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.

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.
