Error EINVAL: pool size is smaller than the crush rule min size

            }
        ]
    }
]

There is no `--size` param as there is for `ceph osd pool create`. The default size however doesn't seem to be between 1(min_size) and 10(max_size) for whatever reason.

Hi Joshua,

I tried on the master and it works for me. The HEAD was at 240c46a75a44cb9363cf994cb264e9d7048c98a1 dated "Sat Sep 19 11:36:43 2020 +0200"

Warning! This feature is experimental.It may cause problems up to and including data loss.Consult the documentation at ceph.com, and if unsure, do not proceed.Add --yes-i-really-mean-it if you are certain.
