Bug #24505
closedradosgw-admin user stats are incorrect when dynamic re-sharding is enabled
0%
Description
On a Ceph cluster started with vstart:
MON=1 OSD=1 MDS=0 MGR=1 RGW=1 ../src/vstart.sh -n -o "bluestore_block_size = 5000000000000" -o "rgw_enable_usage_log = true"
Using COSBench S3 workload - complete writing 1 million objects of 1KB --
<work type="prepare" workers="4" interval="5" rampup="5" config="content=zero;cprefix=s3cosbench;containers=r(1,1);objects=r(1,1000000);sizes=c(1)KB" />
although "ceph df" shows 999999 OBJECTS
POOLS: NAME ID USED %USED MAX AVAIL OBJECTS default.rgw.buckets.data 6 954 MiB 0.02 4.4 TiB 999999
radosgw-admin user stats shows only 272721 entries :
$ ./bin/radosgw-admin user stats --sync-stats --uid=testid 2018-06-12 08:06:24.588 7fa2f6410800 0 check_bucket_shards: resharding needed: stats.num_objects=272721 shard max_objects=100000 { "stats": { "total_entries": 272721, "total_bytes": 272721000, "total_bytes_rounded": 1117065216 }, "last_stats_sync": "2018-06-12 12:06:24.590311Z", "last_stats_update": "2018-06-12 12:06:24.586702Z" }
(Note the line above - "2018-06-12 08:06:24.588 7fa2f6410800 0 check_bucket_shards: resharding needed: stats.num_objects=272721 shard max_objects=100000")
Trying with adding the "--reset-stats" parameter did not remedy:
$ ./bin/radosgw-admin user stats --reset-stats --uid=testid { "stats": { "total_entries": 272721, "total_bytes": 272721000, "total_bytes_rounded": 1117065216 }, "last_stats_sync": "0.000000", "last_stats_update": "2018-06-12 12:08:15.044129Z" }

Adding another scenario -
where the cluster was installed with resharding and then resharding was disabled and radosgw restarted in the middle of cosbench write operation
resulting in the following condition:

Mark, have we addressed any of these issues in recent stats work?

Thanks for the quick reproduction procedure in #27205
Those bugs seem related, I will debug.
