[ClusterLabs Developers] Pacemaker & corosync - how does totem token works and formula

[Vicki Chen]

Hi,

I'm a software developer currently researching how Corosync utilizes the Totem protocol token. Corosync employs the Totem protocol to monitor the health of cluster nodes by circulating a token among them. If a node doesn't receive the token within a specified timeout period (configured in corosync.conf), it's considered unresponsive. I'm interested in diving deeper into this mechanism. Is there a specific formula or method used to determine host failure detection time in Pacemaker? Could you provide details? Thanks!

best regards,

Vicki Chen
