You have been subscribed to a public bug:
when using open-iscsi and multipathd for a mpio setup there are several
init script logical issues:
when shutting down, the system does first stop multipathd and then try
to umount the filesystem and then stop open-iscsi to the system hangs
forever on shutdown.
Killing the daemon shouldn't have direct impact on umount of the map,
unless all the paths for that map go offline. If every operation goes in
parallel (with my understanding of the new gen init services like upstart
and systemd), and iscsi sessions get dropped before the umount, yes, you
definitely will run into the hang situation.
Again, the hang situation depends on how your multipath policy is
configured.
also when booting up it does mount the partition before multipathd and
open-iscsi are ready and you get the ubuntu screen that the partition
could not get mounted, do you want to skip.
after bootup process you can however mount the partition without any
issue.
It is hard to make out what might be the cause from just the english
explanation. Perhaps the multipath maintainer here can translate this to *Steps
To Reproduce* and then investigate it further.
