* Please welcome HAST - Highly Avalable Storage.Pawel Jakub Dawidek2010-02-181-0/+691
HAST allows to transparently store data on two physically separated machines connected over the TCP/IP network. HAST works in Primary-Secondary (Master-Backup, Master-Slave) configuration, which means that only one of the cluster nodes can be active at any given time. Only Primary node is able to handle I/O requests to HAST-managed devices. Currently HAST is limited to two cluster nodes in total. HAST operates on block level - it provides disk-like devices in /dev/hast/ directory for use by file systems and/or applications. Working on block level makes it transparent for file systems and applications. There in no difference between using HAST-provided device and raw disk, partition, etc. All of them are just regular GEOM providers in FreeBSD. For more information please consult hastd(8), hastctl(8) and hast.conf(5) manual pages, as well as http://wiki.FreeBSD.org/HAST.
