Hi Djahida
Since DRDB9 is technology preview with Proxmox , I would advise you to use another storage for your cluster.
If you have a small amount of hardware nodes, you can consider a big NFS server or ISCSI target for the shared storage and live migration of your VMs.
If you have many hardware nodes and a good network you can consider Ceph.

Hi Manu and thanks for the reply
I used DRBD with Proxmox 3, so I have more knowledges than NFS or ISCI target but I will test the NFS later
About my question, do you know if I have to enable the dual primary node on DRBD or not
