corosync

[vicmar]

Hi,
i just installed a cluster with 3 nodes (with zfs raid), a couple days ago i started to see a disconnection of the nodes, and right now i need to restart the corosync service to make them reconnect.
Im newbie in proxmox, and do not encounter any log with a error and i dont know if its a configuration problem.

Thanks in advance.

Looks like multicast problems. Do you have a configured IGMP querier?
