[SLL] Rearranging partitions on RAID1

[Mike Stunes]

I've got two drives in RAID1 on my box at home. When I set this box up, 
being unfamiliar with partitioning anything bigger than 40GB, I 
allocated / and /home about half-and-half, not realizing that everything 
in / would take up much less space than I thought it possibly might 
take, so now I've got / at about 6% full, and not growing, and /home 
about 26%, with lots of potential to grow much bigger. I'm trying to 
figure out the best way to rearrange these, keeping in mind I've got a 
RAID1 I can't screw up, and I would rather not risk all of my data in 
the process, naturally. I figure I can either use gparted on both 
drives, or use gparted on one drive and dd it to the other drive, or 
just completely back everything up and recreate the partitions, RAID, 
and filesystems from scratch. Anybody have any thoughts on the best and 
safest way to do this? Thanks in advance!
