What file systems are you using on your devices and why?

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

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.

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.

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.

Ext4 and ZFS.

  • Ext4 for system disks because it’s default in OS installers and it works well. I typically use it on top of LVMRAID (LVM-managed mdraid) for redundancy and expansion flexibility.
  • ZFS for storage because it’s got data integrity verification, trivial setup, flexible redundancy topologies, free snapshots, blazing fast replication, easy expansion, incredible flexibility in separating data and performance tuning within the same filesystem. I’d be looking into setting up ZFS on root for my next machine. Among other things that would enable trivial and blazing fast backup of the system while it’s running - as simple as syncoid -r rpool backup-server:machine4-rpool.

Ext4 is the only good FS so that’s what I use.

henfredemars ,

Many different file systems are successfully used in production on a large scale that aren’t EXT4.

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.

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.

same

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

ZFS, got 5 system with different zpools

On root?

ryannathans ,

Mine is

scottmeme ,

I do have 1 system with ZFS mirror boot drives

avidamoeba ,
@avidamoeba@lemmy.ca avatar

Did you use an installer to do it or manual setup?

scottmeme ,

Proxmox install on the zfs mirror boot plus some other pools, everything else is currently truenas single boot drive with pools

I do have other proxmox stuff running zfs*

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