I wanted some input before I attempted this.
My scsi array consists of 12 72gb disks. If I start replacing failed disks
with larger disks, can I grow the array to fill the space? Once all the
disks are replaced with larger drives, would I : umount the raid array, make
all the
drives as failed except for one, grow the partitions on that one drive, then
raid hot add the rest of the drives?
B.

You need to supply some more information first. Which RAID type are you
using, RAID 0,1,4,5 or a combination like 0+1, or 5+1. In case you
aren't sure; 0=Stripe across all disks, no fault-tolerance; 1=Mirrored
drive pairs, a 1:1 drive ratio; 4=Striping across all drives except one
which is reserved for parity only, 5=Striping across all drives with
parity across all drives; 0+1=Striping across 1/2 of the disks and
mirroring the stripe to the other half; 5+1=Two RAID 5 sets that are
mirrored.
