[Linux-cluster] Problem adding a GNBD fence device

I'm using conga (Luci -> Cluster -> Nodes -> Properties) and I'm trying
to add one "Main Fencing Method"

Fence Type: GDBD
Name: data-partition
Servers (whitespace separated list): hotsite-1.company.com
IP Address:

When I click on "Update main fence device" I got this error:

	The following errors were found:
	An unknown fence device type was given: "gnbd."

Shared Fence Devices:
	Shared Fence Devices for Cluster: hotsites
	Agent type: Global Network Block Device
	Name: data-partition
	Nodes using this device for fencing:
	* No nodes currently employ this fence device

I need to add this fence-device one-by-one on my cluster or it's OK
using only a "shared" device?

That's the conf generated:
<?xml version="1.0"?>
<cluster alias="hotsites" config_version="9" name="hotsites">
