I have one user bucket, where inexplicably (to me), the bucket takes an
eternity to list, though only on the top level. There are two
subfolders, each of which lists individually at a completely normal speed...
eg (using minio client):
[~] % time ./mc ls fried/friedlab/
[2018-09-26 16:15:48 CDT] 0B impute/
[2018-09-26 16:15:48 CDT] 0B wgs/
real 1m59.390s
>
[~] % time ./mc ls -r fried/friedlab/
> ...
real 3m18.013s
[~] % time ./mc ls -r fried/friedlab/impute
> ...
real 0m13.512s
[~] % time ./mc ls -r fried/friedlab/wgs
> ...
real 0m6.437s
The bucket has about 55k objects total, with 32 index shards on a
replicated ssd pool. It shouldn't be taking this long but I can't
imagine what could be causing this. I haven't found any others behaving
this way. I'd think it has to be some problem with the bucket index, but
what...?
I did naively try some "radosgw-admin bucket check [--fix]" commands
with no change.
