[Bug 1753098] [NEW] umountiscsi.sh - tries to umount all LVM filesystems

[HenningMalzahn]

Public bug reported:

On Ubuntu 16.04.4 LTS, all updates available installed, package open-
iscsi (2.0.873+git0.3b4b4500-14ubuntu3.4) I just ran into this bug:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=836135

This does only happens in case all nodes are set to manual start. The fix linked in the afore mentioned bug report solves this issue.
Changing any of the nodes to automatic startup everything works as expected.

In addition to the bug above the systemd open-iscsi.service fails to start as well in case all nodes are set to start manually.
The service use the following command on start:

/sbin/iscsiadm -m node --loginall=automatic

which returns with status code 21 (as outlined in the man page) in case
there's no node set to start automatically.

This also leads to the ExecStop operation

/lib/open-iscsi/logout-all.sh

to fail with return code 21.

To sum it up: It's not possible to start or stop the open-iscsi.service
properly having only manual nodes defined.
