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,
Brent
