I am building a small OpenStack cloud in my lab and had a few questions. I want to use OpenStack Ansible for the deployment. I have 5 physical servers each with >128GB and 2 XEON CPUs each with 24 Cores 3 of the 5 servers are currently running VMware ESXI managed by vCenter in a cluster. My questions: I want to use my remaining two servers as Nova compute hosts. Can the other remaining OpenStack services be installed on vm's running in my VMware environment? Would this be acceptable production? What would be a better solution if not? Can I separate OpenStack services and install them on th ..read more

I'm using Openstack Yoga. I created an instance with 400GB of disk, but after 60 retries the volume allocation had failed (now I've changed block_device_allocate_retries to 500 in nova.conf). I later deleted the failing instance but the associated 400GB volume would not be deleted. I tried to manually wipe the volume using commands: cinder reset-state --reset-migration-status VOLUME_ID cinder reset-state --attach-status detached VOLUME_ID cinder delete VOLUME_ID but the volume remained in the "deleting_error" state, so I followed this other procedure to delete the volume directly from the ..read more

There was a similar question asked a while back about images/glance, but this is different enough I thought it warranted its own thread. If I blow away and redeploy openstack and reconnect it to the same ceph cluster, is there a way to get cinder to know about/slurp in those existing volumes in the ceph cluster? I know the obvious way is to export the volume out of ceph, then upload it as a glance image on the new, freshly deployed openstack, done that loads of times before, but that seems silly to download and reupload to ceph essentially, given the volume is already sitting there in the vol ..read more
