Hello,

I've read in the DRBD9 manual that the connection between nodes must be "full mesh".
So for a three nodes cluster, we have to use 2 dedicated links on each node directly connected the other nodes.

In the proxmox drbd9 wiki page, I only see 1 dedicated connection per node in the three nodes example.

Did I missed something?

Thanks for your help
 
Hi,
this is more a performance thing, no requirement.
The only effect is you have lees speed.
 
Ok, thank you for the answer.
I guess i'll go for 2 bonded dedicated links for each node.
It will be the same for three nodes but leave me the opportunity to extend my DRBD9 cluster without the need to add NIC on each node.

Regards
 
To be clear you have to have a dedicated network for the DRBD storage only.
Outer way you get errors in the cluster communication.
