The cluster is just too small to do anything useful. It can be used to learn Ceph but really not for much more. Erasure Coding needs a lot of CPU, this is usually achieved with a large number of nodes (more than 10) and a proportional number of OSDs. Mixed HDDs and SSDs in one pool is not good practice as a pool should have OSDs of the same speed.
