Parity Upgrade (SOLVED)

[Spyderturbo007]

I found a bunch of threads and even the "Parity Swap Procedure" Wiki article.  However, none of them seem to cover a straight replacement of the Parity drive to a larger drive.  My current drive is 6TB and I want to upgrade the Parity drive to a larger 10TB drive.

 

What's the best way to handle the upgrade and maintain protection for the array during the upgrade?  Should the new Parity drive be precleared?

 

I read that parity drive 2 is different than parity 1, so I'm assuming I don't want to do it that way.  Can I just stop the array, shutdown the server, remove the current parity drive, assign the new drive as the parity drive and let it rebuild?

 

Since I'll still have parity drive 1, it would still keep the array safe during the rebuild.

Parity swap is not for upgrading just parity, for that you just assign the new parity and start the array, if you want to keep the old parity 100% valid in case something happens do the re-sync in maintenance mode.

So the swap is complete and parity has been rebuilt showing 0 errors.  Is a parity check necessary or is that implied when rebuilding parity?

 

The Dashboard says "Last check completed on Fri 11 Dec 2020 09:54:01 AM EST (today), finding 0 errors."

 

I just want to make sure I'm good before I add the old parity drive back to the array as a data disk.

Not necessary, but an option to make sure all went well.

Just wanted to update this and mark it solved.  The 10TB drive has been successfully added as the parity drive and the 6TB is now a data drive.  Thanks JorgeB for the help!
