How do I grow a raid 5 system?

[n2jesus]

Hi all,
One of our servers has a sata raid 5 on an adaptec raid controller. Within a year or so I will need to make the hard drive space bigger.

I'd like to think that it is as simple as replacing a hard drive with a bigger drive one at a time, let the raid rebuild, then replace another drive. Then repeat until all the drives have bee replaced. At the end you have twice the volume and the raid is using it all.

I'm guessing it's not that easy though, so how do you do it without backing up everything, build a new system and restoring?

Thanks for any advice,

Jim

This is the network appliance hardware forum, you'll have a better chance getting an answer in another forum , that is related to "plain" disk and raid solutions.
