There's a very serious known issue with the image cache cleanup code when you're using shared storage:
https://bugs.launchpad.net/nova/+bug/1078594
The fix is invasive and risky, but there's a known workaround (i.e. disable the image cache manager) which Vish has documented in the release notes.
We may just disable the image cache manager by default for the release.
Not may, but must because release note is not enough to cover possible data loss, even if in specific configuration. If https://review.openstack.org/#/c/16726/ is not merged, then we need alternative patch setting image_cache_manager_interval default to 0
