So, have PVE 2.1 (2.1-1/f9b0f63a), 6 nodes.
Attached iSCSI storage with several LUNs.
So, after night backup NAS01LUN0VG0 is dissapeared and get follow:
At iSCSI storage server all fine - no errors.
I can fix it:
vgcfgrestore NAS01LUN0VG0
and then
vgchange -ay NAS01LUN0VG0
after that NAS01LUN0VG0 is come back.
But, why it happening?
