the storage system, the number of service nodes in a single service site, the service type, etc. may be determined according to actual needs.
It should be further noted that the target service site refers to a service site in the storage system, where service management and control are required, and the service site may be any service site in the storage system, where functions of all service sites in the storage system are the same as those of the target service site. Furthermore, the target storage unit refers to a storage unit in the target service site, and the service nodes in the target service site share the target storage unit, that is, the service nodes in the service site share one storage unit.
Step S102: judging whether the target service node fails; if the target service node fails, step S103 is performed.
Step S103: and forwarding the target service to other service nodes which do not fail in the target service site for processing.
In practical application, after determining a target service node for processing the target service, the target service station can determine whether the target service node fails, and if so, the target service can be transferred to other service nodes which are not failed in the target service station for processing, so as to ensure the processing continuity of the service in the service station; accordingly, if it is determined that the target service node has not failed, the target service node may continue to process the target service, and so on.
Step S104: and transmitting the target service data recorded by the target storage unit of the target service site to other storage units of other service sites through the interconnection links among the storage units of the service sites.
Step S105: and responding to the failure of the target service site, ending the processing of the target service so that other service sites can continue to process the target service based on the target service data in other storage units.
In practical application, the target service data of the target service processed by the target service node or other service nodes is stored in the target storage unit, the target service node needs to transmit the target service data recorded by the target storage unit of the target service station to other storage units of other service stations through the interconnection link between the storage units of the service station, so that after the target service node fails and finishes processing the target service, the other service stations can continue processing the target service based on the target service data in the other storage units, so as to ensure the processing continuity of the service between the service stations. And because the target service data are stored in other storage units, the target service can be processed only by enabling other service sites without restarting the target service, and the continuous processing of the target service can be further ensured.
It should be noted that, a plurality of service nodes may be disposed in other service sites, and the functions of other service sites may refer to the functions of the target service site. In addition, information of other service sites, such as ip, key, certificate, password, etc., can be input into the service sites, so that verification, generation, etc. of interconnection links between the service sites can be performed.
The storage system management method based on the NAS is applied to a target service site in a storage system, and a target service node for processing target service is determined from service nodes of the target service site; judging whether the target service node fails; if the target service node fails, the target service is forwarded to other service nodes which do not fail in the target service site for processing; transmitting the target service data recorded by the target storage unit of the target service site to other storage units of other service sites through the interconnection links among the storage units of the service sites; responding to the failure of the target service site, ending the processing of the target service so that other service sites continue to process the target service based on the target service data in other storage units; wherein each service node in the target service site shares the target storage unit. In the method, a plurality of service nodes exist in the target service site, and all the service nodes share the target storage unit, so that when the target service is transferred to other service nodes for processing by the target service node, the other service nodes can continue to process the target service according to the target service data recorded in the target storage unit, and seamless drifting of the service among the service nodes is realized; and the target service stations transmit the target service data to other storage units of other service stations through the interconnection links among the storage units, so that after the target service is processed by the target service stations through the other service stations, the other service stations can continue to process the target service according to the target service data in the other storage units, seamless drifting of the service among the service stations is realized, and service processing continuity of the storage system is improved.
Referring to fig. 2, fig. 2 is a second flowchart of a NAS-based storage system management method according to an embodiment of the present application.
The storage system management method based on NAS, provided by the embodiment of the application, is applied to a target service site in a storage system, and can comprise the following steps:
step S201: and determining a target service node for processing the target service from service nodes of the target service site, wherein each service node in the target service site shares a target storage unit.
Step S202: judging whether the target service node fails; if the target service node fails, step S203 is performed.
Step S203: and forwarding the target service to other service nodes which do not fail in the target service site for processing.
Step S204: determining information of a target volume space allocated for a target service in a target storage unit; determining target service data stored in each target volume space; and establishing a target storage corresponding relation between the target volume space and target service data.
In practical application, before the target service site transmits the target service data recorded by the target storage unit of the target service site to other storage units of other service sites, the target service can be accurately and continuously processed for other service sites, and the information of the target volume space allocated for the target service can be determined in the target storage unit; determining target service data stored in each target volume space; and establishing a target storage corresponding relation between the target volume space and the target service data so that other service stations can virtually form other volume spaces consistent with the target volume space in other storage units according to the information of the target volume space, and then storing the target service data into the corresponding other volume spaces based on the target storage corresponding relation, thereby enabling the storage of the target service data in the other service stations to be consistent with the storage of the target service data in the target service stations, and facilitating the subsequent connection-free processing of the target service by the other service stations.
Step S205: determining information of a target service; and establishing a target binding relation between the target service and the target volume space.
Step S206: taking the information of the target volume space, the target storage corresponding relation, the information of the target service and the target binding relation as target service processing information; and transmitting the target service processing information to other service sites through the interconnection link.
In practical application, the information of the target service can be determined; establishing a target binding relation between a target service and a target volume space; taking the information of the target volume space, the target storage corresponding relation, the information of the target service and the target binding relation as target service processing information; and transmitting the target service processing information to other service sites through the interconnection link. After receiving the information of the target service, the other service stations can determine other volume spaces consistent with the target volume space in other storage units according to the target binding relation, so that the target service can be processed according to the other volume spaces.
Step S207: and transmitting the target service data recorded by the target storage unit of the target service site to other storage units of other service sites through the interconnection links among the storage units of the service sites.
Step S208: receiving other service processing information and other service data transmitted by other service sites through an interconnection link; and according to the information of other volume spaces in the other business processing information, virtualizing the other volume spaces in the target storage unit.
Step S209: according to other storage corresponding relations in other service processing information, storing other service data into corresponding other volume spaces; and processing other services based on other volume spaces according to other binding relations in other service processing information.
In practical application, when other service stations process other services preferentially, the processing process may refer to the process of processing the target service by the target service station, at this time, the target service station receives corresponding service information of the other service stations, that is, before responding to the failure of the target service station and ending the processing of the target service, the target service station may also receive other service processing information and other service data transmitted by the other service stations through the interconnection link, where the other service processing data is the service data of other services recorded in other storage units; according to the information of other volume spaces in other service processing information, other volume spaces are virtually formed in the target storage unit, and the other volume spaces are volume spaces in which other service data are stored in other storage spaces; according to other storage corresponding relations in other service processing information, other service data are stored in corresponding other volume spaces, and other storage corresponding relations are namely storage corresponding relations between other volume spaces and the stored other service data; and processing other services based on other volume spaces according to other binding relations in the other service processing information, wherein other jumping relations are binding relations between other services and other volume spaces.
Step S210: and responding to the failure of the target service site, ending the processing of the target service so that other service sites can continue to process the target service based on the target service data in other storage units.
In practical application, the target service site can judge whether service nodes in the target service site all fail according to a preset time period in the process of responding to the failure of the target service site and ending the processing of the target service; if the service nodes in the target service site all fail, the heartbeat packet is forbidden to be sent to an arbitration system in the storage system, so that the arbitration system judges the failure of the target service site based on the heartbeat packet, for example, the arbitration system can judge the failure of the target service site after the heartbeat packet of the target service site is not received in two continuous rounds; if the target service site has a normal service node, sending a heartbeat packet to an arbitration system; wherein the arbitration system is coupled to each service site in the storage system. For the sake of understanding, it is assumed that each service station sends a heartbeat packet to the arbitration system every 1/3 of the cluster period time and transmits its current status information to the arbitration system, if no heartbeat information is sent in more than two cluster periods, the arbitration system considers that the service station is offline, and when the second service station sends the heartbeat packet, the arbitration system may transmit the service information that the second service station needs to take over to the second service station, so that the second service station continues to perform service processing, and so on.
In a specific application scenario, a main service node may be designated in a target service site to perform functions such as performing service processing preferentially or performing communication with an arbitration system, and accordingly, whether other service nodes are normal or not may be determined by checking whether other service nodes may communicate with the main service node, for example, if a certain service node cannot communicate with the main service node, then the service node may be considered to be faulty, and so on.
In practical application, in order to facilitate distinguishing different sites in the storage system, the target service site can also determine cluster names of clusters formed by service nodes in the target service site; determining a hash value of the cluster name; determining the number of the target volume space; and generating a universal unique identification code corresponding to the target volume space according to the manufacturer number, the hash value and the serial number of the target service site. The number of the target volume space may be a processing number of the configuration, for example, number 0 may indicate that the target volume space is a volume space on a default configuration disk.
In practical application, after responding to the failure of the target service site and finishing processing the target service, responding to the target service site to restore to normal, and firstly performing cache synchronization with other service sites through an interconnection link; and after the synchronization of the buffer is completed, carrying out service processing to ensure the consistency of the data.
In a specific application scenario, after the buffer synchronization is completed and the service processing is performed, the target service site can also judge whether the target service site is a main site for processing the target service; and if the target service site is a main site for processing the target service, acquiring data to be written of the target service, and writing the data to be written into the target storage unit. Namely, only the current main site of the target service can write data, thereby avoiding the writing disorder of the target service and ensuring the processing stability of the target service.
