Upgrading an existing RAID HDD

I have a server with a RAID type 1 array of 2 40 GB hard drives. I want to upgrade those HDDs. Is there any way to do this easily?

I was thinking of buying 2 200 GB 7200 rpm drives with 8mb cache
swapping out one, synching it, and then swaping out the other and synchng. Would that work?

Hmm, I would think that you might need a new Raid controller card for the new drives... We recently did this at my work, we went from 3 drive set to a 6 drive set, we had to get a new raid controller card, we backed up the old system onto a tape then restored it.

It should, as long as it lets you use the entire new drive formatted as a 200GB drive and keeps it that way and doesn't make it look like a 40GB when it's doing the remirroring.

The documentation says it will 200 to be a 40, but I was hoping when I add the second 200, they would both go back to 200. I can't to find any resources on this type of thing anywhere.

I think if it makes the 200 look like a 40 when you put the 2nd 200 in there it will make it look like the other drive -- a 40.

Backup and restore to another drives sounds like the best way to go. BTW, I've heard Ghost isn't able to restore to some RAID controllers.
