Highly Available STorage

Highly Available STorage (HAST) is a protocol and tool set for FreeBSD written by Pawel Jakub Dawidek, a core FreeBSD developer. HAST provides a block device to be synchronized between two servers for use as a filesystem. The two machines comprise a cluster, where each machine is a cluster node. HAST uses a Primary-Secondary (or Master-Slave) configuration, so only one cluster node is active at a time.
