Upgrade Shared Volumes on SharedBlock Primary Storage

To upgrade shared volumes on SharedBlock primary storage, follow these steps:
  1. Run the following command to check whether there are any volumes need to be converted into the correct format among the detached shared volumes to be upgraded:
    [root@localhost ~]# zstack-ctl fix_sharedvolume --operation convert_volume --admin-password password
  2. Run the following command to convert the volume format of the shared volumes fixed by step 1 from qcow2 to raw:
    [root@localhost ~]# zstack-ctl fix_sharedvolume --operation convert_volume --admin-password password --dryrun False
  3. Run the following command to check deletable shared volumes that were originally in qcow2 format:
    [root@localhost ~]# zstack-ctl fix_sharedvolume --operation delete_qcow2_volume --admin-password password
  4. Ensure the data integrity after format conversion. Then run the following command to delete those shared volumes which were originally in qcow2 format:
    [root@localhost ~]# zstack-ctl fix_sharedvolume --operation delete_qcow2_volume --admin-password password --dryrun False
  5. Run the following command to create the image file based on the shared volume snapshots to make a backup:
    [root@localhost ~]# zstack-ctl fix_sharedvolume --operation commit_snapshot_to_image --admin-password password --backup-storage-uuid  XXXXX  --dryrun False
  6. Run the following command to delete the shared volume snapshots that were originally in qcow2 format:
    [root@localhost ~]# zstack-ctl fix_sharedvolume --operation delete_shared_volume_snapshots --admin-password password --dryrun False
