Embodiment Construction
[0043] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0044] At present, when restoring a CFS storage domain, it is necessary to re-set the heartbeat disk for the CFS storage domain and manually re-add the corresponding configuration information, which reduces the recovery efficiency and makes it difficult to guarantee the restored CFS storage domain and the original CFS storage Domains are identical, reducing the accuracy of recovered data. Therefore, the present application provides a CFS storage domain recovery solution, which can i...

The invention discloses a CFS storage domain recovery method, which comprises the following steps: if a virtualization system is deployed in a host in a to-be-recovered CFS storage domain, distinguishing a heartbeat disk and a data disk in storage equipment according to disk identification information in the storage equipment; adding the heartbeat disk and the data disk to a CFS storage domain; and configuring the CFS storage domain according to the configuration information in the heartbeat disk so as to recover the CFS storage domain. According to the method and the device, the recovery efficiency of the CFS storage domain can be improved, and the consistency of the CFS storage domain before and after recovery can be guaranteed, so that the high reliability and the high availability of the CFS storage domain are guaranteed. Correspondingly, the CFS storage domain recovery device and equipment and the readable storage medium disclosed by the invention also have the above technical effects.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to a method, device, equipment and readable storage medium for recovering a CFS storage domain. Background technique [0002] CFS (Cluster File System, cluster file system) is also called a CFS storage domain. When a host in a CFS storage domain is seriously damaged, it is necessary to restore the CFS storage domain in time. When restoring the CFS storage domain, it is necessary to repair or replace the host, and redeploy the virtualization system on the repaired or replaced host, and then add the disks in the original storage device to the CFS storage domain; reset the heartbeat disk, and Configure the corresponding configuration information in the heartbeat disk. [0003] Among them, when setting the heartbeat disk and configuring the corresponding configuration information in the heartbeat disk, it is necessary to format a disk added to the CFS storage domain and ma...
