I have read a couple of threads about duplicate inodes. And like Dan said [1] "The developer at that time suggested some manipulations to remove the omap entries for the older version of the inode from the stray dirs, and also to eventually run cephfs-data-scan scan_links." But ... in your log the object id is not printed "mds.0.cache.dir(0x100) _fetched badness: got (but i already had) [inode 0x600 [...2,head] ~mds0/stray0/ auth v10386" I would have expected the object right after ~mds0/stray0/. So I'm unsure how to find the right omap entry to delete. Gr.
