All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
As described in the background art, in practical application, 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 the 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, after a period of time, if the physical disk is updated, the server does not receive updated information, so that the server cannot update the relevant information of the physical disk in time, and further, the information stored in the super fusion system for the physical disk included in the server is not matched with the information stored in the server itself.
Based on this, 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, the information of a first physical disk set included in the server by the super fusion system and the information of a second physical disk set used by the super fusion system and stored by the server are acquired, the two pieces of information are compared, so as to obtain the newly-added information or the deleted information of the physical disk used by the super fusion system in the server, and the stored information of the physical disk used by the super fusion system in the server is updated according to the newly-added information or the deleted information, that is, the newly-added information or the deleted information of the physical disk in the server is obtained by comparing the disk information in the super fusion system with the disk information in the server, so that the related information of the physical disk in the server can be updated after being used by the super fusion system, the information of the physical disk used by the super fusion system and the physical disk included in the super fusion system are kept consistent, and meanwhile, the error tolerance of the super fusion system of the information used by the super fusion system is easily displayed on the server is improved.
Referring to fig. 1, the flowchart of an information synchronization method of a super fusion system according to an embodiment of the present application is shown.
In the embodiment of the application, the super fusion system comprises one or more servers, and the information synchronization method of the super fusion system provided by the embodiment of the 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 stored by the server and used by the super fusion system.
In an embodiment of the present application, for any one server 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 is initialized 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 during the initialization phase 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 includes at least a unique identification (Small Computer System Interface ID, SCSIID) of the physical disks. The basic information also includes attribute information of the disk such as an identifier or an absolute path of the physical disk.
In the embodiment of the 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 that the super fusion system includes at the server.
After the super fusion system is initialized by the server, the new or deleted 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 disk set information and the second disk set information may be the same, reflecting that there is no change in the physical disks used by the super-fusion system by the server during the period of time.
However, in practical applications, after a period of time, the physical disk used by the super fusion system may change, for example, delete, add or replace, where 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 second disk set information of the second disk set used by the super fusion system is still stored in the server or is still stored in the server when the super fusion system is initialized, that is, when the physical disk used by the super fusion system in the server changes, 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 obtained by calling the virtualized bottom command. The first disk set information includes basic information of each of the one or more physical disks, and may be obtained in a list form.
In the embodiment of the application, the second disk set information of the second physical disk set stored by the server and used by the super fusion system is directly acquired locally at the server.
S102, comparing the first disk set information with the second disk set information, and determining the plug information of the physical disk used by the super fusion system in the server, wherein the plug information is the new information or the deletion information of the physical disk.
In the embodiment of the application, the plug 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 plug information of the physical disk is the new information or the deletion information of the physical disk. That is, since the super fusion system includes information of the physical disk in which the first disk set information is up-to-date and in real time, by comparing the first disk set information with the second disk set information, it is possible to determine whether a change of the physical disk used by the super fusion system on the server is a new physical disk or a deletion of the physical disk. Changing a physical disk is regarded as deleting the original physical disk and adding a physical disk.
The specific comparison of the first disk set information and the second disk set information can be achieved by the following way:
and judging whether the physical disks included in the first physical disk set belong to the second physical disk set at the same time, and if not, judging that the physical disks are newly 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, deleting the physical disks 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, a new or deleted physical disk on the server can be determined.
Because the first disk set information comprises basic information of the physical disks in the first physical disk set, and the second disk set information comprises basic information of the physical disks in the second physical disk set, 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 first physical disk set belong to the second disk set information at the same time, namely judging whether the unique identifiers of the physical disks in the first physical disk set occur at the same time at the second physical disk set information; the method specifically judges whether the physical disks included in the second physical disk set belong to the first physical disk set at the same time by judging whether the unique identifications of the physical disks in the second physical disk set belong to the first physical disk set at the same time, namely judging whether the unique identifications of the physical disks in the second physical disk set occur at the same time at the first physical disk set information.
And S103, updating the storage information of the physical disk used by the super fusion system in the server according to the plug 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 plug information of the physical disk obtained by comparing the first disk set information and 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 server comprises basic information and use information of the physical disk, wherein the use information is information about whether the physical disk is used by the super fusion system or not.
In the embodiment of the application, if the plug information is newly added information of the physical disk used by the super fusion system in the server, the corresponding relation between the newly added server and the newly added physical disk and the basic information of the newly added physical disk are added. That is, if the physical disk used by the super fusion system in the server is a new physical disk, the corresponding relationship between the server and the new physical disk and the basic information of the new physical disk need to be added in the database, so that the new physical disk is reflected in the server through the database to be used by the super fusion system. The specific adding corresponding relation can be that a record of the newly added physical disk is inserted into the database table, and the basic information of adding the newly added physical disk can be added into an association table of the database table, wherein the association table is a table of the newly added physical disk.
In the embodiment of the application, if the plug information is the deletion information of the physical disk used by the super fusion system in the server, the corresponding relation between the server and the deleted physical disk and the basic information of the deleted physical disk are deleted. That is, if the physical disk used by the super fusion system is a deleted physical disk when the server is initialized, the correspondence between the server and the deleted physical disk and the basic information of the deleted physical disk need to be deleted in the database to update the information of the physical disk used by the super fusion system stored in the database. Specifically, firstly, deleting an association table of a database table in the database, wherein the association table is a table of a deleted physical disk, and then deleting a corresponding relation between a server and the deleted physical disk in the database, wherein the deleted corresponding relation can be a record of the deleted physical disk in the database table.
In the embodiment of the application, after updating the storage information of the physical disk used by the super fusion system in the server, the server can scan the local physical adapter to obtain the basic information of the physical disk included on the current server, the number of the physical disk and the like, and synchronize the information into the database.
Referring to fig. 2, a schematic diagram of a super fusion system according to an embodiment of the present application is shown. In fig. 2, there are shown 2 servers included in the super fusion system, each of which is a node in the super fusion system, and each of which includes storage resources of the super fusion 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 server 1, the second physical disk set includes physical disk A and physical disk B, and for server 2, the second physical disk set includes physical disk C and 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 exchange, and for the server 1, the first set of physical disks includes the physical disk C and the physical disk B, and for the server 2, the first set of physical disks includes the physical disk a and the physical disk D.
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, acquiring first disk set information and second disk set information of the server 1, wherein 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, and determining that the physical disk C is 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 a physical disk deleted by the super fusion system in the server 1. Since the record of the newly added physical disk C is already stored in the database in the server 2 before the physical disk C, the newly added record of the physical disk C is not required to be added again, and only the corresponding relationship between the physical disk C and the server 2 is required to be modified to be the corresponding relationship between the physical disk C and the server 1, specifically, the table association relationship of the physical disk C is modified, and the physical disk C is associated with the server 1.
For the server 2, acquiring first disk set information and second disk set information of the server 2, wherein 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, and determining that the physical disk A is 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 C is a physical disk deleted by the super fusion system in the server 1. Since the corresponding relation between the physical disk C and the server 1 is modified to be the corresponding relation between the physical disk C and the server 2 before, the physical disk C is not in the server 2, so that 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 before the physical disk a is in the server 1, the newly added record of the physical disk a is not needed to be added again, and only the corresponding relation between the physical disk a and the server 1 is required to be modified to be the corresponding relation between the physical disk a and the server 2, specifically, the table association relation between the physical disk a is modified, and the physical disk a is associated with the server 2.
