After above 2 files are set, the haresources is where we want to be to control Heartbeat's behaviour. This is an example for 1 Vserver that we will set up later on.

nano /etc/ha.d/haresources

node1 drbddisk::r1 LVM::drbdvg1 Filesystem::/dev/drbdvg1/web::/VSERVERS/web::ext3 vserver-web SendArp::123.123.123.125/eth0

The above will default the Vserver named web to node1 and specify the mount points, the vserver-web script will heartbeat start and stop it, the sendarp is for notifying the network that this IP can be found somewhere else than before. (Have added the SendArp an extra time below for better result.)

The vserver-web script is basically a demolished version of the original R2 style agent by Martin Fick from here: http://www.theficks.name/bin/lib/ocf/VServer. What I did is remove the sensible top part and replace "$OCF_RESKEY_vserver" with the specific Vserver name, also added an extra /etc/ha.d/resource.d/SendArp 123.123.123.126/eth0 start to the start part because I had various results when done by Heartbeat.
