[Pacemaker] Fwd: drbd outdate peer

Furthermore, if I insert
outdate-peer "echo $DRBD_RESOURCE > /tempfile";
and unplug the replication link ethernet I see in /tempfile the word r1 that
is the name of the resource.
Instead if I insert
outdate-peer "echo $DRBD_PEER > /tempfile";
and unplug the replication link ethernet the file /tempfile is blank.
So the $DRBD_PEER variable is blank, why????
Anyone can help me??
Thanks.

Another information:
If I insert the node name and resource in the drbd-peer-outdater it works
well!!
(I insert outdate-peer "/usr/lib64/heartbeat/drbd-peer-outdater -p
centos-xen2 -r r1"; in the drbd.conf of the centos-xen1 node where the
resource is master).
Seems that the drbd-outdater doesn't find the name of the peer.
Why?

This is ha.cf file:
debugfile /var/log/ha-debug
logfile /var/log/ha-log
logfacility none
bcast eth0 eth1
auto_failback on
node centos-xen1 centos-xen2
respawn root /usr/lib64/heartbeat/mgmtd -v
respawn root /usr/lib64/heartbeat/dopd
apiauth mgmtd uid=root
apiauth dopd uid=root
crm yes
and this the drbd.conf file:
global { usage-count no; }
common { syncer { rate 10M; verify-alg md5; } }
resource r1 {
protocol C;
startup {wfc-timeout 60;
degr-wfc-timeout 50;
}
disk { on-io-error detach;
fencing resource-only;
}
handlers {
outdate-peer "/usr/lib64/heartbeat/drbd-peer-outdater";
}
on centos-xen1 {
device /dev/drbd1;
disk /dev/sda3;
address 172.16.0.1:7789;
meta-disk internal;
}
on centos-xen2 {
device /dev/drbd1;
disk /dev/hda3;
address 172.16.0.2:7789;
meta-disk internal;
}
}
And then this is what I say in the messages
