Description

The following actions will create an unremovable RBD snapshot:

  1. Clone an image from an origin snapshot
  2. Flatten the clone
  3. While flattening, snapshot the clone
  4. Delete the origin snapshot and image

Result:

  • The new snapshot appears in rbd snap ls, but rbd snap rm fails with rbd: failed to remove snapshot: (2) No such file or directory.
  • rbd ls -l on the pool will segfault.

This bug was previously reported here and is still present in 0.87.1. The attached script demonstrates the problem.
