Hi Ansgar,
I've submitted the following PR to recover broken OMAPs:
https://github.com/ceph/ceph/pull/43820
One needs a custom build for now to use it though. And this might be a
bit risky to apply since this hasn't passed all the QA procedures...
For now I'm aware about one success and one failure stories of its
application. Perhaps it would be a good idea to make a DB volume backup
(via either raw disk copy or bluefs export) prior to trying it.
Thanks,
Igor

Hi fellow ceph users,
I did an upgrade from 14.2.23 to 16.2.6 not knowing that the current
minor version had this nasty bug! [1] [2]
we were able to resolve some of the omap issues in the rgw.index pool
but still have 17pg's to fix in the rgw.meta and rgw.log pool!
I have a couple of questions:
- did someone have done a script to fix that pg's we were only able to
fix the index with our approach [3]
- why is the 16.2.6 version still in the public mirror (should it not be moved)
- do you have any other workarounds to resolve this?
thanks for your help!
Ansgar
