(solved) replacing 2 drives, best order of operations?

[VFRLuke]

Hello, I have recently started getting some smart errors on some of my old 2TB drives and I picked up a couple of 12TB drives to replace them.  They are over 10 years old.

 

Obviously I want to assign one new drive as the parity, Use the old parity 8TB drive and the other new 12TB drive to replace disks 3 and 4.

 

I have the new drives in and precleared.

 

I was thinking this order

1.  Replace the parity drive and let it rebuild

2. Replace disk 3 with the other new drive

3. Preclear the old parity drive and replace disk 4 with it

 

Would there be a better way of doing things?  I wasn't sure if the parity swap procedure was appropriate since I have all drives currently installed.

 

Thanks in advance for your help,

Luke

Since disk3 has pending sectors best to get it out first.

 

I would do parity swap with disk3 then replace disk4.

Thanks for the reply.  I'll start that tomorrow.

Did the parity swap and that went perfectly, thanks.
