The answer is yes and using a distributed file system, such as Ceph, is the way to do it. Canonical's HA reference architecture is a great example as it uses Ceph to store a lot of the Openstack data.

This answer is very detailed, but the euca-authorize commands you gave only set up the security rules which masser said he already did. I am having the same problem. Where should we be making these checks and running these commands if we have all the services on separate machines?

2013-03-28 10:39:29 -0600 asked a question Using blade servers with attached storage for compute nodes

My question is similar to question 49 on this site, but not the same.

Background: We want to deploy Openstack on blade servers and use attached storage for ephemeral disks on the compute node. We also want to also deploy Cinder (volume storage) on a blade server in the same way, using attached storage also for persistent volumes.

I'm aware that you can specify LVM as the ephemeral disk (or image type) and specify the LVM group to be used (according to the Openstack documentation on nova.conf).

Question: Would we mount the attached storage as an LVM volume (in an LVM group) on the compute node host OS and then just specify that LVM volume using libvirt_images_volume_group=GROUPNAME in nova.conf?
