(SOLVED)After Parity Swap Procedure, can I unassign the old parity drive?

[jena]

I read the Parity Swap Procedure carefully.

Just want to double check. 

 

Assume I have Data Drive A, Old Parity B, New Parity C.

After the Parity Swap Procedure - Step 14 , let's say for some reason (maybe B will be re-purposed in other places) I want to remove B.

So before step 15, I will unassign B and start the array, right?

 

PS:

The real reason that I take this way (instead of just replace B with C, let C rebuild off A) is:  my Data Drive A is the oldest. So I think by copying parity from B to C would have virtually zero stress on A. Otherwise if C rebuild from A, and A died in the process, then things will be very sticky?

Also in this way, I can familiar myself with the parity swap procedure. 

 

Suggestions and comments are welcomed.

Thanks!

You can't do that, parity swap procedure needs to be done from start to finish or it won't work, any change will abort it.

Oh, how I wish I had read this before I tried unassigning the data disk after the copy was complete but before the rebuild.  I can confirm that what JorgeB said above is correct.
