============================ 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) 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
|
||||

|
||||
|
||||
> # Create a 100G block device named 'fish' in the 'tank' zpool.
|
||||
> zfs create -V 100G tank/fish
|
||||
> zfs list

||||

Native ZFS for Linux! ZFS is an advanced file system and volume manager
|
||||
which was originally developed for Solaris. It has been successfully
|
||||
ported to FreeBSD and now there is a functional Linux ZFS kernel port
|
||||
too. The port currently includes a fully functional and stable SPA, DMU,
|
||||
and ZVOL with a ZFS Posix Layer (ZPL) on the way!
|
||||
|
||||
Documentation for building, configuring, and using ZFS can be found at:
