Cannot recreate a PCS resource after deleting a resource with the same name

Issue

• Using pcs, creating a resources with a given name (e.g. "VirtualIP"), then deleting it, prevents the creation of a new resource with the same name (e.g. "VirtualIP").

# pcs resource create VirtualIP ocf:heartbeat:IPaddr2 ip=192.168.0.99 cidr_netmask=32 nic=eth2 op monitor interval=30s meta is-managed=false

-> OK

# pcs resource delete VirtualIP
Deleting Resource - VirtualIP

-> OK

# pcs resource create VirtualIP ocf:heartbeat:IPaddr2 ip=192.168.0.99 cidr_netmask=32 nic=eth2 op monitor interval=30s meta is-managed=false
Error: unable to create resource/fence device 'VirtualIP', 'VirtualIP' already exists on this system
