How do I get a larger hdd into a raid 1 computer? On a computer with a 320gb hdd I want to make it to a 2tb hdd. It is in Raid 1 so do I just add a hdd and let it rebuild and then when that is done add the other 2tb hdd and let it rebuild thus now having a 2tb machine? I have never done this so can anyone help me out? Thanks.

You're running a PC with two 320GB HDs in a RAID 1 configuration and want to upgrade to two 2TB HDs in RAID 1, correct?
 
pretty much. then grow the raid.

as always backup first. i've done this with 8 drive proliant systems.

it may take a while to level each drive of course.

you could just backup the raid to the single 2TB, then (intel matrix) convert non-raid to raid. that would work too.
 
Been there - done that. As Emulex says, back up the current array to a single drive. Then shut down and replace the array drives with new ones. Rebuild the array (mirroring=RAID 1). Then proportionally clone or restore the backed up data to the new array. For backup, I regularly clone the RAID 1 array to an external USB drive. That can then be used to proportionally clone that same data to the new array. Not hard.
 
if you do not have a good raid controller (battery/flash back write cache) - a good battery backup - and shutdown system - strongly recommend never doing raid migrations.
 
So let's see if I get this right. I clone the hdd to one drive. I then stick it into the old drives place and then add the other hdd and let the raid take over?

If the statement is correct, you should reply with "yes".

You originally said...
"How do I get a larger hdd into a raid 1 computer? On a computer with a 320gb hdd I want to make it to a 2tb hdd."

That sentence sounds like you have a single 320GB HD and you want to move to a single 2TB HD.
But you're asking about a RAID 1 issue, which requires two drives per array.

I only asked you to confirm so that everyone reading this thread, trying to help you will have a clear understanding of your situation.
