[ceph-users] What is ceph doing after sync

Hi, I deployed a multi-site in order to sync data from a cluster to anther. The data is fully synced(I suppose) and the cluster has no traffic at present. Everything seems fine. However, the sync status is not what I expected. Is there any step after data transfer? Can I change the master zone to my new zone? Can I stop the old cluster? sudo radosgw-admin sync status realm bde4bb56-fbca-4ef8-a979-935dbf109b78 (cn) zonegroup d25ae683-cdb8-4227-be45-ebaf0aed6050 (beijing) zone 313c8244-fe4d-4d46-bf9b-0e33e46be041 (newzone) metadata sync syncing full sync: 0/64 shards incremental sync: 64/64 shards metadata is caught up with master data sync source: f70a5eb9-d88d-42fd-ab4e-d300e97094de (oldzone) syncing full sync: 1/128 shards full sync: 0 buckets to sync incremental sync: 127/128 shards data is behind on 14 shards behind shards: [3,21,42,54,55,62,71,75,92,95,104,106,108,122]
