I haven't had any files in a state of being healed according to either of
the 3 storage nodes.

I shut down one VM that has been around awhile a moment ago then told it to
start on the one ovirt server that complained previously.  It ran fine, and
I was able to migrate it off and on the host no issues.

I told one of the new VM's to migrate to the one node and within seconds it
paused from unknown storage errors no shards showing heals nothing with an
error on storage node.  Same stale file handle issues.

I'll probably put this node in maintenance later and reboot it.  Other than
that I may re-clone those 2 reccent VM's.  maybe images just got corrupted
though why it would only fail on one node of 3 if image was bad not sure.
