Parity swap with failed drive in array

[flying_rabbi]

Hi brains trust!

 

Scenario:

 

Have an 64tb array consisting of 8x8tb hdds. 1x parity, 7 array disks. 

 

Lately one of the drives in the array has been failing, and I've been constantly removing it and rebuilding it whilst I swap other variables around eg cables raid cards etc

 

On to the fun bit. I've bit the bullet, and ordered a 14tb drive to replace it, but, owing to the fact that my 14tb drive needs to be the parity, I'm hoping there's a way to shortcut the rebuild time. 

 

My idea at the moment is to rebuild my failing drive one last time, and then add the 14tb in as a second parity. Once that's done, remove 8tb parity and drop it in the array. Two full parity checks to complete the operation. 

 

Any thoughts on a better way? Had a look on the forums but didn't see my particular scenario.

You can use the parity swap procedure.

@JorgeB thanks mate, didn't look hard enough.
