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

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:
