Do you know if the LVM backend is configured to use a dedicated block device on the storage node? Or might it be using a loopback device such how tooling like puppet-cinder handles things (see [1])? [1] https://github.com/openstack/puppet-cinder/blob/master/manifests/setup_test_volume.pp#L22 If the LVM backend uses a loopback device, then remember that loopback devices are not automatically restored on reboot. A common failure scenario is the storage node reboots, and the cinder-volume LVM backend does not come up because the LVM loopback device isn't restored.
