Hi,
Something weird is going on with our ovirt node 4.3.8 install mounting a
nfs share.
We have a NFS domain for a couple of backup disks and we have a couple
of 4.2 nodes connected to it.
Now I'm adding a fresh cluster of 4.3.8 nodes and the backupnfs mount
doesn't work.
(annoying you cannot copy the text from the events view)
The domain is up and working
ID:f5d2f7c6-093f-46d6-a844-224d92db5ef9
Size:10238 GiB
Available:2491 GiB
Used:7747 GiB
Allocated:3302 GiB
Over Allocation Ratio:37%
Images:7
Path:*.*.*.*:/data/ovirt
NFS Version:AUTO
Warning Low Space Indicator:10% (1023 GiB)
Critical Space Action Blocker:5 GiB
But somehow the node appears to thin thinks it's an LVM volume? It tries
to find the VGs volume group but fails... which is not so strange as it
is an NFS volume:

The volume is actually mounted fine on the node:
