All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As described in the background art, in practical applications, scenes such as replacement, addition, deletion and the like of a physical disk in a server often occur, when the physical disk in the server is used by a super-fusion system, the replacement, addition, deletion and the like of the physical disk only feed back to the super-fusion system, for the server itself, after the physical disk in the server is used by the super-fusion system, the physical disk used by the super-fusion system does not feed back relevant information to the server itself, and after a period of time, if the information of the physical disk is updated, the server does not receive the updated information, so that the server cannot update the relevant information of the physical disk in time, and further the information of the physical disk included in the server and the information of the physical disk stored by the server in the super-fusion system are not matched.
Based on this, an embodiment of the present application provides an information synchronization method for a super-fusion system, which includes, for any one server in the super-fusion system, obtaining information of a first physical disk set included in the server of the super-fusion system and information of a second physical disk set used by the super-fusion system and stored by the server, comparing the two pieces of information to obtain new information or deleted information of a physical disk used by the super-fusion system in the server, and updating storage information of the physical disk used by the super-fusion system in the server according to the new information or deleted information, that is, comparing information of a disk in the super-fusion system with information of a disk in the server to obtain new information or deleted information of the physical disk in the server, so that the physical disk in the server can still update relevant information of the physical disk after being used by the super-fusion system, the consistency of the information of the physical disk used by the super fusion system in the server and the information of the physical disk included in the super fusion system is kept, and meanwhile, the information of the physical disk used by the super fusion system is correctly displayed on the server, so that the usability and the fault tolerance of the super fusion system can be improved, and the performance of the super fusion system is improved.
Referring to fig. 1, the figure is a flowchart of an information synchronization method of a super-fusion system according to an embodiment of the present application.
In the embodiment of the present application, the super-fusion system includes one or more servers, and the information synchronization method of the super-fusion system provided in the embodiment of the present application is applied to the servers.
The information synchronization method of the super-fusion system provided by the embodiment comprises the following steps:
s101, acquiring first disk set information of a first physical disk set included in the super fusion system and second disk set information of a second physical disk set used by the super fusion system and stored by the server.
In an embodiment of the present application, for any one of the servers in the super-fusion system, the server includes one or more physical disks used by the super-fusion system, and when the super-fusion system initializes at the server, the server stores information of the one or more physical disks used by the super-fusion system, that is, the second disk set information. The second physical disk set is one or more physical disks stored by the server and used by the super-fusion system in the initialization stage of the super-fusion system.
The second disk set information includes the number of physical disks in the second disk set and basic information of the physical disks, and the basic information at least includes unique identifiers (SCSIIDs) of the physical disks. The basic information also includes attribute information of the disk, such as a drive letter or an absolute path of the physical disk.
In an embodiment of the present application, the first disk set information is first disk set information of a first physical disk set included in the super-fusion system, that is, the super-fusion system also stores information of one or more physical disks used in the server. The first set of physical disks is one or more physical disks included in the server by the super-fusion system.
After the super-fusion system is initialized in the server, addition or deletion of the physical disk is not fed back to the server any more, and only the super-fusion system is fed back.
After a period of time has elapsed, the first set of disk information and the second set of disk information may be the same, which reflects that the server is not changing any physical disks used by the hyper-converged system during the period of time.
However, in practical applications, after a period of time elapses, the physical disk of the server used by the super-fusion system may be changed, such as deleted, added, or replaced, the first disk set information of the physical disk in the first disk set included in the super-fusion system is the latest and real-time information, and since the server cannot receive the feedback information of the physical disk, the server still stores the second disk set information of the second disk set used by the super-fusion system when the super-fusion system is initialized, that is, when the physical disk used by the super-fusion system in the server is changed, the first disk set information and the second disk set information are different.
In the embodiment of the application, the first disk set information of the first physical disk set included in the current super-fusion system can be acquired by calling a virtualization bottom layer command. The first disk set information includes basic information of each physical disk of the one or more physical disks, and may be obtained in the form of a list.
In the embodiment of the application, the second disk set information of the second physical disk set used by the super-fusion system and stored by the server is directly obtained locally at the server.
S102, comparing the first disk set information with the second disk set information, and determining plug-pull information of a physical disk used by the super fusion system in the server, wherein the plug-pull information is added information or deleted information of the physical disk.
In the embodiment of the application, the plugging and unplugging information of the physical disk used by the super-fusion system in the server can be determined by comparing the first disk set information with the second disk set information, wherein the plugging and unplugging information of the physical disk is newly added information or deleted information of the physical disk. That is, since the super-fusion system includes the information of the physical disk of which the first disk set information is the latest and real-time information, the change of the physical disk used by the super-fusion system on the server can be determined by comparing the first disk set information with the second disk set information, and the physical disk is added or deleted. The replacement of the physical disk is regarded as deleting the original physical disk and adding a new physical disk.
Specifically, the first disk set information and the second disk set information may be compared in the following manner:
whether the physical disks included in the first physical disk set belong to the second physical disk set at the same time can be judged, and if not, the physical disks are the physical disks newly added and used by the super-fusion system in the server.
And then, continuously judging whether the physical disks included in the second physical disk set belong to the first physical disk set at the same time, if not, the physical disks are the physical disks deleted and used by the super-fusion system in the server.
By comparing the first disk set information with the second disk set information in the above manner, the physical disk added or deleted on the server can be determined.
Because the first disk set information includes basic information of physical disks in the first physical disk set, and the second disk set information includes basic information of physical disks in the second physical disk set, it can be specifically determined whether physical disks included in the second physical disk set belong to the first physical disk set at the same time by determining whether unique identifiers of physical disks in the first physical disk set belong to the second disk set information at the same time, that is, determining whether unique identifiers of physical disks in the first physical disk set appear in the second physical disk set information at the same time; whether the physical disks included in the second physical disk set belong to the first physical disk set at the same time can be specifically judged by judging whether the unique identifiers of the physical disks in the second physical disk set belong to the first disk set information at the same time, that is, judging whether the unique identifiers of the physical disks in the second physical disk set appear in the first physical disk set information at the same time.
S103, updating the storage information of the physical disk used by the super fusion system in the server according to the plugging information.
In the embodiment of the application, the storage information of the physical disk used by the super-fusion system in the server is updated according to the plugging and unplugging information of the physical disk obtained by comparing the first disk set information with the second disk set information.
The storage information of the physical disk used by the super-fusion system in the server is stored in a database, the storage information comprises the corresponding relation between the server and the physical disk, and the basic information and the use information of the physical disk, wherein the use information is the information of whether the physical disk is used by the super-fusion system.
In the embodiment of the application, if the plugging information is newly added information of a physical disk used by the super fusion system in the server, the corresponding relationship between the newly added server and the newly added physical disk and the basic information of the newly added physical disk are obtained. That is, if the physical disk used by the super-fusion system in the server is the newly added physical disk, the corresponding relationship between the server and the newly added physical disk and the basic information of the newly added physical disk need to be added to the database, so as to reflect that the newly added physical disk in the server is used by the super-fusion system through the database. The specific addition of the corresponding relationship may be inserting a record of a newly added physical disk into the database table, and adding the basic information of the newly added physical disk may be performed in an association table of the database table, where the association table is a table of the newly added physical disk.
In the embodiment of the application, if the plugging information is deletion information of a physical disk used by the super fusion system in the server, the corresponding relation between the server and the physical disk used for deletion and the basic information of the physical disk used for deletion are deleted. That is, if the physical disk used by the super-fusion system during initialization of the server is a deleted physical disk, the corresponding relationship between the server and the deleted physical disk and the basic information of the deleted physical disk need to be deleted in the database, so as to update the information of the physical disk used by the super-fusion system in the server stored in the database. Specifically, an association table of a database table is deleted in the database, where the association table is a table of a deleted physical disk, and then a correspondence between the server and the deleted physical disk is deleted in the database, where the deletion correspondence may be a record of the deleted physical disk in the database table.
In the embodiment of the application, after the storage information of the physical disk used by the super-fusion system in the server is updated, the server may scan the local physical adapter to obtain the basic information of the physical disk, the number of the physical disks, and the like included in the current server, and synchronize the information into the database.
Fig. 2 is a schematic diagram of a super-fusion system according to an embodiment of the present disclosure. In fig. 2, 2 servers included in the super-converged system are shown, each server is a node in the super-converged system and includes storage resources of the super-converged system. When the super-fusion system is initialized on the server, the physical disk in the server is used as the super-fusion system, and the use state of the used physical disk is marked as used.
The server 1 shown in fig. 2 includes a physical disk a and a physical disk B at the time of initialization, and the server 2 includes a physical disk C and a physical disk D at the time of initialization. That is, for the server 1, the second set of physical disks includes a physical disk a and a physical disk B, and for the server 2, the second set of physical disks includes a physical disk C and a physical disk D.
After a period of time, the physical disk a in the server 1 and the physical disk C in the server 2 are exchanged, and then the first set of physical disks includes the physical disk C and the physical disk B for the server 1, and includes the physical disk a and the physical disk D for the server 2.
In the server 1 and the server 2, the first disk set information of the first physical disk set and the second disk set information of the second physical disk set are different.
For the server 1, first disk set information and second disk set information of the server 1 are obtained, the first disk set information is information of a physical disk C and a physical disk B, the second disk set information is information of a physical disk a and a physical disk B, the physical disk C is determined to be a physical disk newly added by the super fusion system in the server 1 by comparing the first disk set information with the second disk set information, and the physical disk a is determined to be a physical disk deleted by the super fusion system in the server 1. Since the newly added record of the physical disk C is already stored in the database in the server 2 before, the newly added record of the physical disk C does not need to be added again, and only the correspondence between the physical disk C and the server 2 needs to be modified to be the correspondence between the physical disk C and the server 1, specifically, the table association relationship of the physical disk C is modified to associate the physical disk C with the server 1.
For the server 2, first disk set information and second disk set information of the server 2 are obtained, the first disk set information is information of a physical disk a and a physical disk D, the second disk set information is information of a physical disk C and a physical disk D, the physical disk a is determined to be a physical disk added by the super fusion system in the server 1 by comparing the first disk set information with the second disk set information, and the physical disk C is determined to be a physical disk deleted by the super fusion system in the server 1. Since the correspondence between the physical disk C and the server 1 is modified to the correspondence between the physical disk C and the server 2 before, and the physical disk C is not already in the server 2, only the physical disk a is newly added, and since the record of the newly added physical disk a is already stored in the database in the server 1 before, the newly added record of the physical disk a does not need to be added again, only the correspondence between the physical disk a and the server 1 needs to be modified to be the correspondence between the physical disk a and the server 2, specifically, the table association relationship of the physical disk a is modified, and the physical disk a is associated with the server 2.
The embodiment of the application provides an information synchronization method of a super-fusion system, aiming at any one server in the super-fusion system, acquiring information of a first physical disk set included in the server by the super-fusion system and information of a second physical disk set used by the super-fusion system and stored by the server, comparing the two information to obtain added information or deleted information of a physical disk used by the super-fusion system in the server, updating storage information of the physical disk used by the super-fusion system in the server according to the added information or the deleted information, namely comparing information of a disk in the super-fusion system with information of a disk in the server to obtain added information or deleted information of the physical disk in the server, so that the physical disk in the server can still update related information of the physical disk after being used by the super-fusion system, the consistency of the information of the physical disk used by the super fusion system in the server and the information of the physical disk included in the super fusion system is kept, and meanwhile, the information of the physical disk used by the super fusion system is correctly displayed on the server, so that the usability and the fault tolerance of the super fusion system can be improved, and the performance of the super fusion system is improved.
