Ext3fs
Third Extended Filesystem. The Ext3 filesystem is a journaling extension to the standard Ext2 filesystem on Linux. Journaling results in massively reduced time spent recovering a filesystem after a crash, and is therefore in high demand in environments where high availability is important, not only to improve recovery times on single machines but also to allow a crashed machine's filesystem to be recovered on another machine when we have a cluster of nodes with a shared disk.

Ext2fs
Second Extended Filesystem. Ext2fs provides a powerful filesystem, which implements Unix file semantics and offers advanced features. it is a very robust filesystem designed to reduce the risk of data loss in intensive use. It has excellent performance and includes provision for extensions to allow users to benefit from new features without reformatting.

JFS for Linux
IBM's journaled file system technology, currently used in IBM enterprise servers, is designed for high-throughput server environments, key to running intranet and other high-performance e-business file servers. IBM is contributing this technology to the Linux open source community with the hope that some or all of it will be useful in bringing the best of journaling capabilities to the Linux operating system.

XFS
XFS is a high-performance journaling filesystem. It combines advanced journaling technology with full 64-bit addressing and scalable structures and algorithms. This combination delivers the most scalable high-performance filesystem ever conceived. Great FS to use for /var and /tmp
