Arch Linux User Repository

@torben thank you for the suggestion! I think linux-lts and zfs-linux-lts is the best option here.

@CoolGenie zfs-linux is in sync with arch core right now. The error you are getting happens because you have an old version of zfs-linux installed. So you need to remove the old one first before updating.

If this is too much effort, you can also use the archzfs repository (https://github.com/archzfs/archzfs/wiki) or zfs-dkms.

PS: There is a variable called _kernelver in the PKGBUILD, which you can adjust and rebuild if the aur version is out of date.

Right! In your account settings "Notify of package updates" needs to be checked too. It was unchecked for me. Now I'll probably get way more emails than I want!

qdmp1ce: Just klick on "Enable notifications" in the "Package Actions" box on the top right. IIRC you have to create an account to do so.

@torben, how do you subscribe to zfs-linux updates?

@CoolGenie: The problem here is, that current Arch is a moving target, that's difficult to follow at times. For me personally I've tried a few options you might try as well:

a) Switch to the ZFS Kernel LFS branch (zfs-linux-lts), this is what I use. You'll less frequent kernel updates, I haven't had much of a problem with the LTS branch and ZFS since I switched to it. Works well and using the LTS kernel might actually be preferrably on servers. On cutting edge desktops/notebooks this might not be an option though; but since ZFS is more of a server technology, this shouldn't be that much of a point. I'd recommend this approach.

b) Subscribe to zfs-linux package updates and do your pacman update right after the ZFS upgrade is out. This worked for me most of the time I was quick enough, I just didn't see any advantage over the LTS branch so I stopped doing so.

c) Use the DKMS version, which custom-builds the modules on your box, I've tried this once but didn't get it to run, however, as far as I understand this should work in principle (probably I missed something when I tried it).

I understand the pains of open source development and much appreciate the work everyone is doing at Arch, however I've been unable to upgrade for over a month now with the error:

error: failed to prepare transaction (could not satisfy dependencies) :: installing linux (5.4.12.arch1-1) breaks dependency 'linux=5.4.1.arch1-1' required by zfs-linux

I think it's important to follow the upstream kernel because this blocks any security updates from the upstream Arch. And, when having migrated important data to ZFS, I can't just uninstall zfs-linux :)

@CoolGenie you need to wait until the zfs-linux package gets updated with the current kernel as dependency.

Anyone know why I'm getting: installing linux (5.4.2.arch1-1) breaks dependency 'linux=5.4.1.arch1-1' required by zfs-linux

Root on encrypted ZFS can be decrypted during boot when adding "zfs load-key -a" around line 54 in the mkinitcpio hook "/usr/lib/initcpio/hooks/zfs". @minextu maybe consider as permanent patch?
