===== ZFS on Ubuntu Linux (12.04/LTS) =====


   apt-get install python-software-properties
   add-apt-repository ppa:zfs-native/stable
   apt-get install zfsutils ubuntu-zfs
   
edit ''/etc/default/zfs'' (if you want to automount ZFS on boot; disabled by default)


===== Memory Tweak =====

Per default ZFS uses as much memory as available for its ARC cache. It should not be less than 512MB and a good value is 1/4 of available memory. This property can only be set during module loading, to restrict how much memory should be used to 512MB:

   # echo "options zfs zfs_arc_max=512M" >> /etc/modprobe.d/zfs.conf
