What I have, samba 5.5 glusterfs ext3 ucarp. 1 PDC 2 BDCs running on
different places all vols are syncron by glusterfs.
What I had before, DRBD(master/master) gfs2 samba. Disadvantage no more than
two hosts possible. And be aware of DRBD getting corrupt.
In my case the whole production was dead. But I was lucky I could recover
from a backup.
Good Luck Daniel

In my company, we have 2
distant facilities, with people at each facility working on the same
files.
The 2 facilities are connected through MPLS with about
10MBytes/s BW.
Saving the work files to servers located at one or the
other facility has became a pain for the people accessing the files from
the remote site.
Trying to improve files availability, I was wondering
if a setup based on GPFS/GlusterFS plus samba for serving the file would
be a good reply to this problem.
If only 2 sites, and never more, DRBD+GFS2+Samba may be a good solution.
See: http://www.drbd.org/
With this setup all clients at both sites see the same filesystem (GFS2)
through Samba, but their file access is always to the local server's
disks. DRBD transparently mirrors the disk blocks between the two
servers.
I'd only consider this DRBD under two conditions:
1. If that MPLS pipe is rock solid all the time.
2. Workload is NOT writing many large say 100MB+ files regularly
