============================ ZFS QUICK START ============================
1) Build the SPL (Solaris Porting Layer) and install it. This package
provides several Solaris APIs used by ZFS and is a required dependency.
Before building ZFS build this package and install the resulting rpms.
> tar -xzf spl-x.y.z.tgz
> cd spl-x.y.z
> ./configure --with-linux=<kernel src>
> make
> make rpm
> sudo rpm -Uvh *.<arch>.rpm

2:spl-modules-devel ########################################### [ 67%]
3:spl-modules ########################################### [100%]
2) Build ZFS and install it. This package provides the native port of
ZFS for Linux including all kernel modules and command line utilities.
Note it is important that you have installed spl-module-devel package
from step 1) before attempting to build ZFS.
> tar -xzf zfs-x.y.z.tgz
> cd zfs-x.y.z
> ./configure --with-linux=<kernel src>
> make
> make rpm
> sudo rpm -Uvh *.<arch>.rpm

3) Enjoy ZFS on Linux! Currently only the ZVOL is fully functional
but work on the ZPL is underway. Why is just having the ZVOL still
useful you ask? Well here's an example of what you can do today using
just the ZVOL:
> # Create the 'tank' zpool containing a raidz vdev spread over 4 devices.
> zpool create tank raidz /dev/sdb /dev/sdc /dev/sdd /dev/sde
> zpool list
NAME SIZE USED AVAIL CAP HEALTH ALTROOT
tank 1.81T 132K 1.81T 0% ONLINE -
> # Create a 100G block device named 'fish' in the 'tank' zpool.
> zfs create -V 100G tank/fish
> zfs list
NAME USED AVAIL REFER MOUNTPOINT
tank 100G 1.24T 26.9K /tank
tank/fish 100G 1.33T 23.9K -
> # Partition 'tank/fish' as if it were a normal block device.
