There may be good reason why RH doesn't support xfs, but if your
kernel already can handle xfs, would a rebuilt kernel help? As a test,
still with a SL5 32-bit system, I installed xfsprogs, then took an
unneeded partition (/dev/sda11 with the obsolete SL3.0.9) and did
mkfs.xfs -f -L test /dev/sda11
The result was an xfs partition that I could mount, write to, and read
from. I don't know what would happen if you tried mounting and reading
your USB 3.0 disk. But even if it can't be read with the standard kernel
I don't think harm would be done to the disk, especially if it's mounted
readonly ("-o ro").

Yes, I have intalled them... but, as Akemi Yagi says, XFS is disabled by
default on 32 Bits.
Now, according to this:
" *Yes, you can build your own 32-bit kernel with xfs enabled. However,
use xfs on 32-bit systems with caution because xfs has problems with
4K stack size (x86_64 uses 8k stacks). This is the main reason why
upstream does not support it. *"
It means, for instance, if my hard disk is external (USB 3.0) its lifetime
is warning?

On my SL5 32 bit system at home I don't use xfs, and lsmod showed no
xfs module loaded until I did 'modprobe xfs'. Then it was there, although
xfs cannot yet be used because xfsprogs isn't installed. If your kernel is
the standard one, you ought to already have xfs in it. Do you have the
xfsprogs rpm installed?

Nothing special. Only enable support to XFS filesystem. I have a hard disk
formated with XFS, and I need to back-up its content.
I read that repos for x86_64 have a kernel module, but I didn't found it
to
32 bit. Also, I wish to "perform" my OS :)

What makes you think you need a custom kernel?
I have a machine running XFS with the stock kernel.
[adamb@skeletor ~]$ cat /etc/issue
Scientific Linux release 6.1 (Carbon)
[adamb@skeletor ~]$ cat /etc/fstab
...
UUID=601f4a9a-8d68-4691-8a7a-**3082cb367cc6 /var xfs
defaults 1 2
...
Is there a specific feature of XFS you need that is unsupported?

Hi all
I have a laptop where I've installed SL 6.2. No problem at this time.
Now, I need to enable support to XFS filesystem, therefore a custom
kernel must be compiled.
My question is: What kernel can I use, or is "better": Oficial from RHEL
sources and SL, or sources from kernel.org? I would like to read your
advices :)
