Fixed In Version: openstack-cinder-2013.2-0.12.rc2.el6ost
Doc Type: Bug Fix
Doc Text:
Cause: LVM versioning was not expected to contain strings while these could be used in custom builds of the LVM tools. Consequence: LVM version parsing, needed to ensure availability of Thin provisioning, was failing to initialize, causing openstack-cinder-volume service to not start. Fix: The parser now uses a regexp to inspect only the relevant digits. Result: LVM version is parsed correctly and openstack-cinder-volume starts as expected.
