How can I change the persistent home file size?!

I need a bigger knoppix.img persistent home. How can I resize it?

assume it is on /mnt/hda1,

1. dd of=/mnt/hda1/new_home if=/dev/zero bs=1M count=50

this create a new 50M file

2. mke2fs -j /mnt/hda1/new_home

this create a new ext3(or you can choose other fs) on new_home

3. mount /mnt/hda1/new_home /mnt/test -o loop

mount it to a mount point at /mnt/test

4. cp -dRp /home/* /mnt/test/*

copy everything over

5. mv /mnt/hda1/knoppix.img old_home; mv /mnt/hda1/new_home knoppix.img

replace it. when everything is cofirmed work, you can delete the old one.

Ok, that's what I already tried! The problem comes with the actual copy command.. I first used "cp -a".. It didn't work. Not all files were copied.. I tried your "cp -dRp" and it didn't work either! There are some files that just won't get copied! I tried to boot Knoppix without persistent home, then mout knoppix.img in some dir, new_knoppix.img in another dir... but I can't copy (all) the files from one dir to another! And those are just normal files! That's strange...
Any ideas?!..

well, try tar then. tar is supposed to be the right tools to do this kind of thing(in the past, backup everything to a tape).

or may be 'rsync'.

I used KDE to resize my Knoppix 3.2 persistent home. Here's the process:
Copy your personal files from the knoppix home to a folder on a hard drive mounted read/write.
Reboot Knoppix without mounting your Knoppix home (no home=scan entry).
Unmount the hard drive you will use for the persistent home.
Go to kmenu, knopppix, configure, and make a persistent home of the new size you want.
Knoppix will make a new sized home over your old home. Be patient, it can take a while.
When the question about encryption comes up, it's done.
Reboot with mounting of the Knoppix home; and the new space should be there.
Go to kmenu, system, info center, storage devices to check the size and free space.
