Yes, I think it is DRBD 0.8 that has this where you can mount both sides
simultaneously. We are only using DRBD 0.7 right now and I'm looking to
see if GlusterFS may be a more capable solution for us. Looking for
better scalability. I've never had to work with the underlying devices
in DRBD. Worse case I just forced a full sync. And I'm hoping that is
the case with GlusterFS.

You can work with the underlying filesystem, say, to fix a problem,
but you'd want to work with it the way GlusterFS would, at least for
consistency. So, if it's a mirror, any change you make on one, you'd
want to reproduce on the other.
With drbd, you could only have one mounted at any given time;
otherwise, even mounting the other one would be something of a
catastrophe. Note that this isn't true of recent, bidirectional drbds,
if you run GFS.
Thanks,

Avati,
Yes, of course, it works. So it is similar to DRBD where you must
only interact via the exposed mounts and never directly to the
underlying subsystem.
