Using the install of drbd off the suse enterprise 9 sp1 cd, i'm getting

Anyone know what might be causing this?
My config file:
resource webdrbd {
protocol C;
incon-degr-cmd "halt -f";
startup {
degr-wfc-timeout 120;
}
disk {
on-io-error detach;
}
syncer {
rate 100M;
group 1;
al-extents 257;
}
on web1 {
device /dev/nb0;
disk /dev/sda3;
address 192.168.1.111:7788;
meta-disk internal;
}
on web2 {
device /dev/nb0;
disk /dev/sda3;
address 192.168.1.112:7788;
meta-disk internal;
}
Thanks,
Nathan
