then I add the master zone to zonegroup 'zg2', and want to update the period, it return error as bellow:

[root@c49 ceph]# radosgw-admin period update --commit
2016-08-24 09:04:16.723669 7f3fcf632980 0 zonegroup zg2 missing zone for master_zone=
couldn't init storage provider

other op which needs to call RGWStoreManager::get_storage function is return error too with the same reason as above(e.g. restart a rgw daemon)
