Adding Disk to double parity Array

Featured Replies

Hello,

I have and Array that has 4 Drives(4x 4tb). I want to add 2 new Drives (2x 16tb). But that is not possible... I can only add 1 Parity 

But I want to add 1 Parity and 1 Disk. How do I do that? Both drives are pre-cleard and zeroed.

Any data drive cannot be larger that the Parity drive.

 

As is, you cannot add data drives larger than 4TB.

You could use your 16TB as parity and assign the (old) Parity drives as Data drives.

Is there a mechanism to create a second array with the 16 TB as parity and another 16TB as the only disk (for now) then move all the files over then add the 4TB drivers under the new array?

No. You can do a parity swap though.

 

You will probably want to go single parity instead of dual at this point, right?

So I just change one parity drive with a 16tb disk and after that I add 4tb and 16tb as disks?

If you are going to run dual parity, both 16TB drives will need be parity drives.

 

The parity drives need to be as large or larger than your largest data drive.
