KVM VM HA instructions fail at enabling DRBD service

[SoftNotWork]

The systemctl enable drbd step located here: https://docs.linbit.com/docs/linstor-guide/#s-proxmox-ls-HA

fails with the following error:

systemctl enable drbd Synchronizing state of drbd.service with SysV service script with /lib/systemd/systemd-sysv-install. Executing: /lib/systemd/systemd-sysv-install enable drbd update-rc.d: error: drbd Default-Start contains no runlevels, aborting.

The following package versions are installed onto the latest Proxmox:

dpkg --list|grep drbd ii drbd-dkms 9.0.21-1 all RAID 1 over TCP/IP for Linux module source ii drbd-utils 9.11.0-1 amd64 RAID 1 over TCP/IP for Linux (user utilities)

Any ideas where we're getting it wrong?

This was changed some time ago. If you want to go that route, you can enable the Default-Starts again. IIRC so far this was a warning (or an error one can ignore as the service is still "systemd enabled" afterwards). So I would check if the service is actually enabled and executed after a reboot.

root@serv1:~# systemctl status drbd.service ● drbd.service - DRBD -- please disable. Unless you are NOT using a cluster manager. Loaded: loaded (/lib/systemd/system/drbd.service; disabled; vendor preset: enabled) Active: inactive (dead)

If we compare that to SSH:

● ssh.service - OpenBSD Secure Shell server Loaded: loaded (/lib/systemd/system/ssh.service; enabled; vendor preset: enabled) Active: active (running) since Mon 2020-01-27 15:26:30 PST; 56min ago

Is this how it should be responding to the systemctl enable? It doesn't appear to be starting.

You can enable the drbd.service without and sysv "hack":

SYSTEMCTL_SKIP_SYSV=1 systemctl enable drbd

Its wokring for me...but is it the correct way to start the service on boot?

linstor controller HA was simplified and reworked as documented here: https://linbit.com/drbd-user-guide/linstor-guide-1_0-en/#s-linstor_ha

It does no longer need the drbd.service.
