FYI, zfs is pretty fucking fragile, it breaks a lot, especially if you like to keep your kernel up to date. The kernel abi is just unstable and it takes months to catch up.
Which is part of why I don’t trust zfs on root.
Worst case you can sometimes recover with zfs-fuse.

Right, thanks for the heads up! On the desktops I have simply installed zfs as root via the Ubuntu 24.04 installer. Then, as the option was not available in the server variant I started to think maybe that is not something that should be done :p

It’s good, but be aware you want to stick to LTS kernels or at least don’t upgrade casually.
Arch is the worst for this, ubuntu and debian are better but still get hit.

Hit this recently on an arch build, switched to kernel-lts and it worked, but basically once every year or so the abi breaks and zfs is dead for 3-6 months on github.com/torvalds/linux@master. Just FYI.

Really good to know. Planned to keep using very mainstream LTS versions anyway, but this solidifies the decision. Maybe on a laptop I’ll install something more experimental but that’s then throwaway style.
