Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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.
At present, when a CFS storage domain is recovered, a heartbeat disc needs to be set for the CFS storage domain again, corresponding configuration information needs to be added manually again, so that the recovery efficiency is reduced, and it is difficult to ensure that the recovered CFS storage domain is completely the same as the original CFS storage domain, so that the accuracy of data recovery is reduced. Therefore, the CFS storage domain recovery scheme is provided, the recovery efficiency of the CFS storage domain can be improved, and the consistency of the CFS storage domain before and after recovery is guaranteed.
Referring to fig. 1, an embodiment of the present application discloses a first CFS storage domain recovery method, including:
and S101, if a virtualization system is deployed in a host in the CFS storage domain to be recovered, distinguishing a heartbeat disk and a data disk in the storage device according to disk identification information in the storage device.
In this embodiment, distinguishing the heartbeat disc and the data disc in the storage device according to the disc identification information in the storage device includes: scanning the storage device to read the disk identification information; the disk identification information includes at least: first identification information and second identification information; if the first identification information is read, determining the magnetic disk corresponding to the first identification information as a heartbeat disk; and if the second identification information is read, determining the magnetic disk corresponding to the second identification information as a data disk. The discriminated heartbeat disc and data disc may be recorded in a list form.
That is to say, after the CFS storage domain is initially created, first identification information is constructed for the heartbeat disk in the CFS storage domain, and second identification information is constructed for the data disk in the CFS storage domain; and storing the first identification information and the second identification information as disk identification information to a storage device. Therefore, the storage device can store the disk identification information belonging to the CFS storage domain, and when the CFS storage domain needs to be recovered, the heartbeat disk and the data disk belonging to the CFS storage domain are distinguished according to the disk identification information stored in advance, so that formatting operation is avoided.
The heartbeat disc is used for storing relevant configuration information and parameters of the CFS storage domain. Data disks are used to store data.
S102, adding a heartbeat disk and a data disk to a CFS storage domain;
and S103, configuring the CFS storage domain according to the configuration information in the heartbeat disc so as to recover the CFS storage domain.
The structural composition of the CFS storage domain is shown in fig. 3, and in fig. 3, 3 hosts are included: HostA, HostB, HostC; the heartbeat disc can ensure the survival state of each host in the storage domain, and the data disc can be used for creating shared storage for the virtual machine in the virtualization system to use; on each host. The normal operation of the CFS storage domain is maintained by configuration files and parameters and corresponding services.
When a CFS storage domain is created for the first time, a heartbeat disc needs to be formatted, corresponding identification information (namely first identification information) is written on the heartbeat disc, and meanwhile configuration information of an original storage domain is recorded; when the data disc added to the CFS storage field is formatted, the data disc is also written with some identification information (i.e., the second identification information).
When the CFS storage domain is severely damaged, the virtualization system may completely lose the related records of the previous CFS storage domain due to the reinstallation of the virtualization system, and then the recovery may be performed according to the method provided in this embodiment. That is, the heartbeat disc and the data disc are distinguished according to the first identification information written on the heartbeat disc and the second identification information written on the data disc, and the CFS storage domain is recovered accordingly, and the corresponding disc is added to the latest CFS storage domain without formatting the disc in the recovery process. If new configuration information needs to be added in the CFS storage domain, the new configuration information is added on the basis of the configuration information in the heartbeat disc.
It can be seen that, in the present embodiment, when a CFS storage domain is restored, an original heartbeat disc and a data disc of the CFS storage domain to be restored can be directly distinguished, so that the original heartbeat disc and the data disc of the CFS storage domain to be restored can be directly added to the CFS storage domain, and the CFS storage domain is configured by using configuration information in the original heartbeat disc, thereby completing the restoration of the CFS storage domain. The scheme can improve the recovery efficiency of the CFS storage domain, and can ensure the consistency of the CFS storage domain before and after recovery, thereby ensuring the high reliability and high availability of the CFS storage domain.
Referring to fig. 2, an embodiment of the present application discloses a second CFS storage domain recovery method, including:
s201, if a virtualization system is deployed in a host in a CFS storage domain to be recovered, distinguishing a heartbeat disk and a data disk in a storage device according to disk identification information in the storage device;
s202, judging whether the heartbeat disc and the data disc both belong to a CFS storage domain; if yes, go to S203; if not, executing S205;
s203, adding the heartbeat disc and the data disc to a CFS storage domain, and executing S204;
s204, configuring a CFS storage domain according to the configuration information in the heartbeat disc so as to recover the CFS storage domain;
s205, determining a disk belonging to a CFS storage domain from the heartbeat disk and the data disk, adding the disk belonging to the CFS storage domain, and determining a heartbeat disk from the disks belonging to the CFS storage domain; and S204 is performed.
In this embodiment, after recovering the CFS storage domain, the method further includes: and if the CFS storage domain needs to be newly added with a heartbeat disc or a data disc, adding the disc without the disc identification information in the storage device into the CFS storage domain to serve as the newly added heartbeat disc or data disc.
In this embodiment, configuring the CFS storage domain according to the configuration information in the heartbeat disc includes: and reading the configuration information in the heartbeat disk, updating the configuration information into a configuration file in a CFS storage domain, and loading the configuration file. The configuration files of the CFS storage domain correspond to the hosts in the CFS storage domain in a one-to-one mode, and the hosts can be servers.
The method provided according to the present embodiment may implement the following recovery procedure.
Assume that there are three hosts (A, B, C), three heartbeats (H1, H2, H3), five blocks (D1, D2, D3, D4, D5) in the CFS storage domain, where four of the five blocks (D1, D2, D3, D5) create a shared storage pool. In this CFS storage domain, 8 disks on the storage device are mapped on each host.
If the CFS storage domain is severely damaged, the recovery process is as follows: firstly, repairing the hosts (A, B and C), reinstalling the virtualization system on the hosts, and remapping 8 disks in the storage device to the three hosts, namely adding the 8 disks to the CFS storage domain; further, the 8 disks are scanned to distinguish three heartbeats (H1, H2, H3) and four blocks (D1, D2, D3, D5), where the reason why D4 is not scanned is: the data disks used to create the shared storage pool, in which the associated identification information is recorded, are added to the CFS storage domain but are not used to create the shared storage pool, and there is no associated identification information, so D4 cannot be scanned. Where the data disks added to the CFS storage domain that were not used to create the shared storage pool also have no substantive data, D4 may be re-added to the CFS storage domain after the CFS storage domain is restored to serve as a heartbeat disk or a data disk.
Furthermore, three heartbeats (H1, H2, H3) and four blocks (D1, D2, D3, D5) are used for recovering the CFS storage domain by the host, and the three heartbeats do not need to be formatted and can be directly used in the recovery process. After the CFS storage domain recovery is complete, shared storage pool creation work may be performed for the four block data disks (D1, D2, D3, D5).
It should be noted that other implementation steps in this embodiment are the same as or similar to those in the above embodiment, and therefore, the description of this embodiment is omitted here.
As can be seen from the above, in the embodiment, when the CFS storage domain is restored, the original heartbeat disc and the original data disc of the CFS storage domain to be restored can be directly distinguished, so that the original heartbeat disc and the original data disc of the CFS storage domain to be restored can be directly added to the CFS storage domain, and the CFS storage domain is configured by using the configuration information in the original heartbeat disc, thereby completing the restoration of the CFS storage domain. The scheme can improve the recovery efficiency of the CFS storage domain, and can ensure the consistency of the CFS storage domain before and after recovery, thereby ensuring the high reliability and high availability of the CFS storage domain. And can also provide a reliable basis for recovery of post-disaster stored data or recovery of other data.
