I'm trying to create a vm in a single node cluster using ceph pool. But it's keep on throwing same error every time. vm comes into locked state and automatically abort the process of creating that vm. it won't create the vm.

Hi,
for Ceph, you need at least 3 nodes: https://pve.proxmox.com/pve-docs/chapter-pveceph.html#_recommendations_for_a_healthy_ceph_cluster

But i have 2 node cluster working fine with Ceph. Only for single node ceph cluster i'm facing this issue of unable to create vm.​

Ceph is not designed for this use case, but for high availability with at least three nodes. E.g. what if you'd lose one of the two nodes?
