I *think* the rotational flag isn't used at OSD creation time, but rather each
time the OSD starts to select between options that have _hdd and _ssd values.
If I'm mistaken, please do englighten me.
One can use a udev rule to override the kernel's deduced rotational value

Hi Michael,
yes, at least I'm interested. I also plan to use dm_cache and would like to
hear about your continued experience.
I have a few specific questions about your set-up:
- Sizing: Why do you use only 85G for the cache? Do you also deploy OSDs on the
remaining space on the NVMe or is it
