Here's my current array layout:
P - 12TB
1-4 - 12TB
5 - 5TB
6 - 2TB
What I'm wondering is - if either drive #5 or #6 dies and I got a 14TB drive or larger replacement, what's the best way to incorporate that new drive into the array?
I know that in my case for a healthy array I would just simply swap the parity drive for a 14+TB drive, but at the moment I can only think of replacing the data drive with the 14TB drive and losing the 2TB extra capacity if one data drive has already failed.
Is it possible to shut the array down and clone the parity drive to the 14TB drive so that I wouldn't have to do a full parity calculation, and put the old 12TB parity in place of drive #5 or #6? Or if I can't clone it, how can I put the new 14TB drive in as parity and put the 12TB parity as a data drive, assuming 1 data drive is dead?
Thank you.
