Upgrade Parity Disk Question

[Babar]

Hi all,

I am pretty excited about upgrading my parity disk to larger size. Its going into my HP Microserver gen8. The box allows 4 3.5" SATA disks, which are all currently occupied. I have gone through the documentation and I am still slightly confused.

 

I am sharing my disk assignment below.

 

 

Here is the target state. I will upgrade the parity disk from 16TB to 18TB. Once the array has copied parity data, I want to replace 4TB DATA disk with old 16TB PARITY disk. So the array sits like this. For OCD, I prefer to keep my PARITY disk in array bay 1 always. Yes I know.

 

 

What will be the shortest steps to achieve this outcome, while maintaining data.

Also, if possible, I want to keep the array available and functional while the Parity is rebuilt.

 

Thanks.

First upgrade parity, when that's done upgrade disk2.

Is there a way to upgrade parity disk without keeping array offline ?

The array is not offline while parity rebuilds.

Ok I have finally managed to preclear my new disk, so need to move to next step.

 

Question: Is there a way to copy the parity from previous 16TB disk to new 18tb disk, without having to rebuild parity again ?

Just let it rebuild.  If there's any issues with the new drive, you can always replace it with the old one via a New Config

Cheers, thanks.
