This is my setup:
- Lenovo ThinkServer RD140
- IBM ServeRAID 8k controller
- Four Seagate Barracuda 1TB hard discs, organised in two RAID-1 arrays
Now the third disk is defunct (orange light flashing). I removed the third drive (hot-swappable) and replaced it with a spare 2 TB Seagate Barracuda (did a Google search and found that it's ok to use a larger drive). Nothing happened (i.e. no reconstruction).
I booted the server and opened to the RAID controller UI. It lists the first RAID as "Okay", the second RAID as "Critical" with a missing disk. It finds the new disk, but doesn't allow to associate the disk to an array.
I decided to format the new disk. After several hours, I got inpatient and rebooted the server. The first RAID came up, causing the (ESXi) server to boot regularly, the second RAID still is "Critical", the data is not accessable.
Now my plan is to discard the new 2 TB disk and get a new 1 TB disk as soon as possible. (Time matters.) Hopefully the RAID will rebuild with the right disk and be accessible again.
- What can I do to access the data on the second RAID?
- Have you got a recommendation how to proceed?
Thanks a lot for your help!
