Hi, Most of it is described here: https://tracker.ceph.com/issues/22928 Buckets created under Jewel don't always have the *placement_rule* set in their bucket metadata and this causes Nautilus RGWs to not serve requests for them. Snippet from the metadata: { "key": "bucket.instance:pbx:ams02.446941181.1", "ver": { "tag": "86lc3iVtQpPiJYkh95YCTnhu", "ver": 2 }, "mtime": "2020-10-09 09:12:04.744423Z", "data": { "bucket_info": { "bucket": { "name": "pbx", "marker": "ams02.241978.4", "bucket_id": "ams02.446941181.1", "tenant": "", "explicit_placement": { "data_pool": ".rgw.buckets", "data_extra_pool": "", "index_pool": ".rgw.buckets" } }, "creation_time": "2014-02-16 12:32:15.000000Z", "owner": "vdvm", "flags": 0, "zonegroup": "eu", "placement_rule": "", Notice that *placement_rule* is empty and that this bucket has *explicit_placement* set. There is no way to update the bucket.instance metadata as far as I know, otherwise I could have set a placement rule for the bucket. Earlier on the ML this has been discussed: https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/thread/ULKK5RU2VXLF... People there compiled a manual version of RGW, something I'd rather stay away from. Has anybody seen this and if so: Have you found a solution? The commit that breaks these buckets is this one: https://github.com/ceph/ceph/commit/2a8e8a98d8c56cc374ec671846a20e2b0484bc75 14.2.0 was the first release with that code in there. So two things I'm thinking about and I don't know which one is best: - Update RGW and modify the if-statement added by commit 2a8e8a - Enhance 'bucket check --fix' to update the placement_rule if none is set for a bucket Any hints or suggestions?
