For example:

resource r0 {
  on alice {
    device    /dev/drbd1;
    disk      /dev/mapper/vg_foo-bar;
    address   10.1.1.31:7789;
    meta-disk internal;
  }
  on bob {
    device    /dev/drbd1;
    disk      /dev/mapper/vg_foo-bar;
    address   10.1.1.32:7789;
    meta-disk internal;
  }
}

Where /dev/mapper/vg_foo-bar is an LVM Logical Volume.

This is in contrast to using /drv/drbd1 as the basis for an LVM Physical
Volume (ie: doing "pvcreate /dev/drbd1").

Mark.
