Installation
------------
If you want to use ZFS as your root filesystem, see the `Root on ZFS`_
links below instead.
Add archzfs repo
~~~~~~~~~~~~~~~~
ZFS packages are provided by the third-party
`archzfs repository <https://github.com/archzfs/archzfs>`__.
You can use it as follows.
Import archzfs GPG key::
curl -O https://archzfs.com/archzfs.gpg
pacman-key -a archzfs.gpg
pacman-key --lsign-key DDF7DB817396A49B2A2723F7403BD972F75D9D76
Add the archzfs repository::
tee -a /etc/pacman.conf <<- 'EOF'
[archzfs]
Server = https://archzfs.com/$repo/$arch
Server = https://mirror.sum7.eu/archlinux/archzfs/$repo/$arch
Server = https://mirror.biocrafting.net/archlinux/archzfs/$repo/$arch
Server = https://mirror.in.themindsmaze.com/archzfs/$repo/$arch
EOF
Update pacman database::
pacman -Sy
Prebuilt zfs package
~~~~~~~~~~~~~~~~~~~~
This only applies to vanilla Arch Linux kernels.
For other kernels, use `archzfs-dkms package`_.
You can also switch between DKMS and prebuilt
packages with instructions on this page.
Check kernel variant::
INST_LINVAR=$(sed 's|.*linux|linux|' /proc/cmdline | awk '{ print $1 }')
Install compatible package::
pacman -Sy archzfs-${INST_LINVAR}
If kernel dependency failed, you can either:
* Install `archzfs-dkms package`_, or
* Downgrade kernel
to a compatible version:
Downgrade to compatible kernel
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Check compatible kernel version::
INST_LINVER=$(pacman -Si zfs-${INST_LINVAR} \
| grep 'Depends On' \
| sed "s|.*${INST_LINVAR}=||" \
| awk '{ print $1 }')
Install compatible kernel::
pacman -U \
https://archive.archlinux.org/packages/l/${INST_LINVAR}/${INST_LINVAR}-${INST_LINVER}-x86_64.pkg.tar.zst
Install archzfs::
pacman -Sy archzfs-${INST_LINVAR}
Ignore kernel update when dependency fails
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Sometimes archzfs prebuilt package might lag behind
kernel updates::
pacman -Syu
# error: failed to prepare transaction (could not satisfy dependencies)
# :: installing linux-lts (5.4.93-2) breaks dependency 'linux-lts=5.4.92-1' required by zfs-linux-lts
Temporarily ignore kernel update to upgrade other packages::
pacman -Syu --ignore=linux-lts
archzfs-dkms package
~~~~~~~~~~~~~~~~~~~~
This package will dynamically build ZFS modules for
supported kernels. Both Arch Linux and derivatives
are supported.
Check OpenZFS compatibility
^^^^^^^^^^^^^^^^^^^^^^^^^^^
Check kernel version::
uname -r
# 5.4.92-1-lts
Check newer archzfs-dkms package version::
DKMS_VER=$(pacman -Si zfs-dkms \
| grep 'Version' \
| awk '{ print $3 }' \
| sed 's|-.*||')
Visit OpenZFS release page ::
curl https://github.com/openzfs/zfs/releases/zfs-${DKMS_VER} \
| grep Linux
# Linux: compatible with 3.10 - 5.10 kernels
If it's not supported, see `Install alternative kernel`_.
Otherwise, continue to next step.
Normal installation
^^^^^^^^^^^^^^^^^^^
Check kernel variant::
INST_LINVAR=$(sed 's|.*linux|linux|' /proc/cmdline | awk '{ print $1 }')
Check kernel version::
INST_LINVER=$(pacman -Qi ${INST_LINVAR} | grep Version | awk '{ print $3 }')
Install kernel headers::
pacman -U https://archive.archlinux.org/packages/l/${INST_LINVAR}-headers/${INST_LINVAR}-headers-${INST_LINVER}-x86_64.pkg.tar.zst
# for artix
pacman -U https://archive.artixlinux.org/packages/l/${INST_LINVAR}-headers/${INST_LINVAR}-headers-${INST_LINVER}-x86_64.pkg.tar.zst
Install archzfs-dkms::
pacman -Sy archzfs-dkms
Hold kernel package from updates::
sed -i 's/#.*IgnorePkg/IgnorePkg/' /etc/pacman.conf
sed -i "/^IgnorePkg/ s/$/ ${INST_LINVAR} ${INST_LINVAR}-headers/" /etc/pacman.conf
Kernel must be manually updated, see `Kernel update`_.
Install alternative kernel
^^^^^^^^^^^^^^^^^^^^^^^^^^^
If the kernel is not yet supported, install a supported kernel:
Choose kernel variant. Available variants are:
* linux
* linux-lts
For Artix, replace ``archlinux.org`` with ``artixlinux.org``.
::
INST_LINVAR=linux
Check build date::
DKMS_DATE=$(pacman -Syi zfs-dkms \
| grep 'Build Date' \
| sed 's/.*: //' \
| LC_ALL=C xargs -i{} date -d {} +%Y/%m/%d)
Check kernel version::
curl https://archive.archlinux.org/repos/${DKMS_DATE}/core/os/x86_64/ \
| grep \"${INST_LINVAR}-'[0-9]' \
| grep -v sig
# <a href="linux-5.10.3.arch1-1-x86_64.pkg.tar.zst">
Set kernel version in a variable::
# <a href="linux-5.10.3.arch1-1-x86_64.pkg.tar.zst">
INST_LINVER=5.10.3.arch1-1
Install kernel and headers::
pacman -U \
https://archive.archlinux.org/packages/l/${INST_LINVAR}/${INST_LINVAR}-${INST_LINVER}-x86_64.pkg.tar.zst \
https://archive.archlinux.org/packages/l/${INST_LINVAR}-headers/${INST_LINVAR}-headers-${INST_LINVER}-x86_64.pkg.tar.zst
Install archzfs-dkms::
pacman -Sy archzfs-dkms
Hold kernel package from updates::
sed -i 's/#IgnorePkg/IgnorePkg/' /etc/pacman.conf
sed -i "/^IgnorePkg/ s/$/ ${INST_LINVAR} ${INST_LINVAR}-headers/" /etc/pacman.conf
Kernel must be manually updated, see `Kernel update`_.
Kernel update
^^^^^^^^^^^^^
This applies to archzfs-dkms package.
Check kernel variant::
INST_LINVAR=$(sed 's|.*linux|linux|' /proc/cmdline | awk '{ print $1 }')
Check newer kernel version::
pacman -Syi $INST_LINVAR \
| grep 'Version' \
| awk '{ print $3 }'
# 5.10.1.1-1
Check newer archzfs-dkms package version::
DKMS_VER=$(pacman -Si zfs-dkms \
| grep 'Version' \
| awk '{ print $3 }' \
| sed 's|-.*||')
Visit OpenZFS release page ::
curl https://github.com/openzfs/zfs/releases/zfs-${DKMS_VER} \
| grep Linux
# Linux: compatible with 3.10 - 5.10 kernels
If compatible, update kernel with::
pacman -S $INST_LINVAR $INST_LINVAR-headers archzfs-dkms
Do not update if the kernel is not compatible
with OpenZFS.
glibc version mismatch
^^^^^^^^^^^^^^^^^^^^^^
As of Feb 6th, 2021, latest glibc release is ``2.33``.
glibc in Arch Linux repo is ``2.32``.
When updating ``linux-lts (5.4.94-1 -> 5.4.95-1)``,
``linux-lts-headers`` will depend on the unavailable glibc ``2.33``

/usr/lib/modules/5.4.95-1-lts/build/scripts/basic/fixdep is owned by linux-lts-headers 5.4.95-1
To solve the problem, rollback kernel update
and postpone kernel updates
until glibc ``2.33`` becomes available.
