Interesting. Please paste full `ceph osd df tree`. What is actually your
NVMe models?
Yes, our HDD cluster is much like this, but not Luminous, so we
created as separate root with SSD OSD for the metadata and set up a
CRUSH rule for the metadata pool to be mapped to SSD. I understand
that the CRUSH rule should have a `step take default class ssd` which
I don't see in your rule unless the `~` in the item_name means device
class.
Indeed, this is a device class.
And new crush rule may be created like this `ceph osd crush rule
create-replicated <rule_name> <crush_root> <failure_domain>
<device-class>`, for me it is: `ceph osd crush rule create-replicated
replicated_racks_nvme default rack nvme`
