Hello everyone. I’m going to build a new PC soon and I’m trying to maximize its reliability all I can. I’m using Debian Bookworm. I have a 1TB M2 SSD to boot on and a 4TB SATA SSD for storage. My goal is for the computer to last at least 10 years. It’s for personal use and work, playing games, making games, programming, drawing, 3d modelling etc.

I’ve been reading on filesystems and it seems like the best ones to preserve data if anything is lost or corrupted or went through a power outage are BTRFS and ZFS. However I’ve also read they have stability issues, unlike Ext4. It seems like a tradeoff then?

I’ve read that most of BTRFS’s stability issues come from trying to do RAID5/6 on it, which I’ll never do. Is everything else good enough? ZFS’s stability issues seem to mostly come from it having out-of-tree kernel modules, but how much of a problem is this in real-life use?

So far I’ve been thinking of using BTRFS for the boot drive and ZFS for the storage drive. But maybe it’s better to use BTRFS for both? I’ll of course keep backups but I would still like to ensure I’ll have to deal with stuff breaking as little as possible.

Thank you in advance for the advice.

    Hey, thanks for the help. Can you elaborate on what kind of issues BTRFS gave you? What caused them, too?

      Sure, I’ve used it both in Server and NAS scenarios. The NAS was where we had most issues. If the maintenance tasks for BTRFS weren’t scheduled to run (balance, defrag, scrub and another one i can’t recall), the disk could become “full” without actually being full. If I recall correctly it’s to do with how it handles metadata. There’s space, but you can’t save, delete or modify anything.

      On a VM, its easy enough to buy time by growing the disk and running the maintenance. On a NAS or physical machine however, you’re royally screwed without adding more disks (if its even an option). This “need to have space to make space” thing was pretty suboptimal.

      Granted now I know better and am aware of the maintenance tasks, I simply schedule them (with cron or similar). But I still have a bit of a sour taste from it, lol. Overall I don’t think it’s a bad FS as long as you look after it.

      It needs a bit of periodic maintenance, the btrfs-assistant and btrfsmaintenance packages will set it up and from then on it’s automatic.
