Hi,
For the first time in many months I have run into some trouble with oVirt (4.3.4.3) and I
need some help.
Yesterday, I noticed one of my iSCSI storage domains was almost full, and tried to move a
disk image off of it, to another domain. This failed, and somewhere in the process, the
whole storage domain went to status 'Inactive'.
From engine.log:

was deactivated by system because it's not visible by any of the hosts.
The thing is, the domain is still functional on all my hosts. It carries over 50 disks,
and all involved VMs are up and running, and don't seem to have any problems. Also,
'iscsiadm' on all hosts seems to indiciate that everything is fine with this
specific target and reading from the device with dd, or getting its size with
'blockdev' all works without issue.
When I try to reactivate the domain, these errors are logged:

On the SPM host, there are errors that indicate problems with the LVM volume group:

any additional information, please let me know!
It appears the VG metadata is corrupt:

Is this fixable? If so, how?
