From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Just a simple question : Which file system do you recommend for Linux? Ext4...?

EDIT : Thanks to everyone who commented, I think I will try btrfs on my root partition and keep ext4 for my home directory 😃

Good that you mentioned that. Reminded me that I have an Arch Linux install here where I forgot that I did choose BTRFS during installation. Within maybe a month I noticed FS errors. Looked scary. Nervously searching for documentation was even more scary :

https://wiki.archlinux.org/title/btrfs#btrfs_check -> This article or section is out of date. (Discuss in Talk:Btrfs) Warning: Since Btrfs is under heavy development, especially the btrfs check command, it is highly recommended to create a backup and consult btrfs-check(8) before executing btrfs check with the --repair switch.

What is this? My beloved Arch Wiki is not 100% perfect!

Then found this :

WARNING: Using '--repair' can further damage a filesystem instead of helping if it can't fix your particular issue.

Warning

Do not use --repair unless you are advised to do so by a developer or an experienced user, and then only after having accepted that no fsck successfully repair all types of filesystem corruption. E.g. some other software or hardware bugs can fatally damage a volume.

I figure this explains the popularity of BTRFS snapshot configurations. Luckily I had some backups :)

Filesystem snapshots won't help, if the filesystem itself corrupts. But I've been using BTRFS for 6 years now and haven't had a file system corruption, so mileage may obviously vary.
