Unfortunately, we have run into the same issue... but we have found that a small pause before shutting cman down works every time (script snippet below -- sleep 1 was dicey, sleep 2 always worked, sleep3 just because):
service rgmanager stop [ $? -eq 0 ] || exit service gfs stop [ $? -eq 0 ] || exit service clvmd stop [ $? -eq 0 ] || exit service fenced stop [ $? -eq 0 ] || exit # invoking cman too early sometimes fails ... -t option too small? sync sleep 3 [ "$ACTION" = "leave" ] && service cman stop leave || service cman stop [ $? -eq 0 ] || exit service ccsd stop [ $? -eq 0 ] || exit On Mon, 2007-10-22 at 14:05 -0600, Josh Gray wrote: > I see in the FAQ the proper way to leave a cluster is with 'cman_tool leave > remove' I am getting a 'device or resource busy' error when I do that even > with GFS mounts removed and stopped.
