Hi Mauro, I think you can create a data pool on ceph first and then add it as a storage pool in CloudStack with a storage tag and then create specific compute/disk offering with that storage tag to force VM's root disk and data disks to be deployed on the specific Ceph pool where erasure coding was configured.

We can do it mannually setting this comand at ceph: rbd create --size 20G --data-pool Pool-ISA Pool-ISA-Replicado/94a5650f-a67f-4375-a051-d906a0dbd466 But it can be great that cloudstack do this internally Did you ever use erasure coding with ceph?.
