Change the filter line to search for DRBD partitions:

filter = [ "a|/dev/drbd.*|", "a|/dev/md1|", "r|.*|" ]

Edit /etc/sysconfig/cman to disable quorum (because there's only two nodes on the cluster):
```
sed -i.sed "s/.*CMAN_QUORUM_TIMEOUT=.*/CMAN_QUORUM_TIMEOUT=0/g" /etc/sysconfig/cman
```

Create /etc/cluster/cluster.conf to define the two-node Pacemaker configuration, with fencing.

Create a physical volume and a clustered volume group on the DRBD partition:
```
pvcreate /dev/drbd0
```

Create a physical volume and a clustered volume group on the DRBD partition. The name of the DRBD disk is /dev/drbd0; the name of the volume group is ADMIN.
```
pvcreate /dev/drbd0
```

vgcreate -c y ADMIN /dev/drbd0

For each logical volume in the volume group, create the volume and install a GFS2 filesystem; for example:
```
lvcreate -L 200G -n usr ADMIN # ... and so on
```

For each logical volume in the volume group, create the volume and install a GFS2 filesystem; for example, the following creates a logical volume usr within the volume group ADMIN:
```
lvcreate -L 200G -n usr ADMIN 
```

mkfs.gfs2 -p lock_dlm -j 2 -t Nevis_HA:usr /dev/ADMIN/usrNote that Nevis_HA is the cluster name defined in /etc/cluster/cluster.conf.

Make sure that cman, clvm2, and pacemaker daemons will start at boot; on both nodes, do:
```
/sbin/chkconfig cman on
```
