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

So, genuine question: why btrfs instead of zfs? Sounds like your use case would fit the latter.

BTRFS is zero effort on root, because it is included in kernel. ZFS on root is extra effort at least on Arch, due to licensing restrictions.

Additionally, at least for my use-case btrfs benefits me since it is less picky about drive sizes being the same and duplicating everything correctly - letting you essentially just throw additional storage at it as you acquire it.

Does ZFS handle data duplication on unequal sized volumes or heterogeneous pools? I don’t believe so, and BTRFS was a first class installer option.
