So, for now, I'm back to using 8.0.8. Another thing worthy of note is that when using 8.0.8, the part in rc.sysinit that mounts the udef file system just completes - in 2 seconds or so. When using 8.0.11 (no other changes, just updated the rpms and re-made the initrd with the new packages), it fails / times out. Since nothing else on the setup changes inbetween these attempts (I upgraded forward and backward a few times now just to make sure), it is a consistent problem. 8.0.8 works, 8.0.11 doesn't. Nothing of note in the logs, and /proc/drbd seems to be showing nothing wrong when the node actually finishes booting (which takes a lot of patience). The peer node is powered off and physically disconnected, so unless it's constantly trying to talk to it and timing out, I can't see why this is happening. 8.0.8 certainly doesn't do this. Gordan
