Hi there,
I am dealing with this issue for a while, but could not figure out what is
going on.
After a reboot in the openstack server, I am not able to restart ANY instance
that had a nova-volume attached.
I tried the DR procedure here without any improvement:
http://docs.openstack.org/trunk/openstack-compute/admin/content/nova-disaster-recovery-process.html
The error in compute.log is:
ERROR nova.compute.manager [req-adacca25-ede8-4c6d-be92-9e8bd8578469

This is a very restrictive issue, because I can not simply attach volumes to
instances knowing that in a power failure or reboot for maintenance I will have
my instances unavailable.
Below there is some info about my setup.
Any idea? Anything!
:)
Linux nova-controller 2.6.32-279.11.1.el6.x86_64 #1 SMP Tue Oct 16 15:57:10 UTC
2012 x86_64 x86_64 x86_64 GNU/Linux
rpm -qa |grep openstack
openstack-nova-api-2012.2-2.el6.noarch
If you follow:
https://fedoraproject.org/wiki/Getting_started_with_OpenStack_EPEL
https://fedoraproject.org/wiki/Test_Day:2012-09-18_OpenStack#Setup_OpenStack_volumes
https://fedoraproject.org/wiki/QA:Testcase_Create_Cinder_Volumes
You get the note:
On RHEL based systems the config files in /etc/tgt/conf.d/ don't currently
honor globbing.
Only the main /etc/tgt/targets.conf seems does. So to avoid that issue causing
tgtd to not start:
sed -i '1iinclude /etc/nova/volumes/*' /etc/tgt/targets.conf
sed -i '1iinclude /etc/cinder/volumes/*' /etc/tgt/targets.conf
then restart tgtd:
service tgtd restart
Hopefully that will setup everything on boot.
thanks,
Pádraig.
