Description Samuel Just 2016-02-05 20:09:11 UTC

How reproducible:


Steps to Reproduce:
1. Produce unfound objects (see the ceph-qa-suite tests which do this)
2. Run client writes (like rados bench)
3. Run mark_unfound_[delete|revert]

Actual results:

Sometimes, an osd crashes.

Expected results:

The objects are either reverted or removed.
