That's a bug in the mysqld_multi script. You can fix this by fixing the
script.
A
while ! check_if_stopped ; do sleep 1 ; done
should suffice.
What is a bit surprising is that the Filesystem RA doesn't kill the
processes; it's supposed to at least try and in the normal course of
life, should succeed to. There's some cases where it can't (ie, open
references in-kernel which lsof/fuser can't find), but I wouldn't think
mysqld_multi triggers that ...
FWIW, if you were running a crm-style cluster, the failed stop would
escalate to a node fence and the cluster as a whole still be able to
proceed.
