Let's agree to disagree here. Valve' Steamdeck has a dual BTRFS/Ext4 setup because BTRFS doesn't handle their use-case just fine. ZFS, oddly enough, would have.

Propensity to eat the whole filesystem when there's a disk media error in the right spot, spiral-of-doom freespace pathologies when more than half the disk is full, and then the forever-broken raid implementation that the devs outright warn against using. The list goes on.
BTRFS has been perpetually unfinished for over 10 years now and I doubt it will ever get across the finish line. Honestly, nobody should be using it in it's truthfully-developmental state.

Let's not forget RHEL backtracked hard on BTRFS and according to the lead they're not planning to use it for any enterprise products.- Ubuntu: ext4 with an option for ZFS (which as of 22.04 isn't labeled as experimental anymore)
- Fedora: Btrfs (with a big interest in it after RH had already gone the Stratis route)
- OpenSUSE: Btrfs
Red Hat is the 800 lb gorilla in the enterprise space, and there is some obvious value (and monetary) add in going their own way with Stratis. If they can offer enterprise storage features (space efficient RAID levels / pooling / tiering / send|receive / etc.) with no out of tree modules with a good API that is slickly integrated into Cockpit, there is some good upside for them. As desktop users we'd probably be better off if they invested in getting Btrfs to that point, but from the outside looking in it's hard to say if they didn't because they didn't believe it was possible, or they saw an opportunity for differentiation and dollars.

This article has some rather terrible assumptions:
1) that there haven't been any updates for Zsys because it's been abandoned (they literally just updated it)
2) that ubuntu would switch to ZFS overnight and therefore it must have "stagnated"
3) that ubuntu haven't put out a blog post in a while, so they must be loosing interest
3) that the licencing remains "murky." (ubuntu have published their legal opinions at length now, with numerous other analyses to back them up from different angles. it's been shipping for 6+ years now, find another dead horse guys)
It clear that ubuntu are instead taking the gradual approach, adding more ZFS support with each new release. First an official repo package, then an experimental installer option, then a supported ZFS-on-root configuration, and so on. And why should they rush? This is a very long-term project and one sure to cause breakage here and there, and most people are still warm and cozy with ext4.

Note that you didn't read their comment long enough to know they explicitly stated their problem is unrelated to Zsys.

Reports of data loss with ZFS are comparatively very hard to find. In all the years fishworks made ZFS storage appliances nobody list data, ever. [1]
On the contrary, EVERYONE has heard several stories of BTRFs barfing. eg:

Many devices use this combo because they don't need any of the more advanced features in COW based filesystems in select situations and instead just want the raw better performance that COW based fs will not give you.You can totally switch if you want to https://github.com/Trevo525/btrfdeck
I can tell you from personal experience that it can be god awful trying to use various Elder Scrolls games mods on Linux due to case sensitivity issues.
And, holy shit, I don't necessarily agree with how homie in that link is using BTRFS zstd:15 on a partition for interactive data.Last edited by skeevy420; 12 April 2022, 04:36 PM.
