I would look at the contents of /boot and remove any unused kernel
images before trying to grow the filesystem. Much less painful.

That only shows current disk usage, you need to find out how much
unallocated space is left. (df and du only shows allocated space)

Try fdisk -l /dev/hdX or sdX where X is the disk and look for free
space. df -h gives easier to read info:
[root at linus root]# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda3             191M   99M   92M  52% /
/dev/hda5              10G  320K  9.9G   1% /backup
/dev/hda1              11M  4.9M  6.1M  45% /boot
/dev/hda6              10G  1.6G  8.4G  16% /home
none                  125M     0  125M   0% /dev/shm
/dev/hda11             97M  1.9M   95M   2% /tmp
/dev/hda7             4.0G  1.8G  2.2G  43% /usr
/dev/hda2             348M  192M  156M  55% /usr/local
/dev/hda9             191M   53M  138M  28% /var

What's the output of "mount|column -tx"? It will show the filesystem type.

| [root at server root]# lsmod
| Module                  Size  Used by    Not tainted
| autofs                 11172   0  (autoclean) (unused)
| e1000                  50912   1  (autoclean)
| usb-ohci               20192   0  (unused)
| usbcore                71072   1  [usb-ohci]
| ext3                   64768   6
| jbd                    47892   6  [ext3]
| aacraid                28532   7
| sd_mod                 12832  14
| scsi_mod              104800   2  [aacraid sd_mod]

Since the ext3 module is loaded, it may be an all ext3 filesystem. If
so, good luck. I don't know of a native ext3 filesystem tool to grow it.
