Thanks, both. That’s a useful observation. I wonder what I can try to get accurate user
stats. All of our users are quota-ed, so wrong users stats actually stop them from
writing data. Since stats are only updated on write: I have some users who are inactive
and their stats are correct. I have other users who have been actively writing. I see
users who have up to 55 times the expected vs. actual size. I looped over buckets
manually via the Admin Ops API and pulled the stats for all of the user’s buckets and
summed these and compared that to the output from “radosgw-admin user stats"
I would guess that underflowing counters could be one explanation, but there may be other
things going wrong in the stats aggregation...
Thanks,
Liam

You can ignore rgw.none details, it dont make sense today from our experience
Still dont know why dev dont cleanup bucket with those rgw.none stats...
Some of our buckets got it others new ones no.

For example, here is a bucket that all of a sudden reports that it has
18446744073709551615 objects! The actual count should be around 20,000.
"rgw.none": {
"size": 0,
"size_actual": 0,
"size_utilized": 0,
"size_kb": 0,
"size_kb_actual": 0,
"size_kb_utilized": 0,
"num_objects": 18446744073709551615
},
That number is a small negative 64bit signed value, printed as an unsigned
64bit integer.
Seems like the counter underflowed.
2^64 = 18446744073709551616

May the most significant bit of your life be positive.
