Proxmox DRBD strange issue noticed on initial sync.

[Liam]

So I've got my cluster up and drbd seems to be working fine with one exception.

I have 2 resources, and I have r0 set for the 10.0.13.0 (10.0.13.101 and 10.0.13.102 respectively) and I have r1 set for the 10.0.12.0 network.
Now eth2 is on 10.0.12.* and eth3 is on 10.0.13.*.

Now here's where the weirdness comes in. All my drbd sync traffic is happening over eth2 while eth3 is seeing none regardless of which resource is being used.
This is on the latest version of Proxmox.

If anyone has any ideas or needs anymore info from me, please chime in.

What is your subnet mask?

What is your subnet mask?

You sir, are brilliant. I just noticed I failed to change it from the example. Set now to 255.255.255.0 and all is working well.

Thank you
