I modified my /dev/hda3 partition to occupy more physical space with
fdisk and dd by doing this:
dd if=/dev/hda3 of=<NFS_path>/hda3.img bs=4096
fdisk /dev/hda
I resized /dev/hda3 to be bigger
mkfs.ext3 /dev/hda3
dd if=<NFS_path>/hda3.img of=/dev/hda3 bs=4096

Everything on the system appears to work. My questions is:

Q1: Would there be any problem with the file system?

Suggestions? Comments?
