Great, I will follow those steps 😎.
Nope, nothing set up.
I found other methods, but I'm fine with this approach.
My plan is pause the usage of the server, copy the data, remove the drives and resync parity.
----
I would like to raise two additional questions:
[1 - During the copy process] How "important" is the comparison step (rsync -narcv)? I am looking for a way to speed up the process and I cannot fully understand the verify part.
[2 - Rebuild partiy] Do the old drives (e.g. drive #07) have to stay at their old slots? Or can I rearange them by size? My idea: First 8TB drives and then followed by 10TB drives
