Cannot install ZFS

General system Newbie

So, this is the mission:
I have a ZFS-formatted disk (one half of a ZFS mirror) on an NVME “disk” that I want to read data of. The “disk” will be attached via USB - Adapter from icybox.
I thought to myself “easy task, let’s got and install zfs and be happy”. Does not work:

yay -S zfs

What is the issue here?

zfs-dkms hasn’t been patched for kernel 6.11 yet. The easiest solution is to use the LTS kernel. In general, when using zfs you are better off using the LTS kernel unless you are using the archzfs repo.

Alternatively, you could use zfs-dkms-git instead.

Or alternatively, compile your own kernel with zfs baked in. Or find a provided kernel that does (I have no idea if any do).
I’m using LTS and zfs-dkms myself as Dalto suggested on a headless server. Trying to run current kernel with ZFS is a moderate nightmare. Unless you really need zfs (which I pretty much do/did), I’d recommend pulling the data and reformatting to another FS.

The archzfs repo makes it pretty easy if you ever need to do so for any reason.

For the OP’s scenario though, I would just boot into the LTS kernel though since they already have it installed.

But the archzfs is providing zfs for newer kernels like 6.11 without official release for that kernel version. This is not what I would do.

It is doing the opposite of that. Not allowing the kernel to update until zfs is ready. It is currently on 6.9.7

To be clear, I think running LTS is the best option. But if you are in a situation where you cannot run LTS, then I think archzfs is an option.

EDIT: Now that I post that, it seems bad. It should really be on 6.10.x and zfs 2.2.6. :frowning:

Just booting into LTS did the trick - I am with stupid, ty all guys, much love and respect!

I havent checked out archzfs for a while. You are right. It seems to be fine now.

For kernel 6.9 they provided zfs 2.2.4 without official support. I created the ticket at that time:

In the meantime, starting with zfs 2.2.5, the zfs developer implemented a patch that prevent compilation with unsupported kernel version.

Now archzfs is basically forced to stick to the officially supported kernel versions

But 2.2.6 has been released at this point with support for 6.10. It seems like that should be there.
