I"m reading this: https://www.digitalocean.com/community/tutorials/how-to-set-up-an-apache-active-passive-cluster-using-pacemaker-on-centos-7

and wondering... if webnode1 fails completely... how it would reallocate to webnode2? Everything was configured on webnode1 as the primary... maybe i've missed something in the tutorial.

Could this howto be followed where you use a third, in a different datacenter, to point to other servers (also in seperate datacenters)?
