Description of problem: Attempt to attach a volume to a nova instance fails with the following error in the nova-compute log: 'iscsiadm: Could not login to [iface: default, target: iqn.2010-10.org.openstack:volume-81d30c1d-a932-4e03-babe-c8584bcc45ed, portal: 192.168.0.6,3260].\niscsiadm: initiator reported error (8 - connection timed out)\niscsiadm: Could not log into all portals\n' Version-Release number of selected component (if applicable): openstack-nova-compute-2012.2-0.7.f3.fc18.noarch How reproducible: 100% Steps to Reproduce: 1. Create a volume 2. Attach the volume to an instance 3. Monitor the volume status through 'attaching' back to 'available' Actual results: The volume status fails to reach 'in-use'. Expected results: The volume status transitions to 'in-use'.
The issue turns out to be that the iSCSI target was never actually getting created We need tgtd to include volumes configurations from /var/lib/nova/volumes as described here: http://lists.fedoraproject.org/pipermail/cloud/2012-July/001593.html
Small correction, it should include /var/lib/cinder/volumes in the tgtd.conf, i.e.: sudo sed -i '1iinclude /var/lib/cinder/volumes/*' /etc/tgt/targets.conf

FYI - for this to work on F17, you need this scsi-target-utils update: https://admin.fedoraproject.org/updates/FEDORA-2012-14471/scsi-target-utils-1.0.24-4.fc17
Re-opening as the work-around: # 1. remove non-globbed conf fragments sudo rm /etc/tgt/conf.d/{nova,cinder}.conf # 2. ensure that target config in /etc/cinder/volume picked up # after tgtd restart sudo sed -i '1iinclude /etc/cinder/volumes/*' /etc/tgt/targets.conf is still required. #2 in particular required to ensure that a volume created before a tgtd restart is still usable afterwards.
It seems nested includes as discussed in bug #643302 is supported, but nested globbing is not. Investigating.
This recent patch - https://review.openstack.org/12542 - is actually a part of the confusion here We didn't have this patch during the first test day and volume attach was failing However, in the second test day, this patch was in and attach works fine without any inclusion targets.conf The problem is that if you restart tgtd without the targets.conf inclusion, the targets disappear - this is the issue that the persistent targets work in Folsom was intended to fix
Possible solution detailed at bug 643302#c14
