Package: open-iscsi
Version: 2.0.874-5
Severity: normal

Dear Maintainer,

when rebooting the system waits 50 seconds to synchronzize a disconnected
iSCSI drive:

[  464.538835] systemd-shutdown[1]: All filesystems unmounted.
[  464.538881] systemd-shutdown[1]: Deactivating swaps.
[  464.543864] systemd-shutdown[1]: All swaps deactivated.
[  464.548880] systemd-shutdown[1]: Detaching loop devices.
[  464.554513] systemd-shutdown[1]: All loop devices detached.
[  464.575951] kvm: exiting hardware virtualization
[  464.576045] sd 0:0:0:1: [sda] Synchronizing SCSI cache
[  473.818361]  connection1:0: ping timeout of 5 secs expired, recv timeout 5, 
last rx 4295008175, last ping 4295009472, now 422
[  473.824605]  connection1:0: detected conn error (1022)
[  525.274120] sd 0:0:0:1: [sda] Synchronize Cache(10) failed: Result: 
hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK
[  525.306298] reboot: Restarting system

If before rebooting I execute

sudo umount -f /mnt/iscsi
sudo iscsiadm -m node -T iqn.2000-01.de.xypron:odroid-c2 -p 192.168.0.1:3260 
--logout
sudo reboot

this waiting time does not occur.

Looking at the /lib/systemd/system/open-iscsi.service it seems that we already
try to logout before shutdown. So it seems unclear what makes the difference.

Below you will find that reportbug tried to read /etc/iscsi/iscsid.conf.
As this file contains passwords it is only accessible to root. Do you
need any information out of it for the analysis?

Best regards
