| | If you have never configured and compiled a new linux kernel
you might consider reading the Linux Kernel HOWTO before doing this
step. It can be found at the
Linux Documentation Project (LDP)
or one of its mirrors.
|
After having downloaded the cvs source tree the actual kernel
source will be in /usr/src/linux-2.4-xfs(-beta)/linux, so you should
switch to that directory before running the make config command of
your choice. The main things that must be included in your kernel
to provide XFS support are "Page Buffer support" and (duh)
"SGI XFS filesystem support." Both options are available
in the "File systems" section of the kernel configuration.
You will need to have "Prompt for development and/or incomplete
code/drivers" selected under "Code maturity level options"
for those options to be available to you. Optionally, you may also
want to select "Enable XFS Debug mode" and "Enable
XFS Vnode Tracing" under "SGI XFS filesystem support."
These options may slow your XFS implementation some, but may be useful
in tracing the cause of a crash if a crash occurs.
As with any kernel build, the following commands must be run
to actually build the new kernel:
$ make dep
$ make bzImage
$ make modules
|
Again this is standard for any kernel installation:
$ make modules_install
$ cp arch/i386/boot/bzImage /boot/vmlinuz-2.4.0-XFS
|
Add a new image section to your lilo.conf file similar to the
following:
image=/boot/vmlinuz-2.4.0-XFS label=xfs read-only root=/dev/hda2
|
The "root=" line should match the "root="
line from the existing image sections in your lilo.conf file. Don't
forget to run lilo when you're through editing lilo.conf to make
the changes effective.
There are a number of tools that come with the XFS filesystem that allow
you to build and manage your XFS filesystems that must be built as well.
These tools are in the /usr/src/linux-2.4-xfs(-beta)/cmd/xfsprogs directory.
| Note |
|---|
| | These tools rely on the /usr/lib/libuuid.a shared library. If you
do not have this library installed you will need it in order for
the XFS utilities to compile. You can find the rpm package for
your version of Linux from Rpmfind.net by searching for "/usr/lib/libuuid.a." The debian package that contains libuuid is uuid-dev. There will no doubt be other distributions that package this library in another place. A good way to find the correct package on those distributions is to search on the Google Linux search engine.
|
Change to that directory:
Build and install the xfs utilities:
| Note |
|---|
| | Unless you changed the default label to boot in your lilo.conf
file you will need to enter "xfs" at the "LILO Boot:"
prompt in order to boot the new kernel image.
