In the this configuration, I believe the failover hosts should be set to nonfailover hosts:

mdsfailover_HOST=${mds_HOST}
ostfailover_HOST=${ost_HOST}

This will allow the recovery tests to do simulated failover by ummounting and and mounting the targets on the same node to trigger Lustre recovery.
