Provides the same effect as DRBD? ... not really ... as DRBD provides a
second machine in hot standby mode with a totally synced partition that
is ready to take over on a failure of the first machine.  If the first
computer blows up (power supply, hard drive crash, etc.), the second one
starts up and takes over with no down time (except the time it takes to
mount the partition and start the services on the new machine).
