[ceph-users] Re: Undo "radosgw-admin bi purge"

A PR that adds experimental support for restoring a bucket index was merged into main. It’ll need back ports to reef, quincy, and pacific. https://tracker.ceph.com/issues/59053 Currently it does not work

[ceph-users] Re: Undo "radosgw-admin bi purge"

Off the top of my head: 1. The command would take a bucket marker and a bucket names as arguments. It might also need some additional metadata to fill in gaps. 2. Scan the data pool for head objects that refer to that bucket marker. 3. Based on the number of such objects found, create a bucket

Everything you say is to be expected. I was not aware `reshard` could be run when the prior shards are removed, but apparently it can, and it creates new bucket index shards that are empty. Normally `reshard` reads entries from the old shards and copies their data to the new shards but since

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

[ceph-users] Re: Undo "radosgw-admin bi purge"

When the admin runs “bi purge” they have the option of supplying a bucket_id with the “--bucket-id” command-line argument. 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
