I am currently attempting to configure a pair of load balancing servers in an Active/Active configuration using the following:

  1. Nginx
  2. Corosync
  3. Pacemaker

Applicable instructions were followed according to Clusters from Scratch.

However I do not know if the cluster is running in Active-Active configuration based upon the following crm_mon output. Any tips or advice would be greatly appreciated.
