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
# https://stackoverflow.com/a/25500911
rpm -e --nodeps $(yum list installed | grep zfs | awk '{ print $1 }')

sudo systemctl daemon-reload
sudo systemctl reset-failed
