quorum problem, creating cluster

[Jeroen Kerkhof]

Dear,

We try to create a cluster, when we add the second node, we receive the following errors:


From the web interface: cluster not ready - no quorum?
From command line where we created the cluster on:

Quorum information

When we tried to at the new node to the cluster it was stuck on Waiting for quorum...

Most likely, multicast is not working (see https://pve.proxmox.com/wiki/Multicast_notes)

We had a similar issue when we upgraded our data center to ciscos relatively new Nexus line of switches. Nodes would join the cluster for about 2 mins then fall offline.

Adding "ip igmp snooping querier x.x.x.x" to vlan 1's config fixed the issue. Even more bizarre we had to specify a random IP in the vlan-config command. If a nodes IP was used that node would lose communication after 2 mins.
