In this video, Kevin Dankwardt discusses the features of a variety of Linux file systems. Special features of ext4, XFS, and Vtrfs are examined. Kevin discusses how features such as performance and journaling can be used to distinguish file systems.
- [Instructor] File system types.…Linux has lots of kinds of file systems.…Some of those are pseudo kind of file systems…like proc and sysfs, but there's many kinds of file systems…for disk file systems.…The recent Linux kernel, for example,…has 95 different calls to register_filesystem(),…which is the function that code uses…to register the different parts of the API…to support being a file system.…
So, XFS would register a file system,…and exd4 would, and exd2 would, and so forth.…So there's lots of kinds of file systems in the kernel.…For disk-based file systems,…there's a lot of ways that file systems…can differ from each other.…For example, if a file system supports journaling.…A journal is writing what you're going to do.…I'm going to change this sector.…Then, after you're done changing that sector,…then you can say I wrote it.…
The good thing about a journal is…you say what you're going to do,…so you have a list of what you're working on,…and if you lose power, when we come back up,…we can look at the journal to see what we're working on…
