Observed behavior:

• In an environment with bucket index sharding enabled, deletion of a bucket leaves behind the bucket index shards.

Desired behavior:

• When a bucket is deleted, all bucket index shards should be deleted.

Reproduction:

• Enable bucket index sharding:
  rgw_override_bucket_index_max_shards = 32
• Create buckets
• Delete buckets
• List contents of bucket index pool

Attempted deleting the bucket data with the following three methods, all with the exact same results:

# s3cmd del --recursive s3://bucket-to-delete
# radosgw-admin bucket rm --bucket bucket-to-delete  --purge-objects
# radosgw-admin user rm --uid user-to-delete --purge-data

Further, attempting to clean up with metadata rm does not help:

# radosgw-admin metadata rm bucket:default.538200.103

The deleted buckets do not show up with metadata list:

# radosgw-admin metadata list --metadata-key="bucket.instance" | grep default.538200.103 -c
0

But they do show up with rados ls:

# rados ls -p .rgw.buckets.index | grep default.538200.103 -c
32
