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

ext4 on everything except external drives where I put NTFS.

Btrfs because it sounded cool when I first read about it and worked fine so far :3

[–] Psyhackological@lemmy.ml 1 points 3 months ago (1 children)

Yeah it sounds "better" FS. Do you use snapshots?

[–] CatLikeLemming@lemmy.blahaj.zone 2 points 3 months ago

Yep, got Timeshift hooked up to make a snapshot each time I update my system and I can boot into them via GRUB. Haven't needed that so far, thankfully, but it's there just in case.

  • Ext4 main computer
  • NTFS for hard drives and stuff that need to be shared with other people using Windows
  • BTRFS for the NAS
[–] Psyhackological@lemmy.ml 1 points 3 months ago (1 children)

Interesting choice for NAS, why not the others that seem like better alternatives?

[–] tired_n_bored@lemmy.world 2 points 3 months ago (1 children)

Well, as far as I know, BTRFS and ZFS are the recommended file systems for NAS's. They have self-healing capabilities so I can be slightly more sure that my data does not get corrupted over time.

[–] Psyhackological@lemmy.ml 2 points 3 months ago (3 children)

Is self-healing process automated or you need to somehow enable it so it happens from time to time?

Btrfs, but if I'd start from scratch today I'd go for bcachefs.

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.

Random thoughts, no particular order

I think btrfs was the default the last time I installed Bazzite, but I don't really know anything about it so I switched it to ext4. I understand the snapshot ability is nice with rolling release distros, though.

It'd been ages since I'd used FAT32 for anything until I made a Debian live USB when I was setting up my pi-hole on an old Core2Duo recently. It would only boot on FAT32 for reasons I probably once knew. 😆

NTFS was an improvement over the FATs what with the journaling, security, file streams, etc. I use it wherever I still use Windows (work).

Most of my general purpose USB flash drives use exFAT. I like not having to worry about eject/unmount.

I've got Btrfs on my desktop for the OS drive cuz that was what Fedora recommended when I was installing it. It took a bit of effort to get snapshots working properly, but other than that, I've had no issues with it at all over the past year. I've got an exFAT drive and an NTFS drive in there that are kind of leftovers from using Windows. I've been thinking about reformatting the exFAT drive to ext4 or something, since all it really does is store games, and having the ability to symlink to it would be nice.

I've got a TrueNAS machine as well and that uses ZFS for pretty much everything.

I wish I'd actually chosen a file system instead of just letting window's at the time default to NTFS for external drives.

Moving from Windows to Debian; NTFS has been nothing but a headache. I've actually had to setup a windows machine to serve that drive pool via SAMBA as Linux just won't play nicely with it.
