DRBD Parse error: got 'incon-degr-cmd' (TK 282) on CentOS - linux

Question

Setup
I currently have two NFS servers. And the plan is that they mirror their data to each other in realtime using DRBD and monitor each other using heartbeat.
This is my current /etc/drbd.d/t0.res config.
resource t0 {
protocol C;
incon-degr-cmd "halt -f";
startup {
degr-wfc-timeout 120; # 2 minutes.
}
disk {
on-io-error detach;
}
net {
}
syncer {
rate 10M;
group 1;
al-extents 257;
}
on node1 {
device /dev/drbd0;
disk /dev/loop0;
address 172.16.2.101:7788;
meta-disk internal;
}
on node2 {
device /dev/drbd0;
disk /dev/loop0;
address 172.16.2.102:7788;
meta-disk internal;
}
}
Error
When I try to use a drbdadm command I get the following error:
drbd.d/contentserver.res:4: Parse error: 'protocol | on | disk | net | syncer | startup | handlers | ignore-on | stacked-on-top-of' expected,
but got 'incon-degr-cmd' (TK 282)

Answer 1

I believe your resource file should read like this:
resource t0 {
protocol C;
pri-on-incon-degr "halt -f";
startup {
degr-wfc-timeout 120; # 2 minutes.
}
disk {
on-io-error detach;
}
net {
}
syncer {
rate 10M;
group 1;
al-extents 257;
}
on node1 {
device /dev/drbd0;
disk /dev/loop0;
address 172.16.2.101:7788;
meta-disk internal;
}
on node2 {
device /dev/drbd0;
disk /dev/loop0;
address 172.16.2.102:7788;
meta-disk internal;
}
}
