 Thanks for reply.

 When I ran following command

 tgtadm --lld iscsi --mode target --op show

 It hangs forever


So I guess the command to create the export probably hangs too, and
the greenthread in nova-volume never joins... which is maybe why you
didn't get a traceback?

Sadly I've not seen that before from tgt.

But I guess it sounds like tgt isn't installed/setup properly.
There's a number of things you could check, maybe try and restart the
service and watch syslog for errors.

Jay makes a good suggestion, about running the commands manually -
some understanding of what the volume-manager does to provision
volumes and expose them via iscsi would help you understand where
things break down.

You could also try to install iscsitarget.  If your os has packages
it's pretty painless, but there is a dkms - just uninstall/purge tgt
first.  Then try setting nova-volume to use iet as the iscsi_helper in
your conf/flags.

Good Luck,

I actually don't see any errors in the log file contents below (you can 
ignore the silly AssertionError thing about threading.pyc).


Perhaps you could try executing the underlying volume creation commands 
as root and see if you get any output or if things just hang? From what 
I can tell, those commands would be:


sudo lvcreate -L 1G -n volume-0001 nova-volumes
sudo tgtadm --op new --lld=iscsi --mode=target --tid=1 
--targetname=iqn.2010-10.org.openstack:volume-0001


Also remember that your nova-volumes volume group must have enough size 
in it to create this volume!


Best,
