Hi,
This has been asked a number of times before and I've read through a lot of threads, but its my fist time doing this and wanted to double check for sanity.
I have an array currently running with 3 x 4tb drives and 1 x 8tb parity drive.
Thanks to black friday sales I now own 2 x 18tb drives.
I want to add these to the array whilst removing 1 x 4tb drive (I want to put it in another machine), giving the following: 1 x 18tb parity, 1 x 18tb + 1 x 8tb + 2 x 4tb array.
Is the most sensible way to do this:
Run a Parity check.
Stop the array.
Power down.
Remove Parity drive (doesnt need to be physically removed, I will just disconnect it) and install 1 x 18tb drive.
Power on.
Assign 18tb drive as Parity.
Start the array.
Build Parity drive.
Stop the array.
Power down.
Remove 1 x 4tb drive, install 1 x 18tb drive and reinstall the 8tb drive.
Power on.
Assign new drives to the aray.
Start the array.
Data should be rebuilt, leaving a fully working system as described above?
I guess this might not be the most efficient way, but by doing it stepwise it makes me slightly more comfortable and I am happy with any additional time it needs. I feel like I am missing a step when I remove the 4tb drive but cant work out what that is.
Thanks
