Adding parity drives

[safiedin]

A quick question here.

 

I started using unraid about a year back, with 2 hard disk, both 4 TB.

so Disk A parity and Disk B storage.

 

I wanted to expand the storage. I could go with 4tb for Disk C. But thinking maybe its time to just add 2 parity as well.

 

Idea is to buy 4TB x 2 to replace Disk A.

 

And then Disk A to add on storage together with Disk B.

 

What is the safest way/method to do it without loosing data or messed up.

If they are all 4TB why replace parity? But if you want to just do a normal parity replacement, keep old parity intact during the re-sync, once done you can add old parity to the array.

so add disk C with A to become 2 parity

 

at the same time add disk D with B to become storage?

I do not think that Unraid will let you add a new parity and a new array disk in one step so you would need to do them one after the other (in any order).

Like mentioned you'll need to do one at a time.
