Hi Robert,
A colleague and I ran into this a few weeks ago. The way we managed to
get access back to delete the bucket properly (using radosgw-admin
bucket rm) was to reshard the bucket.
This created a new bucket index and therefore it was then possible to delete it.
If you are looking to get access back to the objects, then as Eric
said there's no way to get those indexes back but the objects will
still be there in the pool.
sudo radosgw-admin bucket reshard --bucket={bucket_name} --num-shards {number}
If you are doing multi-site replication, resharding can cause some
issues on earlier versions of ceph so check that out if that applies
to you. If you're just going to delete the bucket anyway it may not be
an issue.
Regards,
Richard

This was useful back when resharding did not automatically remove the older bucket index shards (which it now does), which had a different bucket_id from the current bucket index shards.
