I don't know of a good way to repair inconsistencies automatically from within Ceph. However, I seem to remember someone saying that with BlueStore OSDs, read errors are attempted to be fixed (by rewriting the unreadable replica/shard) when they are discovered during client reads. And there was a potential plan to do the same if they are discovered during scrubbing. I can't remember the details (this was a while ago, at Cephalocon APAC), so I may be completely off the mark here.
