iscsitarget will not compile

I can confirm the same bug.

root@storage1:~# uname -a
Linux storage1 2.6.24-14-server #1 SMP Wed Apr 2 04:16:40 UTC 2008 i686 GNU/Linux
root@storage1:~#

My system is up to date (apt-get update && apt-get upgrade)

I found that the bug also exists in Debian, see: http://groups.google.com/group/linux.debian.bugs.rc/browse_thread/thread/7abd26b18e75d7a1/3eec332d63e0100d?lnk=gst&q=iscsitarget#3eec332d63e0100d

The version shipped by Ubuntu: 0.4.15-5ubuntu2

I got it working under Hardy by downloading the newest source from the IET website.

I extracted iscsitarget.tar.bz2 in /usr/src and replaced the "kernel" and "include" directory with the directories in the latest version from the IET website.

This is how i did it:

apt-get install iscsitarget-source
cd /usr/src
wget http://dfn.dl.sourceforge.net/sourceforge/iscsitarget/iscsitarget-0.4.16.tar.gz
tar -xzf iscsitarget-0.4.16.tar.gz
tar -xjf iscsitarget.tar.bz2
cd modules/iscsitarget/
rm -r include/ kernel/
cp -a /usr/src/iscsitarget-0.4.16/kernel .
cp -a /usr/src/iscsitarget-0.4.16/include .
cd /usr/src
tar -cjf iscsitarget.tar.bz2 modules
m-a a-i iscsitarget

I know this is not THE best way, since i download a new version of IET, but it fixes it for me.

FYI, i am running the Ubuntu Hardy Beta1

Ok, this works, but the files /proc/net/iet are not created!

The iSCSI servers runs and you can discover it and log on to it and use it, but the files in /proc are not created.

I even tried the source code from Debian, it compiles, but the files in /proc are created either.

Ok, i figured it out!

In the package "linux-ubuntu-modules-2.6.24-14-server" the iscsi_trgt.ko module is also shipped, but this one is broken.

When you remove the directory "/lib/modules/2.6.24-14-server/ubuntu/block/iscsitarget" en run "depmod -ae" you can compile the iscsi_trgt.ko module like i described above.

This will place the module in "/lib/modules/2.6.24-14-server/kernel/drivers/iscsi" after wich you can start the IET software.

Now the files "/proc/net/iet/volume" and "/proc/net/iet/session" will be created and the IET server will run as expected.

But i am wondering:
- Why is the iscsi_trgt.ko module shipped in linux-ubuntu-modules-2.6.24-14-server and also available to be compiled from source?
- For DRBD you can only install the utils, but the kernel module is already pre-compiled by Ubuntu.

Why is this done this way, a matter of miscommunication?

Hi,

Can you try from https://edge.launchpad.net/~zulcss/+archive,

You will need to put the following in your /etc/apt/sources.list

deb http://ppa.launchpad.net/zulcss/ubuntu hardy main
deb-src http://ppa.launchpad.net/zulcss/ubuntu hardy main

And then sudo apt-get update.

Thanks
chuck

Hi chuck,

That works, the targets builds correctly...

But i was wondering, why is the iscsi_trgt module also supplied in linux-ubuntu-modules? The module supplied by this package is loaded instead of the module build by iscsitarget-source, wich leaves you with a non-working iSCSI Target.

Shouldn't this be corrected?

Ill look into it

Ack from me, just make it work zul.

Applied Chuck's patch to iscsitarget

Ok, but to be sure. When hardy comes out, do you need to compile the target software (kernel module) or can you use the module shipped with the kernel?

This bug was fixed in the package linux-ubuntu-modules-2.6.24 - 2.6.24-16.21

Ok, just to be sure:

Compiling the module manually is not needed anymore when using the server edition?

Hi,

I get the same error above. I've been loosely following this guide;

http://computing.dwighthubbard.info/index.php/2007/12/10/setting-up-a-computer-system-with-ubuntu-linux-to-act-as-an-iscsi-san-storage-array-for-linux-and-vmware-clients/

A bit lost now :(

Hi Dan,

Please read the complete bug report. A fix has been commited and will be available soon.

Hi,
I get the same error as on topic.
