Hey folks,
quick (I hope) question: On my 3-node cluster I am swapping out all the
SSDs with fewer but higher capacity ones. So I took one node down
(maintenance, stop), then removed all SSDs, set up a new RAID, set up
lvm and gluster, let it resync. Gluster health status shows no unsynced
entries.
Uppon going from maintenance to online from ovirt management It goes
into non-operational status, vdsm log on the node shows:

I assume due to the changed LVM UUID it fails, right? Can I someone
fix/change the UUID and get the node back up again? It does not seem to
be a major issue, to be honest.
I can see the gluster mount (what ovirt mounts when it onlines a node)
already, and gluster is happy too.
Any help is appreciated!
