Is there any Swift command to know if replication task is completed after rebalance? After ring rebalance (adding new device to the ring), the replicator moves data around to fit new map. So how can I check the graceful completion of this task?
Have a look at swift-recon: http://docs.openstack.org/developer/swift/admin_guide.html#cluster-telemetry-and-monitoring
This will give you some hints about the last replication tasks: # swift-recon -r =============================================================================== --> Starting reconnaissance on 5 hosts =============================================================================== [2013-07-08 13:19:01] Checking on replication[replication_time] low: 0, high: 1, avg: 1.3, total: 6, Failed: 0.0%, no_result: 0, reported: 5 Oldest completion was 2013-07-08 10:30:14 (48 minutes ago) by 192.168.1.5:6000.
