Hello, Two days ago, linbit made separate DRBD9 repository for Proxmox 5. I try to make DRBD9 cluster but doesnt work. Nodes can not add themselves in cluster. I follow all the instructions but cant do it. DRBD9 repository has drbd-dkms package which means that i have to download same version pve-headers with kernel release. I use pve no subscription repository. I test them in qemu Virtual Machines. Is there someone who can help me? Has someone tried, make a virtual infrastructure for testing? Thank you!
