Ok Thnaks for the answers!!
So... there is not a way to have to machines synchronized over WAN and
the two machines with the filesystem mounted in RW ?
Thanks

We have a simetrical VPN between two sites.
How does DRBD result in this type of environment?
I think that the best is "Protocol A" and Im looking for use DRBD-Proxy
for compression, or Openvpn + LZO.
Opinions?
The latency overhead - both DRBD and at the locking layer - will kill
the file system performance.
appart from that, with dual-primary you _MUST_ replicate syncronously,
thus: DRBD protocol C.
for (hopefully) obvious reasons.
I still have this idea of implementing a replication aware
cluster file system locking layer mode, where lock _requests_ would be
inserted into (or at least in order with) the replicated data stream, so
it could be replicated asynchronously in theory.
IFF it can be made to work, that is probably several manyears
developement, though -- roughly estimated ;)
