Yet another ... which Linux file systems ?

(1/21) > >>

BravoV:
Planning to replace the aging swmbo desktop, and she practically used it just for casual documents work like word processing, spreadsheet and browsing. And also she does a lot of photos & videos backup from her phone into the desktop storage. And casually plays old windows games.

And no, no cloud storage discussion please.

Me my self and her are Linux noob, but decades of Windows experiences.

Planned configuration :

- Quad core ryzen
- Memory 16 GB (ECC or non ECC, subject to final decision) ... done deal, ECC it is.
- Boot drive NVME 1TB
- Storage 3 x 8TB (Raid 5 or RAID-Z1)

OS , will try forcing luring her into Linux and probably with Windows VM.  :P

Regarding the RAID, I'm fully aware as this is just to reduce down times, we have an air gapped external HD 16TB which we do routine monthly backup.

Also regarding desktop RAID, I'm fully familiar since early days of fake raid using Intel chip-set up to dedicated  LSI Megaraid, its just I'm getting tired having to rely on the controller as single point of failure, beside its only for casual desktop usage, not high end enterprise grade server, CMIIW.

Questions :

This regarding the file system :

Option 1
Boot drive : EXT4
3 x 8TB : On MDADM

Option 2
Boot drive : EXT4
3 x 8TB : ZFS RAID-Z1

Option 3
Boot drive : ZFS
3 x 8TB : ZFS RAID-Z1  ... option 1 is decided.

Linux distro decision ... latest Ubuntu LTS ?  :-//

Regarding physical drives nvme + 3 HD decision, its already fixed and purchased.

Or .. any other suggestions , critics maybe on my plan ?

Unless you are skilled and know it, go with the filesystem your preferred distro uses, you'll have less hassles that way. Performance isn't going be an issue for your workload.

I recently set up a Linux system to be my daily use replacement for a Windows 7 machine. I went with whatever Debian uses by default and never gave it a second thought.

I would consider using those 3 8TB drives as basis for a FreeNAS set up, but that would mean getting another computer suitable for that purpose.

RoGeorge:
ZFS can do many things that ext4 can't, and by design is more reliable, definitely ZFS.  I will go for Option 3, or maybe an Option 4:  Ubuntu 20.04 LTS + 1TB (ZFS OS) + 8TB ZFS + 2x8TB ZFS RAID1 powered only during backups.

For the enumerated applications, there should be no need to use Windows VMs.

0db:
Ext4 in my experiences was pure crap.
