Package: iscsitarget
Version: 1.4.20.2-10.1
Severity: important
Tags: upstream
Under heavy load the iscsitarget services fails to stop on module removal.
# service iscsitarget stop
[ ok ] Removing iSCSI enterprise target devices: :.
[ ok ] Stopping iSCSI enterprise target service: :.
[....] Removing iSCSI enterprise target modules: :FATAL: Module iscsi_trgt is
in use.
Changing etc/init/init.debian to use `rmmod --wait` instead of `modprobe -r`
corrects this issue.
This problem causes pacemaker to halt on failover to a secondary node when
using the lsb resouce agent
to control iscsitarget.
