[linux-dvb] XFS / Linux 2.4.6 HOWTO and report.
Hi,
this may be slightly off topic, but as XFS has been discussed
here several times and a few questions were left open, I think
I should contribute my experience.
I had both reliability (data loss after power failure, kernel
panic during a 2-week vacation) and performance (slows down a
lot when the disk gets full) problems with Reiserfs, so I
decided to install Kernel 2.4.6 and XFS. Here is what I did:
* Distribution: SuSE 7.2 with hand-configured kernel.
* Downloaded kernel 2.4.6 from kernel.org.
* Downloaded linux-2.4.6-xfs-07052001.patch.bz2 from
ftp://oss.sgi.com/projects/xfs/download/patches
* Downloaded xfsprogs-1.2.0.src.tar.gz from
ftp://oss.sgi.com/projects/xfs/download/Release-1.0/cmd_tars
* Unpacked kernel 2.4.6 into /usr/src/linux-2.4.6
* Applied linux-2.4.6-xfs-07052001.patch.
* copied .config over from my old kernel directory, ran
make oldconfig
and answered all questions with <cr>
* Ran
make xconfig
and enabled xfs.
* Changed the link /usr/src/linux, so it now points to
the new directory /usr/src/linux-2.4.6.
I do not know if that is recommended, but so far it did not hurt.
* Compiled, installed and booted the new 2.4.6-xfs kernel.
* Compiled and installed xfsprogs-1.2.0.
* Ran
mkfs.xfs /dev/hdg1
* Mounted /dev/hdg1
* Copied 66GB of vdr movies to the mounted disk.
% df -hT /video
Filesystem Type Size Used Avail Use% Mounted on
/dev/hdg1 xfs 93G 66G 28G 70% /video
* Ran configure, make clean and make install in my
lirc directory.
* Ran make clean and make insmod in the DVB/driver directory.
* Started vdr.
All of these steps worked without any problems, except for the
fact that "make bzlilo" intalled System.map and vmlinuz on "/"
instead of "/boot". I moved them to /boot manually. Does anyone
know what I did wrong? Is this a "feature" of 2.4.6?
Here are some additional links:

I have been working with XFS under IRIX for about 7 years now
and there has never been so much as a glitch with it.
For the less adventuresome user: I heard that XFS 1.0.1 will
be out within a week or so. It should provide a complete Linux
2.4.5 source tree with the patch already applied.
For the more adventuresome user: they also provide a CVS tree
that keeps up with the latest kernel.
Hope that helps,
Carsten.
P.S.:
I am using vdr 0.8.3 with a CVS snapshot of the DVB drivers
taken on June 19th. After reading here that newer CVS versions
of the DVB drivers do not work with vdr, I did not dare to
install a later driver version. Does anyone know what the
latest version is that does work with vdr 0.8.3?
I guess I will also post that question separately.
