"XFS"和"Reiserfs",还有ext3都是Linux支持的日志文件系统!
XFS:是SGI公司开发(开源)的日志文件系统,原用于SGI的Unix上的FS。 XFS: A high-performance journaling filesystem
XFS combines advanced journaling technology with full 64-bit addressing and scalable structures and algorithms. This combination delivers the most scalable and high-performance filesystem in the world.详见SGI http://oss.sgi.com/projects/xfs/
Reiserfs是另一种日志文件系统,它的优异性能体现在对小文件的处理上,速度非常快! http://www.namesys.com/[/url]
XFS is a filesystem with metadata journaling which comes with a robust feature-set and is optimized for scalability. We only recommend using this filesystem on Linux systems with high-end SCSI and/or fibre channel storage and an uninterruptible power supply. Because XFS aggressively caches in-transit data in RAM, improperly designed programs (those that don't take proper precautions when writing files to disk and there are quite a few of them) can lose a good deal of data if the system goes down unexpectedly.
