Yes, engine will let you use such volume in 3.5 - this is a bug. In 3.6 you will
not be able to use such setup.

replica 2 fails in a very bad way when one brick is down; the
application may get
stale data, and this breaks sanlock. You will be get stuck with spm
that cannot be
stopped and other fun stuff.

You don't want to go in this direction, and we will not be able to support that.

We need the whole file.

I suggest you file an ovirt bug and attach the full vdsm log file
showing the timeframe of
the error. Probably from the time you created the glusterfs domain.
