ceph version 11.1.0-6147-g12706d7
(12706d76225fa1491d00362d3bc04e0541dead73)
A failure to repair occurred because without a digest in the object info
the code doesn't attempt to decide which omap is wrong. Here we only
have an omap_digest_mismatch error. Had the "selected_object_info"
included "od" presuambly of 1fff04c0 then "omap_digest_mismatch_oi"
would have been set on osd.47 and it would be repaired.
The way to fix this particular case is to stop osd.47, remove the object
with ceph-objectstore-tool, then restart osd.47 and the repair should
then re-create a correct object and omap there. As you can see the
object name is 100011cf577.00000000 in pool 1 (metadata).
