both cluster are in the same epoch and period:
root@ceph-a-1:~# radosgw-admin period get-current
{
"current_period": "b7392c41-9cbe-4d92-ad03-db607dd7d569"
}
root@ceph-b-1:~# radosgw-admin period get-current
{
"current_period": "b7392c41-9cbe-4d92-ad03-db607dd7d569"
}
but the sync state is still "master is on a different period":
root@ceph-b-1:~# radosgw-admin sync status
realm 833e65be-268f-42c2-8f3c-9bab83ebbff2 (myrealm)
zonegroup 15550dc6-a761-473f-81e8-0dc6cc5106bd (ceph)
zone 082cd970-bd25-4cbc-a5fd-20f3b3f9dbd2 (b)
metadata sync syncing
full sync: 0/64 shards
master is on a different period:
master_period=b7392c41-9cbe-4d92-ad03-db607dd7d569
local_period=d306a847-77a6-4306-87c9-0bb4fa16cdc4
incremental sync: 64/64 shards
metadata is caught up with master
data sync source: 51019cee-86fb-4b39-b6ba-282171c459c6 (a)
syncing
full sync: 0/128 shards
incremental sync: 128/128 shards
data is caught up with source
