[ceph-users] classes crush rules new cluster

It looks like it is not possible to create crush rules when you don't have harddrives active in this class. I am testing with new squid and did not add ssd's yet, eventhough I added class like this. ceph osd crush class create ssd I can't execute this ceph osd crush rule create-replicated replicated_ssd default host ssd Is there any way around this?
