Hi,
I just trying to setup 4 nodes cluster(meantime without HA), which was not problem after reading wiki. I want ask about nodes synchronisation which creates big amount of traffics on our network infrastructure.
I definitely dont expect such a multicast storm as its lead to sucessfully DOS our main router. In some topics here on forum its recommendet to use dedicated network or network card.
So how should I proceed? Just create brigde(vmbrX) from second network card(which was not use during installation) and create separate subnet for use with pvecm to create nodes links...whats the recommendation?

thx

The cluster communication does not send much data, so what do you mean by 'multicast storm'?

Well, I did more testing and it looks like something wrong with one of nics on board. I didnt use this one before proxmox install, so this would be the real source of my problem, no cluster setup. Anyway thx.
