The Linux filesystem is a complex and the first thing that most new users shifting from Windows will find confusing is navigating the Linux filesystem. The second thing is that not too many people are familiar with how the filesystem works or know how to troubleshoot if any problems arise. The good thing is, there are many different types of file system tools and utilities available to make troubleshooting easier but again not too many people are familiar with them. We’ve put together top 20 of the most useful file systems tools and utilities that you’ll find useful in your Linux environment.
1. XFS - a high-performance journaling file system. It provides quick recovery after a crash, fast transactions, high scalability, and excellent bandwidth.
2. e2salvage - a utility which tries to recover a data from damaged ext2 filesystems. Unlike e2fsck, it does not look for the data at particular places and it don’t tend to believe the data it finds; thus it can handle much more damaged filesystem. Moreover, fsck connects the found i-nodes to lost+found directory. e2salvage instead tries to recover the directory structure.
