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.

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

We use btrfs for the / partition and xfs for any data partitions. Has served us well, the snapshot feature saves us some valuable time when an update goes awry.

I've been basically using btrfs on a lot of my disks because of the features it has.

Before I switched to a borg based system, my backups partition used btrfs for compression.

My main OS disk is btrfs so I can use timeshift snapshots, which are really worth checking out if you tinker with your system a lot.

I have two more btrfs partitions software raid0'd together for my steam library, nix store and other big but loosable things.

And my main home folder uses btrfs because I think the checksumming thing it does is more reliable for error detection, and cow is more fault tollerant on power failure?

... And I now fell like I'm one of those people with an over engineered storage solution. I just never get rid of old ssds or hard disks!

ext4, but the btrfs activity visible in the kernel changelog has slowed down recently after a long period of many bug fixes, so maybe I'll give it a try next time.

ZFS for my server’s root pool and main storage pool. Ext4 with snapraid for my media pool. Currently btrfs on my desktop and ext4 under vanillaos on my laptop (not sure if I could partition it manually to use btrfs but I’m considering that for snapshots)

[–] CalcProgrammer1@lemmy.ml 3 points 3 months ago

Pretty much all ext4 except for a few Windows installs on NTFS.

I tried exFAT for my USB stick but car sterio cannot read it.

Every photocopy machine I've come across that accept USB sticks do not support exFAT, so what I would do with my USB stick is to split it into two partitions, one FAT32 and the rest exFAT.

Depends on the device and the use case, mostly FAT32, exFAT, NTFS, EXT4

[–] cmnybo@discuss.tchncs.de 2 points 3 months ago

Most of my drives are EXT4, but I started using BTRFS a couple years ago and will be using it on all new installs from now on. I really like being able to make snapshots and compression reduces the install size quite a bit.

Xfs is solid Commenting b/c I'm disappointed no one else recommends

ext4 because I value my data and don't want to lose it. I used to mess about with ZFS for mass storage but it's a university course to learn how to use and have decent performance.

I used to use XFS, but ext4 caught up.

And I used to use XFS... on something other than Linux.

NTFS for the drive I had before jumping to Mint. Currently reporting several hundred gigabytes free, but refusing to make any new files, because... I don't know. I'll deal with it after an upcoming move.

The OS / home SSD is ext4, and so is the fat loud hard disk I recently purchased through an entire month of fighting Amazon over gift cards.

[–] Andromxda@lemmy.dbzer0.com 2 points 3 months ago

Btrfs on my Linux desktops and laptops, ZFS on my server, APFS on my Apple devices I guess

[–] Presi300@lemmy.world 2 points 3 months ago

EXT4 on PC, ZFS on my server and APFS on my mac
