Hi Darren,
I figured out the issue. I ran into the following bug - https://bugs.launchpad.net/devstack/+bug/1072121.
Basically, the issue was an entry in the /etc/tgt/targets.conf file, which was causing "tgt-adm —update …" command to fail.
Thank you,
Ahmed.

Ahmed,
What errors can you see in cinder-volume.log when the volume creation fails?
The guide you refer to talks about creating a VG from a local file for testing purposes only. In a production setup you would create a VG using real disks/partitions. For cinder, the default vg name expected is cinder-volumes (this can be changed in cinder.conf). For nova-volume it was nova-volumes.
Thanks
Darren

John,
I verified step 13 in the Migrate twiki. Just curious, should I create the VG in a certain directory (e.g /var/lib/cinder/volumes).
Also, In the document "Openstack Deploy and Install manual", the steps for nova-volume recommend having a VG group called nova-volumes (created from a partition). However, the steps mentioned in ( http://docs.openstack.org/trunk/openstack-compute/install/apt/content/osfolubuntu-cinder.html ) creates a VG from a local file. Will be the recommend way to setup cinder service going forward. Just making sure I am not missing anything.

John,
I reboot my controller node, and things seem to be working a bit better. I followed the steps in "OpenStack Deploy and Install – Ubuntu", section Appendix B ( http://docs.openstack.org/trunk/openstack-compute/install/apt/content/osfolubuntu-cinder.html ). All the three cinder-api/volume/scheduler services are running.

I am attaching text file containing the log entries from the three cinder log files. Can you please help me understand why the volume creation is failing? I really appreciate your help.

Ahmed.

John,
Thank you for your response. When you stay start from scratch, do you mean re-install everything (all services) from scratch, as in a fresh install of Ubuntu? And then not install nova-volume and don't create endpoint for nova-volume?
Not to impose on you, but can you help me understand what does the following error mean:
ERROR: Malformed request url (HTTP 400) (Request-ID: req-8cff9608-598b-4618-bdc1-1068a1227781)
Is there an issue with how the REST command (Get/Put) is formed?
Is the service not listening on the expected port, or the service is not even up and running?
Regards,
Ahmed.

Hello,
I just installed installed cinder, however, I am getting the following error.

Can someone please help me understand what this error means. I don't see any logs being generated in any of the cinder log files - cinder–api.log, cinder-scheduler.log, cinder-volume.log.
Any pointers to debug this issue would be greatly appreciated.
Regards,
Ahmed.

Ahmed,
It looks like there's still a problem with your endpoint configuration? If your conf files are in fact set up correctly as advised earlier there is also a potential that you didn't clean up the nova-volume settings you had in keystone and the CS. Depending on your system, you might want to consider dropping the tables from your DB and starting from scratch and install cinder only.
Thanks,
John
Ahmed,
No... sorry, I didn't mean re-install the OS, just reconfigure OpenStack from scratch (drop the databases [NOT the mysql and other defaults]) and step back through the config without the nova-volume piece in the mix.
The malformed request is telling you that there's something that the receiving end does not like about the call you've made. The reason I suspect the endpoint or catalog service issue is that I've made the same mistake and seen the same error myself :)
Thanks,
John
Ahmed,
Sorry this has been so much trouble for you, it looks like the only thing missing now is your iscsi/tgt setup. Double check the items in step 13 on Migrate Wiki.

John
