2 Nodes cluster unicast problem?

[pblou]

Hi,

There is now some week, I have a problem with 2 nodes cluster (Proxmox 4.4-5)

When I reboot node 2, the cluster stop and say 'Quorum not ready' on node 1.

I think I have a unicast problem:

omping node1 node2
node1 : waiting for response msg

I have see that sometime, Node1 reboot too when I restart node2 !

This is normal, you need 3 nodes to have quorum.

if the other node reboot, maybe this is because you have enable HA ?

you need quorum to use HA, so you need 3 nodes minimum.

omping only test multicast.

Hi spirit,

yes I enable HA at installation but I don't use it. Did you know if I can disable it ? (I don't have have any vm in HA config).

I think Quorum can work with 2 nodes only for transfert offline VM.
