Installation
|
|
------------
|
|
|
|
If you want to use ZFS as your root filesystem, see the `Root on ZFS`_
|
|
links below instead.
|
|
|
|
archzfs repo
|
|
~~~~~~~~~~~~
|
|
|
|
ZFS packages are provided by the third-party
|
|
`archzfs repository <https://github.com/archzfs/archzfs>`__.
|
|
You can use it as follows.
|
|
|
|
#. Import keys of archzfs repository::
|
|
|
|
curl -L https://archzfs.com/archzfs.gpg | pacman-key -a -
|
|
curl -L https://git.io/JtQpl | xargs -i{} pacman-key --lsign-key {}
|
|
|
|
#. Add archzfs repository::
|
|
|
|
tee -a /etc/pacman.conf <<- 'EOF'
|
|
|
|
#[archzfs-testing]
|
|
#Include = /etc/pacman.d/mirrorlist-archzfs
|
|
|
|
[archzfs]
|
|
Include = /etc/pacman.d/mirrorlist-archzfs
|
|
EOF
|
|
|
|
curl -L https://git.io/JtQp4 > /etc/pacman.d/mirrorlist-archzfs
|
|
|
|
#. Update pacman database::
|
|
|
|
pacman -Sy
|
|
|
|
testing repo
|
|
^^^^^^^^^^^^
|
|
Testing repo provides newer packages than stable repo,
|
|
but may contain unknown bugs.
|
|
Use at your own risk.
|
|
|
|
To use testing repo, uncomment lines in
|
|
``/etc/pacman.conf``.
|
|
|
|
archzfs package
|
|
~~~~~~~~~~~~~~~
|
|
|
|
When using unmodified Arch Linux kernels,
|
|
prebuilt ``archzfs`` packages are available.
|
|
You can also switch between ``archzfs`` and ``zfs-dkms``
|
|
packages later.
|
|
|
|
For other kernels or Arch-based distros, use `archzfs-dkms package`_.
|
|
|
|
#. Check kernel variant::
|
|
|
|
INST_LINVAR=$(sed 's|.*linux|linux|' /proc/cmdline | sed 's|.img||g' | awk '{ print $1 }')
|
|
|
|
#. Check compatible kernel version::
|
|
|
|
INST_LINVER=$(pacman -Si zfs-${INST_LINVAR} | grep 'Depends On' | sed "s|.*${INST_LINVAR}=||" | awk '{ print $1 }')
|
|
|
|
#. Install kernel. Download from archive if kernel is not available::
|
|
|
|
if [ ${INST_LINVER} == \
|
|
$(pacman -Si ${INST_LINVAR} | grep Version | awk '{ print $3 }') ]; then
|
|
pacstrap $INST_MNT ${INST_LINVAR}
|
|
else
|
|
pacstrap -U $INST_MNT \
|
|
https://archive.archlinux.org/packages/l/${INST_LINVAR}/${INST_LINVAR}-${INST_LINVER}-x86_64.pkg.tar.zst
|
|
fi
|
|
|
|
#. Install archzfs::
|
|
|
|
pacman -Sy zfs-${INST_LINVAR}
|
|
|
|
archzfs-dkms package
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
This package will dynamically build ZFS modules for
|
|
supported kernels.
|
|
|
|
Check kernel compatibility
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
#. Check kernel variant::
|
|
|
|
INST_LINVAR=$(sed 's|.*linux|linux|' /proc/cmdline | sed 's|.img||g' | awk '{ print $1 }')
|
|
|
|
#. Check kernel version::
|
|
|
|
INST_LINVER=$(pacman -Qi ${INST_LINVAR} | grep Version | awk '{ print $3 }')
|
|
|
|
#. Check zfs-dkms package version::
|
|
|
|
DKMS_VER=$(pacman -Syi zfs-dkms | grep 'Version' | awk '{ print $3 }' | sed 's|-.*||')
|
|
|
|
#. Visit OpenZFS release page ::
|
|
|
|
curl -L https://github.com/openzfs/zfs/raw/zfs-${DKMS_VER}/META \
|
|
| grep Linux
|
|
# Linux-Maximum: 5.10
|
|
# Linux-Minimum: 3.10
|
|
# compare with the output of the following command
|
|
echo ${INST_LINVER%%-*}
|
|
# 5.10.17 # supported
|
|
|
|
If it's not supported, see `Install zfs-dkms compatible kernel`_.
|
|
Otherwise, continue to next step.
|
|
|
|
#. Install kernel headers::
|
|
|
|
pacman -U \
|
|
https://archive.archlinux.org/packages/l/${INST_LINVAR}-headers/${INST_LINVAR}-headers-${INST_LINVER}-x86_64.pkg.tar.zst
|
|
|
|
#. Install zfs-dkms::
|
|
|
|
pacman -Sy zfs-dkms
|
|
|
|
#. Ignore kernel package from updates::
|
|
|
|
sed -i 's/#IgnorePkg/IgnorePkg/' /etc/pacman.conf
|
|
sed -i "/^IgnorePkg/ s/$/ ${INST_LINVAR} ${INST_LINVAR}-headers/" /etc/pacman.conf
|
|
|
|
Kernel must be manually updated, see `Kernel update`_.
|
|
|
|
Install zfs-dkms compatible kernel
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
#. Choose kernel variant. Available variants are:
|
|
|
|
* linux
|
|
* linux-lts
|
|
|
|
::
|
|
|
|
INST_LINVAR=linux
|
|
|
|
#. Install kernels available when the package was built. Check build date::
|
|
|
|
DKMS_DATE=$(pacman -Syi zfs-dkms \
|
|
| grep 'Build Date' \
|
|
| sed 's/.*: //' \
|
|
| LC_ALL=C xargs -i{} date -d {} -u +%Y/%m/%d)
|
|
|
|
#. Check kernel version::
|
|
|
|
INST_LINVER=$(curl https://archive.archlinux.org/repos/${DKMS_DATE}/core/os/x86_64/ \
|
|
| grep \"${INST_LINVAR}-'[0-9]' \
|
|
| grep -v sig \
|
|
| sed "s|.*$INST_LINVAR-||" \
|
|
| sed "s|-x86_64.*||")
|
|
|
|
#. Install compatible 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 zfs-dkms::
|
|
|
|
pacman -Sy zfs-dkms
|
|
|
|
#. Hold kernel package from updates::
|
|
|
|
sed -i 's/#IgnorePkg/IgnorePkg/' /etc/pacman.conf
|
|
sed -i "/^IgnorePkg/ s/$/ ${INST_LINVAR} ${INST_LINVAR}-headers/" /etc/pacman.conf
|
|
|
|
Kernel must be manually updated, see `Kernel update`_.
|
|
|
|
Kernel update
|
|
^^^^^^^^^^^^^
|
|
|
|
#. `Check kernel compatibility`_.
|
|
|
|
#. Replace check kernel version with ``-Syi``::
|
|
|
|
INST_LINVER=$(pacman -Syi ${INST_LINVAR} | grep Version | awk '{ print $3 }')
|
|
|
|
#. If compatible, update kernel and headers with::
|
|
|
|
pacman -Sy $INST_LINVAR $INST_LINVAR-headers
|
|
|
|
Do not update if the kernel is not compatible
|
|
with OpenZFS.
|
|
|
|
-git packages
|
|
~~~~~~~~~~~~~
|
|
|
|
Normal packages are built from
|
|
`latest OpenZFS stable release <https://github.com/openzfs/zfs/releases/latest>`__
|
|
which may not contain the newest features.
|
|
|
|
``-git`` packages are directly built from
|
|
`OpenZFS master branch <https://github.com/openzfs/zfs/commits/master>`__,
|
|
which may contain unknown bugs.
|
|
|
|
To use ``-git`` packages, attach ``-git`` suffix to package names, example::
|
|
|
|
# zfs-dkms
|
|
zfs-dkms-git
|
|
|
|
# zfs-${INST_LINVAR}
|
|
zfs-${INST_LINVAR}-git
|
|
|
|
Check Live Image Compatibility
|
|
------------------------------
|
|
#. Choose a mirror::
|
|
|
|
https://archlinux.org/mirrorlist/all/
|
|
https://gitea.artixlinux.org/packagesA/artix-mirrorlist/src/branch/master/trunk/mirrorlist
|
|
|
|
#. Check the build date of the
|
|
latest Arch Linux live image::
|
|
|
|
https://mirrors.dotsrc.org/archlinux/iso/latest/
|
|
https://mirrors.dotsrc.org/artix-linux/iso/
|
|
# archlinux-2021.01.01-x86_64.iso
|
|
|
|
#. Check the kernel version of the live image::
|
|
|
|
https://archive.archlinux.org/repos/2021/01/01/core/os/x86_64
|
|
https://archive.artixlinux.org/repos/2021/01/01/system/os/x86_64
|
|
# linux-5.10.3.arch1-1-x86_64.pkg.tar.zst
|
|
|
|
#. Check latest archzfs package version::
|
|
|
|
https://archzfs.com/archzfs/x86_64/
|
|
# zfs-dkms-2.0.1-1-x86_64.pkg.tar.zst
|
|
# zfs-linux-2.0.1_5.10.10.arch1.1-1-x86_64.pkg.tar.zst
|
|
|
|
#. Visit OpenZFS release page::
|
|
|
|
curl -L https://github.com/openzfs/zfs/raw/zfs-2.0.1/META \
|
|
| grep Linux
|
|
# Linux-Maximum: 5.10
|
|
# Linux-Minimum: 3.10
|
|
|
|
- If compatible, download the latest live image::
|
|
|
|
https://mirrors.dotsrc.org/archlinux/iso/latest/archlinux-2021.01.01-x86_64.iso
|
|
https://mirrors.dotsrc.org/artix-linux/iso/artix-base-openrc-20210101-x86_64.iso
|
|
|
|
- If not compatible, use an older live image and verify that it contains
|
|
a supported kernel using the above method::
|
