About FreeBSD HAST Project

For a long time, I’m a hardcore of FreeBSD, prefer FreeBSD to Linux. But as far as virtualization concerned, FreeBSD is not well supported as a host OS by any of the available virtualization solutions. With the official (not experimental) support of ZFS in FreeBSD 8.0, FreeBSD is now a decent choice of storage system.

Today I wanna introduce a new project – FreeBSD HAST Project, aka FreeBSD High Availability Storage Project. The main purpose of this great project is enable users to use the FreeBSD operating system for highly available configurations where data has to be shared across the cluster nodes.

HAST enables users to use the FreeBSD operating system for highly available configurations where data has to be shared across the cluster nodes. 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.

The project developer is Pawel Jakub Dawidek, and the project will completed by February 2010.

Hi everyone,

Since FreeBSD 7.0 was recently released, I figured it’s a good time to put a VMware image together and have a look. Probably one of the most interesting new enhancements is the addition of the ZFS filesystem. I can’t wait to try that out, and it should make managing disk space a lot easier in the context of the SourceHosting.net service.

You can find the zipped image on the SourceHosting.net BitTorrent tracker. Some notes about the image:

The VM has been configured with 768Mb of memory. You can reduce it to 512Mb, but the ZFS documentation says “Me want more memory!“
The root password is “password”
ZFS is enabled by default
The /usr/ports filesystem is located in a ZFS pool
The Ethernet interface is bridged to the host and uses DHCP

I tested this VM in VMware Server and VMware Player, and it seems to work fine. If you have any questions or problems, feel free to post comments here.

Keep in touch,
Greg

FreeBSD 7.0 已经可以支持 ZFS 文件系统了，不过还处于测试阶段，不推荐用于生产环境。
