How to replace hard drive on Ubuntu.

Hello,

I have a linux box running off of Ubuntu 12.04.4. Its on a raid 5 configuration and 1 of my hard drives went bad. I replaced it with a new hd, but for some reason its not taking it.

Are there some commands I have to run to have the system accept the new hard drive?

ps. I'm new to linux so please try to keep the answers as simple as possible.

Thanks in advance.

What do you mean by this? Do you get an error?

Can you share some details on which hardware you have, controller etc?

Are you using the RAID controller for your array, or Linux software RAID?

Hi, I believe the raid is on the HP P410 controller.

If your controller is used,then Ubuntu has absolutely nothing to do with it. Just use the controller's utility (usually a short-cut key combination at bootup) to get into it's configuration.

As I said above, use the controller's utility at bootup to check it's state and recreate the array.

Wouldn't I loss my data, if I recreate the array?

Not if you do it properly. You probably just have an option to add the new disk to the array, and then it should rebuild, or on some controllers, you assign it as a hot spare, and then it should also rebuild. You just have to make sure you don't select the wrong disk, and maybe check on the controller's manual.

Either you need HP driver installed  in system or bless disk replacement in BIOS/Smart Array diagnostics.
