Greetings,
first of all I am not sure if this is the right place to post user
questions about targetcli. If not, please point me in the right direction.
To the problem now. I'm on opensuse 12.3 64-bit, while all kernel
modules seem included I had (as stated by documentation) to download and
build targetcli myself. Here I believe something is or went wrong. While
targetcli starts without any errors or warnings the object-tree seem
incomplete. For instance, from examples in the documentation I see when
starting targetcli it says
Using ib_srpt fabric module.
Using qla2xxx fabric module.
Using iscsi fabric module.
Using loopback fabric module.
This never happens, nor are any of those nodes available to configure.
Furthermore I believe I read, when starting targetcli it should via
rtslib fire up the modules needed, that does not happen either.
From what I can tell, OpenSuse incorrectly switched to the bogus
upstream version of rtslib on PYPI here: (CC'ing hare + saschpe)
https://build.opensuse.org/package/view_file?expand=1&file=python-rtslib.changes&package=python-rtslib&project=openSUSE%3AFactory
This version has since been removed from PYPI, and is/was not compatible
with the upstream targetcli either..
So, I'd recommend removing the default rtslib-2.1.fb27 package, and
installing rtslib.git + lio-utils.git from git.risingtidesystems.com
instead.
hare & saschpe, can you remove this version from the OpenSuse repo's,
and include the correct upstream, please..?
Hi Nicholas and thank you for looking into this.
Sorry I should have mentioned that I did install both rtslib and
configshell from git as well. Tried now just-to-test and installed the
rts-library from opensuse repositories and with that targetcli does not
start..

You'll want to build the rtslib RPMs for this.. Just doing setup.py
installs the python code, but not the fabric specs in rtslib.git/specs
to determine the active fabrics that should go into /var/target/fabric/
Hmmm... I honestly thought I had done everything by the book, apparently
not.
I have now built and installed the rpm-package and you are absolutely
right, the modules now load and the tree looks complete.
Nicholas, you're an absolute star!
Many thanks from
Jonas
