Comment 72 for bug 1569925

For now, the workaround for this bug is this:

inaddy@iscsihang:~$ sudo su -

# disconnect what iscsid has mapped
root@iscsihang:~$ iscsiadm -m node --logoutall=all

# disconnect all leftovers
root@iscsihang:~$ for file in `find /sys/devices -name *delete`; do echo 1 > $file; done

# shutdown
root@iscsihang:~$ shutdown -h now

(as long as you don't have iscsi root device)

Concentrating efforts in why systemd doesn't finish when iscsi connections and paths are online. Will check why (even recent version) open-iscsi looses track of connections if killed/restarted by a new login.
