Arch Linux User Repository

OpenZFS currently supports Linux kernel versions 4.18 - 6.14, 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)

For some reasons, I cannot see the latest version (2.2.6-1) of this AUR package in the package manager:

pikaur -S zfs-dkms

Reading repository package databases...
Reading local package database...

 archzfs/zfs-dkms                      2.2.4-1              -> 2.2.4-1

@yurikoles If you build packages on your machine, then your machine is a build machine (to build the package per se). So I don't think this is a valid argument.

However since this package requires these tools post-installation too, they are arguably needed for zfs-dkms to function in its special 'runtime'. (I may be wrong.)

Anyway, I think it's better to move such kind of conversations to the mailing list, as it involves many official dkms packages too.

@fryfrog

This argument is valid for the AUR package build machine, but a target machine may differ, so the built package must contain all dependencies to be successfully installed and run.

@fryfrog thank you, it makes sense. Anyway I just realized that I hadn't installed aur yet, the issue is actually with zfs-dkms from archzfs repository.

@alepez: The base-devel package is assumed to be installed, a base requirement for using the AUR. That package contains at a glance autoconf and automake which both depend on perl. So if you've installed base-devel, you have perl. Sounds like you need to install the base-devel meta package or you'll run into more weird issues w/ aur packages.

Hi. I'm installing arch on zfs root. I've done this before in other systems. The build is failing with

configure: error:
        *** None of the expected "global page state" interfaces were detected.
        *** This may be because your kernel version is newer than what is
        *** supported, or you are using a patched custom kernel with
        *** incompatible modifications.

The actual error is not in make.log but in config.log

So perl is needed during dkms install, but on a fresh system it is not installed. After installing perl package, the problem is fixed.

Probably, adding perl as a dependency is a good idea.

@kstolp,

Thank you for updating zfs-dkms and zfs-utils. Can confirm both build, install and operate correctly against linux, -hardened and -zen, all of which are 6.10.X.

Cheers

ZFS 2.2.6, with support for the Linux kernel 6.10, has been released.

• When I've had problems building in the past it's usually a bad symlink under /var/lib/dkms/zfs - or possibly an old kernel under /lib/modules messing things up.

• I use the compiled zfs-dkms from EndeavourOS & arch-sign-modules from AUR to sign out of tree modules like zfs:

stuart@endeavour ~]$ ls /lib/modules/6.6.47-1-lts/updates/dkms/
lkrg.ko.zst        nvidia.ko.zst          nvidia-peermem.ko.zst  spl.ko.zst
nvidia-drm.ko.zst  nvidia-modeset.ko.zst  nvidia-uvm.ko.zst      zfs.ko.zst

[stuart@endeavour ~]$ modinfo /lib/modules/6.6.47-1-lts/updates/dkms/zfs.ko.zst 
filename:       /lib/modules/6.6.47-1-lts/updates/dkms/zfs.ko.zst
version:        2.2.5-1

• If you rm -rf /var/lib/dkms/zfs & reinstall zfs-dkms / zfs-utils & try again the modules will probably build. Alternatively try my method.

I installed zfs-dkms with aurutils. However, I get the following error.

# dkms install --no-depmod zfs/2.2.5 -k 6.6.47-1-lts

This is strange, because the contents of the directory actually seems to contain source code:

Any ideas about what the problem is? I'm totally lost in this situation. :-/ What's the contents of your /var/lib/dkms/zfs/2.2.5/source directory?
