I don't see a need to remove the STATUSFILE at all, as that may
(and as you observed it) prevent the filesystem from stopping.
Perhaps to skip it altogether? If nobody objects let's just
remove this code:
758 if [ -f "$STATUSFILE" ]; then
759 rm -f ${STATUSFILE}
760 if [ $? -ne 0 ]; then
761 ocf_log warn "Failed to remove status file ${STATUSFILE}."
762 fi
763 fi
Cheers,
