Thats what I'm trying to do too, and those were exactly my worries. I
know that it might work with NFS, but I want something more flexible,
so I'm looking into distributed filesystems.

The problem is that I'm not satisfied with daily or hourly rsnapshot
backup, I want to have the replica as close to the original as
possible. We now replicate using DRBD but it introduces high latency
and it becomes really messy once you have more than 2 nodes (ganeti
might help with this, but it was pretty imature on RHEL last time I
looked). 

One alternative is also lsyncd but the real deal would be a real
distributed file system where everything happens in the background.
