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

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

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
