Using old parity drive

[tucansam]

I've read here:

 

http://lime-technology.com/wiki/index.php/Un-Official_UnRAID_Manual

 

And have followed steps to upgrade my parity drive.  I now want to use my old parity drive to replace my smallest disk.  I've followed the steps and am at the point where I have upgraded my parity drive, reconstructed parity, ran a parity check, inserted my old parity drive in place of the disk I want to replace, powered up the machine, and configured the old parity disk in place of the old member disk in the drop down list.  I now have a red ball and the word "wrong" listed next to my old parity disk, and it lists the old disk below it.

 

Is this because unraid recognizes it as a parity disk?  Should I preclear or format it first?  Or is it just telling me it expected to see the old drive there, and I can just continue and start the array?

 

Obviously its my first time doing this 

 

Sorry if this is a newbie FAQ, I've looked around a bit and the above link is the only thing I immediately saw, and I'd like to get this resolved as I am currently unsure what will happen when I start the array.

 

Thanks to all.

Do you see this message: "Start will bring the array on-line, start Data-Rebuild, and then expand the file system."?

[tucansam]

Yep.  That message is there.

 

I'm good-to-go?

[dgaschk]

Yes.

[tucansam]

Now that its started and i have an orange ball next to the new (old) disk, I can click the "Rebuild" button?  Or is it doing this automatically behind the scenes?

[dgaschk]

Click the button.

Thanks for all the help.  Seems straight forward enough, just nerve wracking doing it for the first time!

I love dgaschk's minimalist yet highly informative posts in this thread.
