Description

Currently, there is no way for an OSD to detect erroneously missing objects in a pg collection. A scrub, therefore, if it detects an object present on the primary and missing on the replica does not have a way of knowing which filesystem is in error. One approach would be for the HashIndex mechanism to maintain some form of hash of each subdirectory's contents.
