[Users] Ovirt 3.3.2 Cannot attach POSIX (gluster) storage domain

[Steve Dainard]

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.
