zfs インストール
[root@centos7 ~]# yum install -y http://download.zfsonlinux.org/epel/zfs-release.el7_4.noarch.rpm
[root@centos7 ~]# gpg --quiet --with-fingerprint /etc/pki/rpm-gpg/RPM-GPG-KEY-zfsonlinux
[root@centos7 ~]# cp -ip /etc/yum.repos.d/zfs.repo /etc/yum.repos.d/zfs.repo_20190315
[root@centos7 ~]# vi /etc/yum.repos.d/zfs.repo
以下に変更
[zfs]
enabled=0
[zfs-kmod]
enabled=1
[root@centos7 ~]# yum install -y zfs
ここではまだうまくいかない、一部のパッケージを削除して再インストール
[root@centos7 ~]# yum remove zfs zfs-kmod spl spl-kmod libzfs2 libnvpair1 libuutil1 libzpool2 zfs-release
[root@centos7 ~]# yum install -y http://download.zfsonlinux.org/epel/zfs-release.el7_4.noarch.rpm
[root@centos7 ~]# yum autoremove
[root@centos7 ~]# yum clean metadata -y
[root@centos7 ~]# yum install -y zfs ※かなり時間がかかる 30分ぐらいか
[root@centos7 ~]# zfs list
