ceph-client.rgw.xxy-2f201r-ceph-s3-c1-01.rar - debug log as `radosgw-admin user stats` on slave (719 KB) Tave liu, 01/12/2018 01:42 AM

if you list the user's buckets on both sides, do you see the same results?

you can check `radosgw-admin sync error list` for errors on the specific user or their buckets

and it would also help to include the debug log (--debug-rgw 20 --debug-ms 1) of your `radosgw-admin user stats` command that fails on the secondary zone

list the user's buckets on both sides, list each bucket, all the results(bucket size, bucket objs) are correct:
master zone:

}

but, `radosgw-admin user stats ` is not error about some values on slave zone (as total_entries,last_stats_sync):
master zone:
[root@sx-3f3r-ceph-s3-c1-03 my-cluster]# radosgw-admin user stats --uid=Ymliu {
"stats": {
"total_entries": 118829,
"total_bytes": 11899758630,
"total_bytes_rounded": 12184944640
},
"last_stats_sync": "2018-01-11 09:41:10.394107Z",
"last_stats_update": "2018-01-11 10:11:14.170735Z"
}

slave zone:
[root@xxy-2f201r-ceph-s3-c1-01 ~]# radosgw-admin user stats --uid=Ymliu {
"stats": {
"total_entries": 123250,
"total_bytes": 12341758630,
"total_bytes_rounded": 12637552640
},
"last_stats_sync": "0.000000",
"last_stats_update": "2018-01-11 10:11:47.163477Z"
}

on both zone , `radosgw-admin sync error list` all error message was:
"error_code": 16,
"message": "failed to sync bucket instance: (16) Device or resource busy"
