[rdo-users] Creating CRUSH placement rules with TripleO

[Cody]

Hi everyone,

Is it possible to define CRUSH placement rules and apply to different
pools while using TripleO to deploy an overcloud with Ceph
integration?

I wish to set the "vms" pool to use SSDs and "volumes" pool to use
HDDs. On a pre-existing Ceph cluster, I can define CRUSH placement
rules using device-class and apply the corresponding rules when create
pools. But, I don't know how to do so with TripleO.

Could someone shed light on this?

Best regards,
Cody
