    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!

    They made the mistake to change license, but they have reverted their decision after a short amount of time but Proxmox never reconsidered DRBD9.
    As far as I know, drbd9 is the only way you could have a 2 storage node + 1 quorum node cluster, reducing a lot the cost of a HA solution.
    Also DRBD9 with 2 nodes looks far simpler/easier to manage than a 3 node ceph with osd, monitors etc..
    I think that DRBD9 brings to Proxmox much more advantages than Proxmox brings to Linbit, so I think they will never support properly proxmox.
    Any chance Proxmox will bring back DRBD9 technology for our poor that need very small (and ceaph) deployment of some sort of "redundancy"?
    Thanks in advance

    The chance of bringing it back is practically zero. Ceph is the future and the devs know it.

    Your comments does not make sense, DRBD9 has other case scenario where it is Practically better, reliable and cost effective solution, while Ceph has strict requirements, which makes it harder to implement in some cases.
