XFS Issues

["Norbert Veber" <nveber@xxxxxxxxxxxxxxxxxx>]

Hi,

I have been running the 1.0 release for some time, with the 2.4.3 kernel,
and all partitions formatted to xfs (except /boot since I'm using grub, not
lilo).

While upgrading to the 2.4.6 patch, and trying to delete the old source
tree, I came across this:
root@pyre[/usr/src]# rm -rf linux-2.4.3-XFS/
rm: cannot remove directory inux-2.4.3-XFS/fs/cramfs': Directory not empty
rm: cannot remove directory inux-2.4.3-XFS/fs': Directory not empty
rm: cannot remove directory inux-2.4.3-XFS': Directory not empty
root@pyre[/usr/src]# ls -al linux-2.4.3-XFS/fs/cramfs/
total 0
drwxr-xr-x    3 root     root          110 May 24 20:48 .

It appers to be empty, yet it cannot be removed.

I have since upgraded to 2.4.6-XFS, but I am still unable to delete the
files.

Another thing I noticed with both kernels is that the output of the "free"
command always shows "buffers" as either 4 or 8.
ie.
pyre[~]# free
             total       used       free     shared    buffers     cached
Mem:        255580     251312       4268          0          4     214100
-/+ buffers/cache:      37208     218372
Swap:       789216     132180     657036

Is this normal?  Does the XFS kernel not use buffers, or, is the output just
wrong?

Thanks,

Norbert
