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.

Failed to read metadata summary from /dev/mapper/36000d310056978000000000000000014
Failed to scan VG 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: .
WARNING: Found 1 active volume(s) in volume group "36000d310056978000000000000000014".
Restoring VG with active LVs, may cause mismatch with its metadata.
Do you really want to proceed with restore of volume group "36000d310056978000000000000000014", while 1 volume(s) are active? [y/n]: y

Please let me know if anyone knows any possible resolution.
