[ceph-users] rgw squid - reshard stale-instances in multisite environment

Hi, we have a multisite environment, which only syncs metadata. Today I checked radosgw-admin reshard stale-instances list which brought up 29k entries. I've checked some randomly and those bucket_ids don't exist anymore. Is there a way to clean it up, or do I just leave it there and ignore it? I always read that this should not be touched in multisite environments. Cheers Boris
