[intrepid] Can not stop iscsitarget

[Christian Roessner]

Binary package hint: iscsitarget

I have a very trivial iscsitarget setup:

cat /etc/ietd.conf
# iscsi target configuration
#

Target iqn.2008-09.de.roessner-net:storage.disk0
 IncomingUser iscsitest XXXX
 OutgoingUser iscsitest XXXX
 Lun 0 Path=/dev/vg01/lv_iscsi,Type=fileio

/etc/init.d/iscsitarget stop
Removing iSCSI enterprise target devices: succeeded.
Stopping iSCSI enterprise target service: succeeded.
Removing iSCSI enterprise target modules: FATAL: Module iscsi_trgt is in use.
failed.

Expected normal stop

[rhalff (rhalff)]

I can confirm the same with a similar configuration

[Stefan Bader (smb)]

Currently investigating some missing bits compared to previous versions. I will put in some updates as soon as those have been resolved.

[Tuomas Jormola (tjormola)]

I can confirm this also. I had a working iSCSI target setup with hardy. Also very simple configuration, no authentication or anything special, just some LVM2 LVs exported as blockio. But after upgrading to intrepid, it stopped working.

[Tuomas Jormola (tjormola)]

The Debian iscsitarget package version 0.4.16+svn162-2 (http://packages.debian.org/lenny/iscsitarget) seems to work fine. I downloaded the source package from a Debian mirror, created binary packages on the Intrepid system from the source, installed newly produced debs, compiled new iscsi_trgt module against linux-headers-2.6.27-7-server, replaced the stock Ubuntu iscsi_trgt module of linux-image-2.6.27-7-server with the new one, rebooted and the iSCSI service is now working again. Please upload fixed iscsitarget to intrepid-proposed. Thanks.

[Dustin Kirkland  (kirkland)]

I added a linux-image task.

It appears to me that the iscsi_trgt.ko provided by the Ubuntu kernel is buggy, and won't unload properly.

This is causing a nasty problem on package upgrade of iscsitarget in Jaunty (I'm working on the merge), because the initscript is "stopped" in the prerm, but this *always* fails if the module isn't unloaded.

:-Dustin

[Dustin Kirkland  (kirkland)]

Also, I just merged iscsitarget_0.4.16+svn162-2ubuntu1 for Jaunty.

But package upgrades will fail until we get the module unloading working properly.

As a workaround in the meantime in Jaunty, you can:
 $ sudo service iscsitarget stop
 $ sudo mv /etc/init.d/iscitarget /tmp
 $ sudo apt-get update
 $ sudo apt-get upgrade iscsitarget
 (Accept the package maintainer's new init script)

:-Dustin

[Dustin Kirkland  (kirkland)]

And using the new, Jaunty init script, module unload failures are reported by the init script, but are not FATAL. ie, they do not exit 1.

The updated iscsidriver has been added to Intrepid (not yet included in 10.20)
UBUNTU: iscsitarget: Update to official 0.4.16 driver
also one additional patch, since the driver from upstream fails to compile in Intrepid:
UBUNTU: Fix compile error after updating iscsitarget

[Steve Langasek (vorlon)]

Accepted into intrepid-proposed, please test and give feedback here. Please see https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

[Christian Roessner (christian-roessner-net)]

Can confirm: Update fixed the bug here

[Christian Roessner (christian-roessner-net)]

BTY: Please consider changes to the init-script, to load an optional /etc/default/iscsitarget. Because DAEMON_OPTS are missing, therefor a iscstarget may not be bound to a specific ip address. I do not want to open a new bug for such a little thing. Thx.

[Věroš Kaplan (veros-kaplan)]

Can confirm: bug fixed also on amd64.

[X.Y. (fixy67)]

I tried to use the proposed update but I didn't find the new version. I found only 0.4.15+svn148-2.1ubuntu2. (Currently I'm using intrepid amd64)
Is it my fault or something gone wrong?

[Steve Beattie (sbeattie)]

Sorry for the noise, I'd assumed there was actually a package in intrepid-proposed, based on Steve Langasek's comment. Is there going to be one? If not, please close out the intrepid task. Thanks.

[Stefan Bader (smb)]

The actual bug was part of the kernel source.

[Stefan Bader (smb)]

In Jaunty (current trunk) the iscsitarget code is 0.4.17.

[Stefan Bader (smb)]

In Intrepid the fix was released with 2.6.27-11.21.

[Stefan Bader (smb)]

Dustin, I am assigning the iscsitarget package task to you since I don't know the exact status.
