Arch Linux User Repository

OpenZFS currently supports Linux kernel versions 4.18 - 6.15, as declared in the META file.

Options if your Linux kernel's version is not within that range:

1) Switch to another Linux kernel, such as linux-lts.

2) Prevent your kernel package from upgrading to an unsupported version until OpenZFS increases the maximum supported kernel version.

3) Modify this package to support your kernel by patching it on your local machine.

When requesting changes, please include detailed reasoning for the change.

If you receive this error when trying to build, it is because you have not imported the GPG keys used for verification.

==> ERROR: One or more PGP signatures could not be verified!

You have two options:

1) Import the two keys into your keyring. ArchWiki article. You can find the key IDs in the PKGBUILD file, in the validpgpkeys array. (recommended)

2) Alternatively, you can skip this verification by passing the --skippgpcheck argument to makepkg when building. (not recommended)

@fryfrog I'm actually using archzfs/zfs-dkms. Looks like I'm barking up the wrong tree... ;)

As a point of comparison, have you tried archzfs/zfs-dkms? While they're similar, they are slightly different.

Another option would be building the kernel yourself too, w/ the couple of patches to help ZFS.

^ This is what I'm currently applying to my self built kernel.

@eschwartz No matter what I do - reinstalling all related zfs packages including kernel and kernel headers etc. - I can't get the modules to build or install. Even worse, I can't get it to work with kernel 5.4.15 anymore either, the kernel that the system (booting from zfs) is currently running with. It looks like a bug upstream or some issue with some package hooks maybe, where stuff gets pulled from underneat dkms leaving it in a bad state?

As a workaround I replaced zfs-dkms with zfs-linux for now. I will try with the long-term kernel again after a reboot later today and maybe be able to provide more information.

@SRossi,

It builds fine for me. Did you try manually running sudo dkms install zfs/0.8.3 -k 5.4.18-1-lts?

I used to run stable kernels with zfs-dkms but since 5.5.x is not working with zfs, I would like to switch to the lts kernel tree.

(3/4) Install DKMS modules ==> dkms install zfs/0.8.3 -k 5.4.18-1-lts configure: error: *** Unable to build an empty module.

Is there any chance to get this done?

Build on 5.4.8 seems to be working flawlessly.

My installed version is: aur/zfs-dkms 0.8.3-1 (+90 2.98%) (Installed)

Any news on the 5.5.2 kernel release?

Build of zfs-dkms is failing again with kernel 5.5.1:

FATAL: modpost: GPL-incompatible module zfs.ko uses GPL-only symbol '__rcu_read_unlock'

Linux 5.5.1 breaks ZFS 0.8.3. If you're willing to patch your kernel there's a workaround here: https://github.com/zfsonlinux/zfs/issues/9745#issuecomment-573205923
