Hi,

We have an unicast setup with corosync v1.4.2 which is unable to reload 
it's configuration file, and want to add a new node.

Our plan is to enable maintenance mode in pacemaker and restart corosync 
at the nodes one by one, then disable maintenance mode. We have just 
VirtualDomain and stonith resources. Is it a working method to add a new 
node so that the services (resources) are not interrupted?

Is there a better way to add a new node without downtime in this 
configuration?

Best regards,
Jozsef
