Hi,

My lab setup two Ceph clusters as 2 zonegroups in a realm. Ceph version 16.2.13

As I know, if a bucket is created on secondary zonegroup, the master zonegroup
only know about its metadata, not data. So after resharding command is run
on master (to avoid inconsistent metadata), the bucket is synced back to
secondary which mean it will have no data, just like in master.

Is this a bug or I'm doing it wrong? Is there any other way to reshard a bucket in non-master zonegroup?
Thanks
