[vox-tech] I'm over my head - need a cookbook for transfering system to new disks

[Harold Lee]

I've had great success using parted / qtparted (GUI) to resize ext2/ 
ex3 and FAT partitions in Linux.

http://www.gnu.org/software/parted/index.shtml
http://qtparted.sourceforge.net/

 From the point of having Ghosted the data onto 300 GB partitions on  
the new drives, you could disable the RAID mirroring, resize them,  
and then rebuild the mirroring.
