I've not made my mind up on that. But thanks for that warning! Maybe GFS2 is

Sorry for being unclear! The goal is to have a redundant, high-available file
server. I'd like both my boxes to share the same data and being able to failover
in case one of them dies. DRBD+CLVM seemed to be a most reasonable solution. My
question was indeed not in the line of my original question. I was just wondering
how to make this storage accessible to other nodes in the network. iSCSI seems to
be the preferred solutions. But maybe I should ask these questions on the linux-ha
