Then the question is if
a) you'd want to integrate those Ubuntu servers into an existing Ceph cluster
(managed by Proxmox) or
b) if you just want to use a separate Ceph cluster in your Proxmox setup where
that Ceph cluster is based on your Ubuntu hosts.
Case a) is probably a bad idea due to (possibly) different Ceph versions
between Proxmox and Ubuntu.
Case b) should work without problem given the Ubuntu based Ceph cluster has the
correct options configured. [1] and [2] should
help in that case. Unfortunatelly I cannot provide the correct options, I can
only give you a dump of my PVE 4.4 based setup:
