We use pacemaker to start/stop VEs and to be sure they only run on one
node. Anyway crashes happen periodicly. We have about 40 VEs distributed
between both nodes, some with high disk I/O
We had GFS before and we will have to return to it, but we wanted to know
about other OCFS2 installations.

Thanks and regards.
