iscsi_trgt missing because can't build kernel module

Question

When attempting to start the iscsitarget service, I get

FATAL: Module iscsi_trgt not found.

Trying to build module using instructions from http://sourceforge.net/apps/mediawiki/iscsitarget/index.php?title=Unofficial_DEBs fails and the build log only has a single line in it saying the build started. Nothing about the failure.

Solution 1

It depends on your ubuntu-version.

On newer systems (since Maverick) you have to install some additional packets:

sudo aptitude install iscsitarget iscsitarget-source iscsitarget-dkms

This compiles the required module automagically.

On Lucid you have to compile yourself (and maybe again after every kernel-update):

sudo aptitude install iscsitarget iscsitarget-source
# compile with module-assitant
sudo m-a a-i iscsitarget

Solution 2

If none of the solutions are working, try following:

apt-get install --reinstall iscsitarget-dkms

This re-installs the iscsitarget dkms and resolved the problem for me.

Which ubuntu-version do you use?

[bumbling fool]

These are the instructions I had followed. The question is how to determine why the compile is failing.

The log-files can be found under /var/cache/modass. Have you tried the -t -v options (text-mode + verbose)?

In ubuntu 11.10 oneiric ocelot, installing above mentioned packages will automatically compile the required kernel modules and install it to the system. After that, you can run; sudo /etc/init.d/iscsitarget start to start the iscsitarget service. Hope this helps :)

@Sajith, This may be true in general, however the same package broke for me when upgrading from 10.04. I had to apt-get install iscsitarget-dkms to fix it then add the module manually. Not sure why. The above directions did fix it though. :)
