Re: Strange USED size

Hi,

did you delete lots of objects recently? That operation is slow and ceph takes some time to catch up. If the value is not decreasing post again with 'ceph osd df' output.

Regards,
Eugen


Zitat von Marcelo <raxidex@xxxxxxxxx>:

Hello. I've searched a lot but couldn't find why the size of USED column in
the output of ceph df is a lot times bigger than the actual size. I'm using
Nautilus (14.2.8), and I've 1000 buckets with 100 objectsineach bucket.
Each object is around 10B.

KiB         0        36 GiB

Does anyone know what are the maths behind this, to show 18GiB used when I
have something like 1 MiB?

Thanks in advance, Marcelo.
