Backport #14142
Updated by Abhishek Varshney over 8 years ago
https://github.com/ceph/ceph/pull/7080 If a user accidentally creates a pool snapshot on an RBD pool, images can no longer be snapshotted. There is no way to recover w/o recreating the pool. Update the docs to warn of this behavior and optionally add a test to allocate/release a self-managed snapshot when this is the first image in a pool. Allow this check to be bypassed via a config setting.
