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

How well a file system recovers from crashes or corruption.

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

  • Ext4 main computer
  • NTFS for hard drives and stuff that need to be shared with other people using Windows
  • BTRFS for the NAS

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

[–] tired_n_bored@lemmy.world 2 points 11 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 11 months ago (1 children)

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

[–] tired_n_bored@lemmy.world 2 points 11 months ago (2 children)

You have to run a so-called scrub command that checks for errors and tries to repair them. You can automate to run it every month or so

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.

My regular computer is ext4.

I assume my raspberry pi is ext4, but I've never checked what DietPi runs as default. It works fine.

My 720xd is ext4 on the OS drives, but the storage drives are ZFS with dual parity.

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.
