Linux Microknoppix #21 SMP PREEMPT Sat Jul 23 09:48:39 CEST 2011 i686 GNU/Linux

modprobe iscsi_trgt 

results in

FATAL: Module iscsi_trgt not found.

so did a

# apt-get install module-assistant debhelper


# m-a a-i iscsitarget

Fails with error

I've done most of the work of creating a new partition, volume group, etc..., here is a rough guide to what I've done so far:

Boot to UBCD, open partition manager, resize partition so there is some free space

create a new partition, but no formatting type /dev/sda3

boot back into linux root shell

aptitude install iscsitarget iscsitarget-modules-`uname -r`

First we set up the target (server2): Open /etc/default/iscsitarget...

vi /etc/default/iscsitarget

... and set ISCSITARGET_ENABLE to true:


root@Microknoppix:/sbin# vgcreate vg0 /dev/sda3
No physical volume label read from /dev/sda3
Physical volume "/dev/sda3" successfully created

Volume group "vg0" successfully created

now create 75GB lun under vgo named storage_lun1

root@Microknoppix:~# lvcreate -L75G -n storage_lun1 vg0
Logical volume "storage_lun1" created

vi /etc/iet/ietd.conf - add the following lines to file vi /etc/iet/ietd.conf

Target iqn.2001-04.com.example:storage.lun1
IncomingUser user p@ssw0rd
Lun 0 Path=/dev/vg0/storage_lun1,Type=fileio
Alias LUN1
#MaxConnections 6

root@Microknoppix:/dev/vg0# vi /etc/iet/initiators.allow

add to end of file:


/etc/init.d/iscsitarget start 
error Starting iSCSI enterprise target service: FATAL: Module iscsi_trgt not found.

So did an: apt-get install module-assistant debhelper

then: m-a a-i iscsitarget (which also installed kernel headers)

I'd like to get my win7 ultimate box at to connect to the target lun but here is where I am stuck.

not sure if this is related, but I have a server running as a iscsi target server, and after upgrading Ubuntu to the latest hardware stack, I can no longer access my remote disks. reinstalling/recompiling the driver also fails.. here is my question on askubuntu askubuntu.com/questions/511990/… –  RapidWebs Sep 1 at 15:59
maybe a bug report is in order? i'll take my issue to the ubuntu IRC channel and see if I can make any headway sometime. If I come up with anything, I'll post back here –  RapidWebs Sep 1 at 16:00

Get the latest version from SVN because the one in Debian and Ubuntu usually fails to compile. I had the same error and the latest-greatest compiles like charm.

svn co https://svn.code.sf.net/p/iscsitarget/code/ iscsitarget

Or you had better to use SCST, because it is more stable.
