Hi,

Have you read the documentation of fips?
I'm not sure myself now, but I now that fips is used before the installation to change the partitionsize of other OS-es.

But If you want to migrate your data from one disk to the other, you can just copy the data. The only thing you need to do the is to change your fstab and lilo-configuration.

Another option is to split up your directories over multiple partitions.

e.g.

/usr is on /dev/hdb1
/var is on /dev/hdb2
/ is on /dev/hda1

(in this case you only need to copy data and change fstab)

Let me know how you're going to solve it!

regards

I really only know of two tools

1. http://www.math.leidenuniv.nl/~buytenh/ext2resize/

2.
www.powerquest.com (Partition magic 4 and 5 comes with ext2fs resizing tools)

Personally i have used Pmagic which works well, but is commercial.

But wait.. NEITHER of these tools support spreading a filesystem over several devices. You said "Added 1.2Gig disk" is this a second disk, or did you just delete a 1.2 gig partition?

Why would you want to work with 1 big partition anyway? Now is the time to spread your data over several partitions. (which is a common way to do)

This is saver/better for your data. I don't know exactly, but it is preferred.
