I've been trying to configure the cloud sync module to push changes to an Amazon S3 bucket without success. I've configured the module according to the docs with the trivial configuration settings. Is there an error log I should be checking? Is the "radosgw-admin sync status --rgw-zone=mycloudtierzone" the correct command to check status?

Thanks,

It turns out I can get it to sync as long as I leave "radosgw-admin --rgw-zone=aws-docindex data sync run --source-zone=default" running. I thought with mimic the sync was built into the ceph-radosgw service? I'm running version 13.2.4. I'm also seeing these errors on the console while running that command.

Additionally "radosgw-admin --rgw-zone=aws-docindex data sync error list --source-zone=default" is showing numerous error code 39 responses/

 "message": "failed to sync bucket instance: (39) Directory not empty"
"message": "failed to sync object(39) Directory not empty"

When it successfully completes I see the following

  metadata sync syncing
                full sync: 0/64 shards
                incremental sync: 64/64 shards
                metadata is caught up with master
      data sync source: af57fe9a-43a7-4998-9574-4016f5fa6661 (default)
                        syncing
                        full sync: 0/128 shards
                        incremental sync: 128/128 shards
                        data is caught up with source

When I stop the "data sync run" the status will just sit on 

      data sync source: af57fe9a-43a7-4998-9574-4016f5fa6661 (default)
                        syncing
                        full sync: 0/128 shards
                        incremental sync: 128/128 shards
                        data is behind on 1 shards
                        behind shards: [75]
                        oldest incremental change not applied: 2019-02-05 17:44:51.0.367478s

Thanks,
Ryan
