1. Because the value is automatically calculated is better to increase the value "retransmits_before_loss_const" (or decrease the "token" value) than to set a constant (200 milliseconds for example)?
Well... as I said in my scenario, I just add the line token with the value 200. I'm afraid I lack the proper knowledge to go deeper. 2. If I alter this value and in the future a node will be added/removed, the value will remain the same or it will be recalculated? Yes! The corosync.conf in /etc/pve will be sinc to any new server add to the cluster, via pmxcfs.
