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
