Help with disk swap procedures

[mattekure]

I just had a single disk fail.  It was old, so it will be replaced.    I currently have dual parity in the system and the failed drive is being emulated.

 

Drive situation

A - Parity 4Tb

B - Parity 3 Tb

C - 640 Gb - failed

D - new drive, 4Tb

 

 

I have purchased a new 4Tb drive for replacement.  I would like to make drive D, my new drive the second parity drive, and move drive B to the array.  

 

How do I do this safely and minimize risk of losing data?  

 

 

Edit - Nevermind, I found the procedure here: https://lime-technology.com/wiki/The_parity_swap_procedure

Assuming you're using the latest release, since I'm not certain when it became possible to do it on parity2, you can use the parity swap procedure:
