Hi forum,
I've got two 4Tb parity drives, that I want to replace with 20Tb drives. Nothing is broken, just planning to start buying 20Tb in the future so planning ahead.
I just did :
- Stop the array
- Remove parity 2 (4 Tb)
- Start the array
- Stop the array
- Added the new drive as parity 2 (20 Tb)
- Start the array
That's now rebuilding, ETA is 5 days with my services running (ouch).
In 5 days, I'll want to do the same with parity 1, but thinking about it now I'm not sure you can have parity 2 filled with parity 1 empty.
What would be my best bet ? I believe a "parity swap" procedure would keep the array offline for days, so that's out of the question. Should I have removed both parity drives now and rebuilt 1 instead of 2, leaving 2 out ?
Thanks
