in a test environment y desactivate drbd daemon for testing but with or without drbd daemon running, the problem persist I use the next handler and fencing policy in drbd fencing resource-and-stonith; outdate-peer "/sbin/obliterate-peer.sh"; Digimer when you suggest add "sleep 10"' is in drbd.conf?
