You should make sure your cluster is in a healthy state before you do this, and be careful if there is already data in your storage pools affected by this change - you may cause inadvertent data migrations. Are you sure that you have enough space in your pool?

if your crush map change is working, you should be able to see it with "ceph osd tree". Just because the crush map was accepted doesn't mean that it is working in the way you want.

I would create a separate storage pool not used by openstack first, and assign it the crush ruleset, then test it with rados bench and make sure that data is flowing to the OSDs exactly as you expect. Only then should you try to move OpenStack pools.
