ZFS är filsystem kombinerat med volymhanterare. Det körs främst på BSD men finns även till Linux.
Installation
Ubuntu
sudo apt-add-repository -y ppa:zfs-native/stable sudo apt-get update && sudo apt-get -y install ubuntu-zfs
Fedora
sudo dnf install --nogpgcheck http://archive.zfsonlinux.org/fedora/zfs-release$(rpm -E %dist).noarch.rpm sudo dnf install kernel-devel zfs sudo /sbin/modprobe zfs
Konfiguration
Pool
zpool create POOL raidz1 \
/dev/disk/by-id/ata-WDC_WD.. \
/dev/disk/by-id/ata-WDC_WD.. \
