ietd (iscsitarget) - kernel module version mismatch

kermu · 16. März 2014

When I trying to run iscitarget service, this message appears:
root@KASZT-DEV25-NAS:/etc/init.d# /etc/init.d/iscsitarget status
iSCSI enterprise target is not running ... failed!
root@KASZT-DEV25-NAS:/etc/init.d# ietd -f -d 9
1394977712.151820: kernel module version mismatch!

Where I can get compatibile kernel or precompiled iscsi daemon (ietd) for my kernel from packageage iscsitarget ?

my kernel:
root@KASZT-DEV25-NAS:/etc/init.d# uname -a
Linux KASZT-DEV25-NAS 2.6.32-5-amd64 #1 SMP Mon Sep 23 22:14:43 UTC 2013 x86_64 GNU/Linux

modules and plugnin version:
root@KASZT-DEV25-NAS:/etc/init.d# dpkg -l |grep -i iscsi
ii iscsitarget 1.4.20.2-1 iSCSI Enterprise Target userland tools
ii iscsitarget-dkms 1.4.20.3+svn496-1 iSCSI Enterprise Target kernel module source - dkms version
ii iscsitarget-module-dkms 0.3 iSCSI Enterprise Target module for Linux
ii openmediavault-iscsitarget 0.5.5 OpenMediaVault iSCSI Enterprise Target plugin

Thanks for reply
Kris

Try to purge the plugin again including everything it installed, then reboot and try to install it again. The module was not compiled correctly against your kernel.

Just to help, everything means also dkms. I have done this:

Code

apt-get purge iscsitarget openmediavault-iscsitarget
apt-get purge iscsitarget-dkms iscsitarget-module-dkms
#just to be sure that all not needed things are done (nothing has been removed)
apt-get autoremove


#than install it again:
apt-get install  openmediavault-iscsitarget

It has recompiled kernel module to match backport kernel and it is working. I have now installed this:

Code

root@nas:~#  dpkg -l |grep -i iscsi
ii  iscsitarget                           1.4.20.2-1                     iSCSI Enterprise Target userland tools
ii  iscsitarget-dkms                      1.4.20.3+svn496-1              iSCSI Enterprise Target kernel module source - dkms version
ii  iscsitarget-module-dkms               0.3                            iSCSI Enterprise Target module for Linux
ii  openmediavault-iscsitarget            0.5.5                          OpenMediaVault iSCSI Enterprise Target plugin

I have this problem http://bugtracker.openmediavault.org/view.php?id=889. I have had working iscsi and than installed backport which broke my iscsi.

PS: When I have started writing this post I have strong believe in that not reinstaling dkms is the problem and its reinstaling will solve my problem. Problem remains. Please have a look at my last constole output and give me some advice what to try. Thanks.
