We ran into this issue as well and just patched a fix into our
distribution.  Basically, the patch will re-establish iSCSI connections
anytime an instance is hard rebooted.  The Nova configuration option
"start_guests_on_host_boot" ultimately results in executing the same code
as a hard reboot, which is why we opted to patch it into that function.

I've attached a copy of the patch to my response, which should apply
cleanly to stable/essex.  I'm planning to submit the patch upstream, since
I do not see a fix for it anywhere, even in Folsom.

Please let me know if this fixes the issue for you.

Subject: [Openstack] Manually attaching iSCSI volume to an instance

Hi,

I believe I am a "victim" of this bug:
https://bugs.launchpad.net/nova/+bug/1001088  ( I can not seem to find the
fix that was committed )

After rebooting my volumes are not restored and they become stuck in the
"in-use" state.

Is there a way to manually restore the volumes?  Using tgt-admin I
verified that the target exists, I used iscsiadm to login, and verified
that created a device node.  Here is a log showing what I just mentioned:
http://paste2.org/p/2101666

And here is a document I created showing my general setup, including
nova.conf.  (I didn't include glance, or keystone configs because they
seem to be working fine):

Any help would be greatly appreciated.  Thanks, Sam
