Just a wild guess, you haven't created the network interface associated.

Eg: for this resource to work:

primitive eth0.21HA ocf:heartbeat:IPaddr2 \
         params ip="" cidr_netmask="29" nic="eth0.21" \
         op monitor on-fail="restart" interval="10s"

You *must* have "ifup-ed" the eth0.21 iface before otherwise Pacemaker 
cannot apply the VIP because there is no iface. You can create eth0.21 
iface with fake IP such as ofc.

Quote of "sudo crm ra meta IPaddr2":

nic (string, [eth0]): Network interface
The base network interface on which the IP address will be brought online.

If left empty, the script will try and determine this from the routing 

Do NOT specify an alias interface in the form eth0:1 or anything here; 
rather, specify the base interface only.


*There must be at least one static IP address, which is not managed by 
the cluster, assigned to the network interface.*

If you can not assign any static IP address on the interface, modify 
this kernel parameter: sysctl -w net.ipv4.conf.all.promote_secondaries=1 
(or per device)
