As for DRBD:MC the plan was that if you choose Filesystem as opposed to Filesystem + DRBD, the DRBD resource would not be created. Well it was forgotten, but should be easy enough to fix. There are couple of workarounds for that, one is to enter the block device like "/dev/drbd/by-res/ocfs2" in the block device field instead of choosing the DRBD resource. > > Does the mc lack support of real ocfs2 handling with controld/o2cb? > I was thinking about some kind of shortcuts for this, but at the moment it is not the most popular configuration. It should be possible to enter it, though.
