[Linux-cluster] Cman tool leave remove, device or resource busy

[rhurst at bidmc.harvard.edu]

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
