I believe part of the problem has to do with what the kernel believes the disk
geometry is.
With the 2.4 kernel, the disk geometry comes back as the following:
root# cat /proc/ide/hda/geometry
physical 77545/16/63
logical 4865/255/63
With the 2.6 kernel, the disk geometry comes back as the following:
root# cat /proc/ide/hda/geometry
physical 16383/16/63
logical 65535/16/63
After re-imaging the client with SI 4.0.2 ( which is a 2.6 ) kernel, I'm now
getting errors
from parted after the disk geometry.
I tried to make the hda2 partition smaller, but still getting the same problem
of / being
reported as only having about 130MB of space used.
Oh, I have found that when I hit 200MB of space used, even though I have plenty
of space
left free, I get out of space errors when I try to create any new files or
directories.
I tried to modify the boel_binaries tarball from SI 4.0.2 to include an older
version of parted,
and any necessary libraries, from a running SLES 8 system to see if I could use
the older
version of parted to get around the problem. No dice.
Any thoughs/ideas??

The client, when re-imaged should be using about 800MB of space. But on
re-image and reboot,
the client status that only 134MB of space is being used under /, but yet all
800MB of data is there.
It's interesting that the 134MB of space being report is the size of the swap
partition, /dev/hda1.
The following is the df, du and partition table output for the client after
re-imaging and rebooting.
root# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hda2 38338176 134384 36256300 1% /
shmfs 255904 0 255904 0% /dev/shm
root# du -sk /
768167 /
root# parted /dev/hda print
Warning: Unable to align partition properly. This probably means that another
partitioning tool generated an incorrect partition table, because it didn't
have the correct BIOS
geometry. It is safe to ignore,but ignoring may cause (fixable) problems with
some boot loaders.
Ignore/Cancel? ignore
Disk geometry for /dev/hda: 0.000-38166.679 megabytes
Disk label type: msdos
Minor Start End Type Filesystem Flags
1 0.000 129.700 primary linux-swap type=82
2 129.700 38166.679 primary ext3 type=83
Information: Don't forget to update /etc/fstab, if necessary.
The OS states that there is 36GB of space free. But if I attempt to apply
various OS and application fixes,
at some point I start getting out of space messages.
If I try to remount /dev/hda2 on /mnt, it still reports the 134MB space being
used.
Not sure what else I can do, other then going back to an older version of SI.
My only problem is that part of the reason I went with 4.0.2, aside from being
the latest stable version,
is that it includes support for the natsemi network card and handles long
network runs.
We had to create a custom boel_binaries tarball for the older version of SI we
are running to work with
out systems. Only problem is that it doesn't have the necessary support for
the long network runs.

Yes I have updated the kernel to the latest version supported by the product.
