DRBD

LinBit's system for mirroring filesystems across the Network, typically a dedicated LAN, written by Philipp Reisner and LarsEllenberg. This is the general replication technology which is most commonly used by members of the Linux-HA community. By the way, DRBD is a registered trademark of LinBit.

The DRBD User's Guide is excellent documentation and reference, you are strongly encouraged to thoroughly read it. Learn how to set it up manually and how things work. Use DRBD manually to get a feeling for what it does. Then you may start thinking about using it as a cluster resource.

A background paper by Lars on DRBD 8.0.x is recommended.
