DKMS 或者 kABI-tracking kmod 风格的软件包储存在为 Centos 和 RHEL 提供的资源库中。 这些软件包随着新版本的发布而更新。 只有每个主要版本的当前存储库会使用新软件包进行更新。 软件包可用于以下配置:

EL Releases: 6, 7.9, 8.4

Architectures: x86_64

To simplify installation a zfs-release package is provided which includes a zfs.repo configuration file and public signing key. All official OpenZFS packages are signed using this key, and by default yum or dnf will verify a package’s signature before allowing it be to installed. Users are strongly encouraged to verify the authenticity of the ZFS on Linux public key using the fingerprint listed here.

Location: /etc/pki/rpm-gpg/RPM-GPG-KEY-zfsonlinux

EL6 Package: zfs-release.el6.noarch.rpm (zfs-0.8.x)

EL7.9 Package: zfs-release.el7_9.noarch.rpm (zfs-0.8.x)

EL8.4 Package: zfs-release.el8_4.noarch.rpm (zfs-2.0.5)

Archived Repositories: el7_5, el7_6, el7_7, el7_8, el8_0, el8_1, el8_2, el8_3

For RHEL/CentOS versions 6 and 7 run:

yum install https://zfsonlinux.org/epel/zfs-release$(rpm -E %distro).noarch.rpm
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-zfsonlinux

And for RHEL/CentOS 8 and newer:

source /etc/os-release
dnf install https://zfsonlinux.org/epel/zfs-release.el${VERSION_ID/./_}.noarch.rpm
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-zfsonlinux

After installing the zfs-release package and verifying the public key users can opt to install either the DKMS or kABI-tracking kmod style packages. DKMS packages are recommended for users running a non-distribution kernel or for users who wish to apply local customizations to OpenZFS. For most users the kABI-tracking kmod packages are recommended in order to avoid needing to rebuild OpenZFS for every kernel update.


To install DKMS style packages issue the following commands. First add the EPEL repository which provides DKMS by installing the epel-release package, then the kernel-devel and zfs packages. Note that it is important to make sure that the matching kernel-devel package is installed for the running kernel since DKMS requires it to build OpenZFS.

For RHEL/CentOS versions 6 and 7 run:

yum install epel-release kernel-devel zfs

And for RHEL/CentOS 8 and newer:

dnf install epel-release kernel-devel zfs


When switching from DKMS to kABI-tracking kmods first uninstall the existing DKMS packages. This should remove the kernel modules for all installed kernels, then the kABI-tracking kmods can be installed as described in the section below.

kABI-tracking kmod

By default the zfs-release package is configured to install DKMS style packages so they will work with a wide range of kernels. In order to install the kABI-tracking kmods the default repository must be switched from zfs to zfs-kmod. Keep in mind that the kABI-tracking kmods are only verified to work with the distribution provided kernel.

For RHEL/CentOS versions 6 and 7 run:

yum-config-manager --disable zfs
yum-config-manager --enable zfs-kmod
yum install zfs

And for RHEL/CentOS 8 and newer:

dnf config-manager --disable zfs
dnf config-manager --enable zfs-kmod
dnf install zfs

By default the OpenZFS kernel modules are automatically loaded when a ZFS pool is detected. If you would prefer to always load the modules at boot time you must create an /etc/modules-load.d/zfs.conf file:

echo zfs >/etc/modules-load.d/zfs.conf


When updating to a new RHEL/CentOS minor release the existing kmod packages may not work due to upstream kABI changes in the kernel. After upgrading users must uninstall OpenZFS and then reinstall it from the matching repository as described in this section.

Testing Repositories

In addition to the primary zfs repository a zfs-testing repository is available. This repository, which is disabled by default, contains the latest version of OpenZFS which is under active development. These packages are made available in order to get feedback from users regarding the functionality and stability of upcoming releases. These packages should not be used on production systems. Packages from the testing repository can be installed as follows.

For RHEL/CentOS versions 6 and 7 run:

yum-config-manager --enable zfs-testing
yum install kernel-devel zfs

And for RHEL/CentOS 8 and newer:

dnf config-manager --enable zfs-testing
dnf install kernel-devel zfs


Use zfs-testing for DKMS packages and zfs-testing-kmod kABI-tracking kmod packages.
