When it comes to file systems, Linux® is the Swiss Army knife of operating systems. Linux supports a large number of file systems, from journaling to clustering to cryptographic. Linux is a wonderful platform for using standard and more exotic file systems and also for developing file systems.

You've probably heard of Journaling Flash File System (JFFS) and Yet Another Flash File System (YAFFS), but do you know what it means to have a file system that assumes an underlying flash device?

In recent history, journaling file systems were viewed as an oddity and thought of primarily in terms of research. But today, a journaling file system (ext3) is the default in Linux®. Discover the ideas behind journaling file systems, and learn how they provide better integrity in the face of a power failure or system crash. Learn about the various journaling file systems in use today, and peek into the next generation of journaling file systems.

Most probably you have heard many, many times the three words, virtual file system, but what exactly do they mean? In my recent article What does this /proc directory do?

Linux continues to innovate in the area of file systems. It supports the largest variety of file systems of any operating system. It also provides cutting-edge file system technology. Two new file systems that are making their way into Linux include the NiLFS(2) log-structured file system and the exofs object-based storage system.

One the coolest file systems in User Space has got to be GlusterFS. It has a very unique architecture that allows it to be configured for specific storage requirements and scenarios. It can be used as a high-performance parallel file system, or a cloud based file system, or even a simple NFS server. All of this in user-space.

This guide shows how to work with the btrfs file system on Linux. It covers creating and mounting btrfs file systems, resizing btrfs file systems online, adding and removing devices, changing RAID levels, creating subvolumes and snapshots, using compression and other things.

With the power bestowed upon us, we can create a Linux file system in a file. Humanly speaking, we can create a file containing specific file system and mount it as if it were a partition of a hard drive.
To do this, we must firs
