2016-12-01 04:09:52 -0500 commented answer cinder-volume service is down

It turns out python-keystonemiddleware is already installed and this doesn't fix the problem

Could the problem be related to this error that stands out in the /var/log/cinder/cinder-volume log

CappedVersionUnknown: Unrecoverable Error: Versioned Objects in DB are capped to unknown version 1.11

I saw a similar problem here https://bugs.launchpad.net/openstack-manuals/+bug/1582133 (https://bugs.launchpad.net/openstack-...). But the host OS was RHEL 7.2. The solution accepted was to install python-keystonemiddleware package. Will try this and update.

cinder-volume service is down. I have been setting up my openstack environment for the Newton release following the documentation. My challenge is with getting the cinder-volume service to stay up and running. NTP is running (using chrony) and the cinder host is configured to synchronize with the controller. I have two disks on the node, sda and sdb. sda has normal partitioning that runs the underlying os (Ubuntu 16.04 LTS), sdb is configured as LVM with the volume group "cinder-volumes" with a size of 100GB. Any attempt to create a volume returns an error status (which is expected since cinder-volume service is not up).

Here's my cinder-volume log: /var/log/cinder/cinder-volume.log
