The FreeBSD Foundation has announced that is funding a new funded project: HAST
“Pawel Jakub Dawidek has been awarded a grant to implement storage replication software that will enable users to use the FreeBSD operating system for highly available configurations where data has to be shared across the cluster nodes. The project is partly being funded by OMCnet Internet Service and TransIP BV.
The software will allow for synchronous block-level replication of any storage media (GEOM providers, using FreeBSD nomenclature) over the TCP/IP network and for fast failure recovery. HAST will provide storage
using GEOM infrastructure, which means it will be file system and application independent and could be combined with any existing GEOM class. In case of a master node failure, the cluster will be able to
switch to the slave node, check and mount UFS file system or import ZFS pool and continue to work without missing a single bit of data.
High-availability is the number one requirement for any serious use of any operating system,
said Pawel Jakub Dawidek, FreeBSD Developer.
Highly available storage is one of the key components in such environments. I strongly believe there are many FreeBSD users that have been waiting a long time for this functionality. I’ll do my best to deliver software that matches FreeBSD quality and that will satisfy the needs of our users.
Pawel has been an active FreeBSD committer since 2003. During this period, he has touched almost every part of the kernel. But, his main interest in FreeBSD is storage and security related topics. Pawel is the author of various GEOM classes (eli, mirror, gate, label, journal, hsec, etc.), geom(8) utility, various opencrypto improvements as well as port of the ZFS file system from OpenSolaris to FreeBSD.
The project will complete by February 2010.”
