Hi Has anyone experiencing the following issue with Storage Domain -

Failed to activate Storage Domain cLUN-R940-DC2-dstore01 -- VDSM command ActivateStorageDomainVDS failed: Storage domain does not exist: (u'1b0ef853-fd71-45ea-8165-cc6047a267bc',)

Currently, the storge Domain is Inactive and strangely, the VMs are running as normal. We can't manage or extend the volume size of this storage domain. The pvscan shows as: [root@uk1-ion-ovm-18 pvscan /dev/mapper/36000d310056978000000000000000014: Checksum error at offset 4397954425856 Couldn't read volume group metadata from /dev/mapper/36000d310056978000000000000000014.

I have tired the following steps: 1. Restarted ovirt-engine.service 2. tried to restore the metadata using vgcfgrestore but it failed with the following error:

[root@uk1-ion-ovm-19 backup]# vgcfgrestore 36000d310056978000000000000000014 Volume group 36000d310056978000000000000000014 has active volume: .

Do you really want to proceed with restore of volume group "36000d310056978000000000000000014", while 1 volume(s) are active?

Please let me know if anyone knows any possible resolution.
