i have a small poc cluster deployed openstack with ceph using juju.
now i would like to test add new servers with ceph-osds having ssds.
1.during initial deployment i used hdds for ceph osds.
2.now if i add new server with ssds by running command juju add-unit ceph-osd that may add these ssds to existing pools(i am not sure) and i may not able to see pure ssds performance.
3.so i would like to add new nodes having ssds as a ceph-osds to new pool by some name like ssdpool and would like to create a new vm with this pool
so now cinder should have 2 backends for vms creation one which came by default cinder-ceph before adding new nodes and one after adding new nodes ssdpool
4.please let me know how i can do this by using juju.
