I still think they are not part of the cluster somehow. "ceph osd status" shows most likely they are not used. When you add just 1 osd you should see something in your cluster capacity and some rebalancing. Status of ceph is HEALTH_OK?
Thanks for the prompt reply.
Yes, it does. All of them are up, with the correct class that is used by the crush algorithm.

Hello guys, Let's say I have a cluster with 4 nodes with 24 SSDs each, and a single pool that consumes all OSDs of all nodes. After adding another host, I noticed that no extra space was added. Can this be a result of the number of PGs I am using?
I mean, when adding more hosts/OSDs, should I always consider increasing the number of PGs from a pool?
ceph osd tree
shows all up and with correct weight?
