RAID 1 - Replace failing drive
I am helping a friend who wants to replace a failing drive in a RAID 1 Array.
The steps I have taken are:
1. Backed up the functional hard drive.
2. Removed and replaced the failing drive with an identical drive, same manufactuer and same size.
(the drive was formatted prior to installing)
3. Booted the machine and used Ctrl+I to enter the raid setup.
4. The options are numbered 1 through 6, but the #1 option, to create a RAID 1, is unavailable.
(it's dimmed out)
5. The 2 drives show with the original drive listed as Member Disk and the new drive Non-RAID.
My question is how can I enable the number 1 option? I do not want to do a format of the functional drive, but just replace the failing drive and have a RAID 1 Array.
