Followup:
I eventually gave up trying to salvage the bucket. The bucket is supposed to have ca. 110000 objects, every attempt to "bucket index check --fix" increased that number by 110000, so something is very wrong.
Also, deleting the bucket with "radosgw bucket rm --purge-objects" failed with a "no such file or directory" error.
Even the biggest shovel I found could not remove the bucket:
# radosgw-admin bucket rm --bucket=XXXX --purge-objects --inconsistent-index --yes-i-really-mean-it --bypass-gc
2017-12-08 11:56:15.020617 7f799c326c40 -1 ERROR: could not drain handles as aio completion returned with -2
2017-12-08 11:56:16.879316 7f799c326c40 -1 ERROR: unable to remove bucket(2) No such file or directory
As the application relies on the bucket name, which is now occupied by this mystery bucket, I seem to be stuck. How can I remove this bucket?
Thanks

Hi all!
Apparently, one of my buckets went wonko during automatic resharding, the frontend application only gehts a timeout after 90s.
After an attempt to fix the index using “radosgw-admin bucket check –fix”, I tried to reshard id (6,3GB of data in ca. 230000 objects).
The resharding command is now running for over an hour. No significant load on any of the 18 OSDs, the host running radosgw-admin or on one of the three radosgw hosts. The OSDs are beefy machines with HDDs for Data and SSDs for index pools. Running 12.2.2.
How long should the resharding take? For a few minutes, radosgw-admin seems quite busy, but now it seems to only sit there at only a few % of CPU usage.
“radosgw-admin reshard list” reports an empty list. Reshard status reports

{
"reshard_status": 1,
"new_bucket_instance_id": "c2ffcb0f-a9a3-4360-a9be-5edef965449a.6860125.1",
"num_shards": 10
}
]
I have a feeling that the bucket index is still damaged/incomplete/inconsistent. What does the message
*** NOTICE: operation will not remove old bucket index objects ***
*** these will need to be removed manually ***
mean? How can I clean up manually?
Thanks,
Martin
