Hi Yehuda, Thanks for you help. No, listing does not work, if I remove the old index objects. I guessed, I could use the resharding for my purpose. I just tried * copy the index object * rewrite bucket metadata * reshard => I get new index objects at the old place. Metadata gets turned back again. Maybe this is more complicated as expected?

You didn't miss much. There is a guard in the code that prevents you from modifying the placement pools. I have this commit that changes that (but that probably doesn't help you much): https://github.com/yehudasa/ceph/commit/0baebec32e388f4cb7bdf1fee9afe2144eeeb354 The way to go forward for you I think would be by reshrding the buckets, which will put the bucket indexes in the correct place. Can you actually list the bucket indexes right now?
