Centos8安装ZFS

查看当前centos版本号

cat /etc/redhat-release

CentOS Linux release 8.3.2011

然后

sudo dnf install https://zfsonlinux.org/epel/zfs-release.<dist>.noarch.rpm
gpg --import --import-options show-only /etc/pki/rpm-gpg/RPM-GPG-KEY-zfsonlinux

其中<dist>换成版本号，比如我这个就是el8_3。

DKMS

yum install https://dl.fedoraproject.org/pub/epel/epel-release-latest-8.noarch.rpm
sudo dnf config-manager --set-enabled powertools

（上面这段是不是可以不要？）

sudo dnf install epel-release
sudo dnf install kernel-devel zfs

要等好久。

插入内核模块

/sbin/modprobe zfs

检查一下是否安装成功：

sudo zfs list

显示这个就说明装好了。

no datasets available

卸载

sudo yum remove zfs-release
