Re: [Users] Ovirt 3.3.2 Cannot attach POSIX (gluster) storage domain
Hi Nir,
I have a thread open on the gluster side about heal-failed operations, so
I'll wait for a response on that side.
Agreed on two node quorum, I'm waiting for a 3rd node right now :) But in
the meantime or for anyone who reads this thread, if you only have 2
storage nodes you have to weigh the risks of 2 nodes in quorum ensuring
storage consistency, or 2 nodes no quorum with an extra shot at uptime.

According to sanlock and gluster log:
1. on the host, sanlock is failing write to the ids volume
2. on the gluster side we see failure to heal the ids file.
This looks like glusterfs issue, and should be handled by glusterfs folks.
You probably should configure sanlock log level back to the default by
commenting
out the configuration I suggested in the previous mail.
According to gluster configuration in this log, this looks like 2 replicas
with auto quorum.
This setup is not recommended because both machines must be up all the
time.
When one machine is down, your entire storage is down.
Check this post explaining this issue:
