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.

What file systems are you using on your devices and why? (en.wikipedia.org)

I want to learn more about file systems from the practical point of view so I know what to expect, how to approach them and what experience positive or negative you had / have.

I found this wikipedia's comparison but I want your hands-on views.

For now my mental list is

NTFS - for some reason TVs on USB love these and also Windows + Linux can read and write this
Ext4 - solid fs with journaling but Linux specific
Btrfs - some modern fs with snapshot capability, Linux specific
xfs - servers really like these as they are performant, Linux specific
FAT32 - limited but recognizable everywhere
exFAT - like FAT32 but less recognizable and less limited

Never doubted it. Do you use journaling feature on it?

[–] [email protected] 5 points 3 months ago

I like ext4 because it's easy. If anything breaks, ANY live USB can fix it. I use fat32 for my removeable drives, because anything can read it. I don't use journalling for anything manually, but I imagine it's useful when my disk crashes because I let my laptop die

Wasn't that the entire purpose of ext4 vs ext3? As the default, I also keep journaling on for ext4 partitions. Even /boot.

ext3 had journaling, but not ext2. Also ext3 doesn't really exist anymore as it was merged into the ext4 driver which can read the old format.
