Description

I was looking at the "ceph --format=json status" pgmap bytes_{used,avail,total} values with the goal of using them to produce pretty graphs of historical usage.

The values didn't make any sense to me though. Digging a little deeper reveals:

    f->dump_unsigned("bytes_used", osd_sum.kb_used * 4096ull);
    f->dump_unsigned("bytes_avail", osd_sum.kb_avail * 4096ull);
    f->dump_unsigned("bytes_total", osd_sum.kb * 4096ull);

(4096 instead of 1024)
