Changing Drives - aesser11/home-lab GitHub Wiki
Replacing a failed Data Drive
- Stop the array
- Unassign the old drive if still assigned (to unassign, set it to
No Device
) - Power down
- [ Optional ] Pull the old drive (you may want to leave it installed for Preclearing or testing)
- Install the new drive
- Power on
- Assign the new drive in the slot of the old drive
- Go to the
Main
→Array
Operation section - Put a check in the Yes, I'm sure checkbox (next to the information indicating the drive will be rebuilt), and click the
Start
button - The rebuild will begin, with hefty disk activity on all drives, lots of writes on the new drive and lots of reads on all other drives
Re-enabling a disabled disk
- Stop the array
- Unassign the disk from the slot
- Start the array in maintenance mode
- Stop the array again
- Reassign the drive to the same slot.
This will trigger a Data-Rebuild
The idea is to start the array temporarily with the drive "missing" so it changes from "disabled" to "emulated" status, then to stop it and "replace" the drive to get it back to "active" status.
