Doc Text: |
With /var/lib/nova/instances on shared storage the Nova image cache manager may corrupt the checksum files or checksum redundantly or it may incorrectly delete images determining them as unused.
This bug is fixed in Nova Folsom release, and in Essex this feature should be disabled by removing parameter remove_unused_base_images = True from nova.conf and adding image_cache_manager_interval = 0 when using shared storage for Nova VM images.

So this bug has been fixed in Folsom stable, and we have the config tweak in our essex fedora branch so it's just a matter of making sure we cherry pick this to the RHOS essex branch, as I believe it does not warrant a full backport. Note that pushing an update with changed nova.conf won't fix existing installations where nova.conf was customized b/c it's %config(noreplace) Moving to 2.1 |
