Okay, so my new 80 GB HD is installed and seems happy. Now I'd like to
make some changes to my original 20 GB hard disk. Originally, I left
/home and /usr in the root partition, and I'd like to split them out.
What's the easiest way to split an existing root partition into three
without ruining everything?
The plan I have at the moment is like this:
1. Boot from rescue diskette.
2. Mount first HD's root partition and a partition of equal or greater
size on the second HD.
3. Copy all files from root partition to second HD.
4. Unmount root partition.
5. Run cfdisk, destroy root partition, recreate new one along with
separate partitions for /home and /usr in the space of the original
root partition.
6. Create new filesystems in new partitions (mke2fs -j).
7. Mount new filesystems, copy files back from second HD.
8. Edit /etc/fstab to match the new reality.
9. Run lilo (/boot is a separate partition already, which won't change,
but this seems like a good idea and harmless at worst).
10. Reboot!
Does this sound good? Is there an easier way to split an existing root
partition? I have gparted, but have never used it, and I'm guessing that
in this situation it won't be useful (except perhaps as a substitute for
cfdisk in step 5) because of the need to move existing files from the
current root partition into the new ones.
Any comments?
Thanks,
Craig
