Быстрая настройка ZFS on Linux

wget https://download.zfsonlinux.org/epel/zfs-release.el7_6.noarch.rpm
yum install -y zfs-release.el7_6.noarch.rpm
yum update -y

For most users the kABI-tracking kmod packages are recommended in order to avoid needing to rebuild ZFS for every kernel update. DKMS packages are recommended for users running a non-distribution kernel or for users who wish to apply local customizations to ZFS on Linux.
