Proxmox cluster

[mad_morf]

Hi there. Sorry for my english.

I have a cluster with redundant corosync network.
May be i don't understand something.
When i do ifdown vmbr0 on the 3 node (0x00000003 1 192.168.1.226) - corosync works fine but, i can't access to webgui, it says no route to host.

When i connect to cluster via secondary subnet 192.168.42.0 and try to open 3 node, i get the same error.
Only when i connect directly to 3 node, i can reach it.
I understand that the cluster is trying to connect by primary ip.. but it's not logical, or not ?
Is there a way to fix this ?

Hi,

When the vmbr0 down is, can you ping the gateway?
Can you provide us with your network configuration `cat /etc/network/interfaces`
