It mirrors data over the network. The backing device on each node can be either low level device like /dev/sda1 or a logical volume. In the versions I'm familiar with (0.8), only one of the nodes can mount the drbd device as read write. But, if you have multiple drbd resources (e.g. /home/xxx/yyy and /opt/zzz), you could mount one directory rw on one node and the other directory rw on the other node. -- Jiann-Ming Su "I have to decide between two equally frightening options.
