Hello,
I have two servers with PROXMOX version 7.4 installed. The 2 servers have 2 internal disks each.
On both servers I configured the second disk of 1 TB with lvm.
Now I defined 2 VMs on the first node pve00 on the lvm disk (storage is not defined as qcow2 file but as piece of lvm) , how can I replicate all the configuration on the other node pve01.
It seems that drbd must be used.
But how can I configure ? How should be the host storage configuration of both nodes ?
On dashboard I don't see anything regarding replication of VM disks (see attachment).
Thanks

To use replication among cluster nodes you need ZFS [1]. You will need a QDevice to keep quorum if one host fails/is down [2], specially if you use HA to avoid node fencing [3].

DRBD isn't officially supported by Proxmox, although Linbit seems to support it. Also, PVE 7.4 is EOL and you should be using PVE 8.x.
