I think the interface didn't get sync from other carp interface,
so it doesn't know that he is the MASTER or BACKUP, and because
of that goes into the INIT state.
Setup at least 2 interfaces like in this example and try it out.
Example
So on cluster1 put this in rc.conf
######## NETWORK ###############################################
defaultrouter="10.0.0.1"
hostname="cluster1.somehost.net"
ifconfig_bge0="inet 10.0.0.101 netmask 255.255.255.0"
ifconfig_bge1="inet 192.168.0.1 netmask 255.255.255.0"
cloned_interfaces="carp0"
network_interfaces="carp0 pfsync0 bge0 bge1 lo0"
ifconfig_carp0="vhid 1 pass ugly_password 10.0.0.103/24"
ifconfig_pfsync0="up syncif bge1"
pfsync_enable="YES"
pfsync_syncdev="bge1"
################################################################
on cluster2 put this in rc.conf
######## NETWORK ###############################################
defaultrouter="10.0.0.1"
hostname="cluster2.somehost.net"
ifconfig_bge0="inet 10.0.0.102 netmask 255.255.255.0"
ifconfig_bge1="inet 192.168.0.2 netmask 255.255.255.0"
cloned_interfaces="carp0"
network_interfaces="carp0 pfsync0 bge0 bge1 lo0"
ifconfig_carp0="vhid 1 pass ugly_password advskew 100 10.0.0.103/24"
ifconfig_pfsync0="up syncif bge1"
pfsync_enable="YES"
pfsync_syncdev="bge1"
