Thanks for the reply Robert.

Version: 12.2.12 Luminous, using ceph-ansible containerised.

I was told that we're using a pre-luminous CRUSH format. I don't know if you can "migrate" or upgrade it to a Luminous based one?

Only thing I can think that means is no upmap support, but you don't need upmap. As long as you have the CLASS column, you can do the device classes.
