Corosync 3 fail over on proxmox 6

[pena]

Hi!

We are currently implementing a secondary 2 link for corosync and when reading the documentation it says that the secondary ring (ring with lower priority) wont see any traffic unless all higher priorities have failed.

# cat /etc/pve/corosync.conf
logging {
  debug: off
  to_syslog: yes
}

nodelist {
  node {
    name: pve-01
    nodeid: 1
    quorum_votes: 1
    ring0_addr: 10.100.0.xxx
    ring1_addr: 10.200.0.xxx
  }
  node {
    name: pve-02
    nodeid: 2
    quorum_votes: 1
    ring0_addr: 10.100.0.xxx
    ring1_addr: 10.200.0.xxx
  }
  node {
    name: pve-03
    nodeid: 3
    quorum_votes: 1
    ring0_addr: 10.100.0.xxx
    ring1_addr: 10.200.0.xxx
  }
}

quorum {
  provider: corosync_votequorum
}

totem {
  cluster_name: pve_cluster01
  config_version: 6
  interface {
    linknumber: 0
  }
  interface {
    linknumber: 1
  }
  ip_version: ipv4
  secauth: on
  version: 2
}

In our case we the have majority of our servers connected to one switch which is used by primary ring and I was wondering in the case that the switch goes down for maintenance, shouldn't corosync secondary link become the active link for the cluster?

Looking forward for your response.

Thanks!

It should, why are you asking?

We are about to test the link failover by:

# Test 1 - shutdown 2 of the links of the primary , connection should failover to secondary ring
# Test 2 - shutdown 2 of the links of the primary ring and 1 of the secondary, connection should failover to secondary ring

But when reading the official document it mentions that only when all links of the primary fail the connection will fail over.

Since lower priority links will not see traffic unless all higher priorities have failed

I guess that has to be applied per node.

I should test and see. I will provide an update
