Trying that now. On a side note, the autodiscovery box is hard to edit.
So in the meantime, trying to up the version to take advantage of some
new features and ensure Gluster 6 is fully supported. Not having luck
with the oVirt UI upgrade at the moment ( Not a self hosted engine. It's
on a separate VM. ):

You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

Just upgraded to 4.3.5.
What do I do if I can't remove a host from a cluster? Maintenance
window options Active and Maintenance are grayed out. Host is currently
showing as Unassigned with an exclamation mark next to it. Items listed
include:
"Power Management is not configured for this Host. Enable Power Management"
"Gluster status is disconnected for this host. Restart Glusterd service"
"Host has no default route."
I try to modify some of this thinking maybe it will nudge the server out
of it's slumber but get this when trying to fix Power Management:
"Error while executing action:
mdskvm-p01.nix.mds.xyz:
Cannot edit Host. Host parameters cannot be modified while Host is
operational.
Please switch Host to Maintenance mode first."
Of course I can't put it into maintenance since it's grayed out.
Anyway to remove this host and start fresh?
