DRBD 2 nodes syncer error proxmox 4.3

[JoanLl]

Hi,

I'm trying to set up a 2 node DRBD following this guide:

https://pve.proxmox.com/wiki/DRBD

DRBD configuration is mostly the same as the guide, just IP values have been changed. When I try to start DRBD I got an error:

SRV04:/etc/drbd.d# /etc/init.d/drbd start
[....] Starting drbd (via systemctl): drbd.serviceJob for drbd.service failed. See 'systemctl status drbd.service' and 'journalctl -xn' for details.
failed!

Looking at the log:

SRV04:/etc/drbd.d# journalctl -xn

A bug or I'm missing something?

Thanks,

I guess you are trying to setup drbd8.......that isn't support in PVE4........You need DRBD9 https://pve.proxmox.com/wiki/DRBD9

True, it's DRBD9 in PVE4

According to DRBD9 documentation, dual-primary mode is not supported in 9.0.x, it will be in 9.1.

I wanted to setup DRBD dual-primary mode to try live migration on a two node PVE cluster. I guess the only way to achieve it is to wait till DRBD's 9.1 release and later added to pve repositories.
