I have a ~2000 user mailcluster on a rbd blockdevice backed by ceph, it?s
distributed over ~8 disks and works without any issues for more than 3 years
now. Ceph is not so fast as DRBD but more flexible. I would not expect any
issues with DRBD, except for the problem that logical failures (e. g. an
accidental rm -rf /va/rmail) means your cluster is dead, whereas with dsync
nothing is lost.
