unless you pass the --sync-stats, the stats are synced only at a fixed interval iirc.

Yes, I know the stats are synced only at a fixed interval iirc.
But the question is, when I make a request of creating a same bucket, the stats became zero. Is the processing logic right?
In my opinion, when an user create a same bucket whitch he already own, the stats should not be changed to zero.
Don't you think it is a bug?

Hmm didn't know this, yeah that doesn't sound right

Thanks a lot. Can you backport the fixes to Jewel and Hammer ?

Once the pr gets merged in master, we can stage backports to older releases

This no longer happens in master (it still does in hammer).
We need to figure out what exactly fixed it and backport that

@Orit Wasserman: does it happen in jewel?

Possibly https://github.com/ceph/ceph/pull/9584? I'm still able to see the issue in master though

This problem always exists in v10.2.2。
The different is, when create same bucket in 10.2.2, the stats didn't become zero, but decreased.

[root@ceph01 ~]# radosgw-admin user stats --uid=jiaopengju {
"stats": {
"total_entries": 5,
"total_bytes": 1298938831,
"total_bytes_rounded": 1298939904
},
"last_stats_sync": "2016-09-10 02:51:13.131644Z",
"last_stats_update": "2016-09-10 02:51:13.130762Z"
}
[root@ceph01 ~]# s3cmd mb s3://jstat
Bucket 's3://jstat/' created

[root@ceph01 ~]# radosgw-admin user stats --uid=jiaopengju {
"stats": {
"total_entries": 4,
"total_bytes": 1194081231,
"total_bytes_rounded": 1194082304
},
"last_stats_sync": "2016-09-10 02:51:13.131644Z",
"last_stats_update": "2016-09-10 02:51:24.028592Z"
}

After query stats with using "radosgw-admin user stats --uid=jiaopengju --sync-stats", the stats go back to normal.

[root@ceph01 ~]# radosgw-admin user stats --uid=jiaopengju --sync-stats {
"stats": {
"total_entries": 5,
"total_bytes": 1298938831,
"total_bytes_rounded": 1298939904
},
"last_stats_sync": "2016-09-10 02:55:17.564786Z",
"last_stats_update": "2016-09-10 02:55:17.563847Z"
}

[root@ceph01 ~]# radosgw-admin user stats --uid=jiaopengju {
"stats": {
"total_entries": 5,
"total_bytes": 1298938831,
"total_bytes_rounded": 1298939904
},
"last_stats_sync": "2016-09-10 02:55:17.564786Z",
"last_stats_update": "2016-09-10 02:55:17.563847Z"
}

Howerver, when doing the operation "s3cmd mb s3://jstat " again, the stats go back wrong as above description.

I tried on latest master and cannot reproduce (I used s3cmd)
