hi boris, We hit an issue late last year that sounds similar to what you are experiencing. I am not sure if the fix was backported to nautilus, I can't see any reference to a nautilus backport so it's possible it was only backported to octopus (15.x), exception being red hat ceph nautilus. https://tracker.ceph.com/issues/47866?next_issue_id=48255#note-59 https://www.mail-archive.com/ceph-users@xxxxxxx/msg05312.html Basically, a read request on a s3/swift object that took a very long time to complete would cause the associated rados data objects to be put in the GC queue, but the head object would still be present. So the s3 object would still show as present, `rados bi list` would show it (since head object was present) but the data objects would be gone, resulting in 404 NoSuchKey when retrieving the object. raf On Wed, 21 Jul 2021 at 18:12, Boris Behrens <bb@xxxxxxxxx> wrote: > Good morning everybody, > > we've dug further into it but still don't know how this could happen. > What we ruled out for now: > * Orphan objects cleanup process. > ** There is only one bucket with missing data (I checked all other > buckets yesterday) > ** The "keep this files" list is generated by radosgw-admin bukcet > rados list.
