    + ---help---
    + DRBD is a block device which is designed to build high availability
    + clusters. This is done by mirroring a whole block device via (a
    + dedicated) network. You could see it as a network RAID 1.
    +
    + Each minor device has a state, which can be 'primary' or 'secondary'.
    + On the node with the primary device the application is supposed to
    + run and to access the device (/dev/drbdX). Every write is sent to the
    + local 'lower level block device' and via network to the node with the
    + device in 'secondary' state.
    + The secondary device simply writes the data to its lower level block
    + device. Currently no read-balancing via the network is done.
    +
    + DRBD can also be used with "shared-disk semantics" (primary-primary),
    + even though it is a "shared-nothing cluster". You'd need to use a
    + cluster file system on top of that for cache coherency.
    +
    + DRBD management is done through user-space tools.
    + For automatic failover you need a cluster manager (e.g. heartbeat).
    + See also: http://www.drbd.org/, http://www.linux-ha.org
    +
    + If unsure, say N.
