I just want to be clear, the article on the wiki talks about replacing a data drive and the parity drive, I just want to swap out my parity drive with a larger one, so do I:

 

1.Stop the array

2.Unassign the existing parity drive.

3.Start the array (checking the box, yes I want to do this)

4.Stop the array.

5.Power down.

6.Physically swap the old parity drive with the new larger one.

7.Reboot, assign the new drive as the parity drive.

8.Start a parity sync.

 

Is that it?

Pretty sure you don't need 1-3, just start at 4.

Is that right? I can skip 1-3?

If you skip 1-3 I believe you'll get a "wrong disk" message when you Start the array with the new drive.  At some point you need to unassign the old drive; Start the array (so it shows a "missing" drive); then Stop the array and assign the new drive; and then Start the array and it will do a new parity sync.    You could start with #4, then at #7 you would unassign the old parity disk; start the array; stop the array; and assign the new drive.

 

Note that before you do anything, you should change the settings so the array doesn't auto-start.

 

Note that since you're replacing the parity drive, you could also simply do a New Config; assign all the data drives and the new parity drive; and then Start the array.

 

" Note that since you're replacing the parity drive, you could also simply do a New Config; assign all the data drives and the new parity drive; and then Start the array."

 

So what, stop the array, shut down, swap out the parity drive with the new one, boot up (make sure array does not auto start) and then do 'new config' assign all the data drives and the new parity drive?

Yes, that's it.

 

Where is the setting to stop the array from auto starting?

Settings - Disk Settings

 

The first setting is "Enable auto-start" => change it to No

 

I'm pretty sure that anytime I have replaced a drive, whether parity or data, when unRAID boots up without the old drive it says the old drive is missing, and then I just select the new drive, and it says it will rebuild when I start, whether parity or data has been replaced. I don't think it is even necessary to unassign the drive even if you leave it in. You can just assign the new drive. I think the only time the wrong disk comes up is when you are in some situation where there are too many missing or wrong disks so a rebuild isn't possible.

 

So I don't think those extra steps are necessary, and I don't think a New Config forcing you to reassign everything is necessary either.

I'm with you trurl, never mess around with new config unless you have to.

Considering this is a procedure that many users will eventually need to perform I'm surprised there's no wiki page to cover it. There's a page for replacing a data disk and for the more complex "swap disable" process. Perhaps replacing the parity disk is thought to be so similar to replacing a data disk that a separate entry is deemed not necessary. Perhaps a note should be added to that page?
