Hello,
I recently moved a bucket from 1 cluster to another cluster using rclone. I
noticed that the source bucket had around 35k objects and the destination
bucket only had around 18k objects after the sync was completed.
Source bucket stats showed:

When I checked the source bucket using aws cli tool it showed around 18k
objects. The bucket was actively being used so the 18k is slightly
different.
> aws --profile mimir-prod --endpoint-url https://my.objectstorage.domain
> s3api list-objects --bucket mimir-prod > mimir_objs
> cat mimir_objs | grep -c "Key"
> 18090
I did a check on the source bucket and it showed a lot of invalid
multipart objects.

So I tried to run `radosgw-admin bucket check --check-objects --bucket
mimir-prod --fix` and it showed that it was cleaning things with thousands
of lines like

but the end result shows nothing has changed.

Does this command do anything? Is it the wrong command for this issue? How
does one go about fixing buckets in this state?
Thanks!
