I currently have 4 data disks and 1 parity - all 1.5 EARS drives.
The 4th data disk is part of the array, but is empty and has never been written to (as far as I know).
I would like to remove this disk from the array and save it as a precleared disk to be added in case one of the other drive fails.
I would also like to upgrade the parity disk to a 2Tb EARS.
What is the best and safest way to accomplish both of these operations?
I was thinking I could:
1. Do a parity check
2. Remove both the 4th data disk and the parity disk and set aside.
3. Install new 2Tb parity disk and rebuild parity - (initconfig command ??)
If there was some problem during the process (such as a data disk failure) I could always shut down the array, re-install the original data disk 4 and parity disks and rebuild from there.
Does this sound like a valid plan?
Is there a better way to accomplish my goal?
I'm using version 4.6
