hi, i've installed a ceph multi site setup with two ceph clusters and each one radosgw. the multi site setup was in sync, so i tried a failover. cluster A is going down and i've changed the zone (b) on cluster b to the new master zone. it's working fine. now i start the cluster A and try to switch back the master zone to A. cluster A believes that he is the master, cluster b is secondary. but on the secondary is a different period and the bucket delta is not synced to the new master zone: root@ceph-a-1:~# radosgw-admin sync status realm 833e65be-268f-42c2-8f3c-9bab83ebbff2 (myrealm) zonegroup 15550dc6-a761-473f-81e8-0dc6cc5106bd (ceph) zone 51019cee-86fb-4b39-b6ba-282171c459c6 (a) metadata sync no sync (zone is master) data sync source: 082cd970-bd25-4cbc-a5fd-20f3b3f9dbd2 (b) syncing full sync: 0/128 shards incremental sync: 128/128 shards data is caught up with source 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 how can i force sync the period and the bucket deltas? i've used this howto: http://docs.ceph.com/docs/master/radosgw/multisit e/ br Kim _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
