1st parity drive has errors, how to replace?

[ctviggen]

I am using version 6.4.0.  I have two parity drives, 6 disks, and a cache/hot spare.  I got a notice that Parity drive 1 has errors.  The parity drive and the cache/hot spare are the same size (3 TB).  The cache is formatted in btrfs. 

 

Is this process:

 

1) remove cache

2) "switch" parity drive 1 with cache (any formatting needed?)

3) buy 3TB drive as hot spare

4) toss old parity drive

 

Is this the current procedure for the parity:

Sorry if this is a simple question, but I only have to do things like this every 1-2 years, so I don't remember how it's done.  In fact, in the time the hardware as been working for unraid, I've replaced my home theater computer at least 3 times.  It's actually beginning to freak me out, and I'll be posting when I have time about what hardware to buy so that when mine finally goes down, I can effect a quick replacement.

It's not clear from your description that you need to replace parity at all.
