I have a very low-end UNRAID system, all disks are plugged into the 6 sata ports on the motherboard, nothing fancy, but it seems to fly along, I don't use docker and whatnot, just straight-up storage.

I recently (parity is still rebuilding as I type) decided to upgrade the parity disk from 2 TB to 4TB, and I seem to be getting a very good speed on the rebuild, the lowest I've seen was 90 MB/sec, but most of the time it's been at 150MB/sec, it's been running 7hrs 41mins and says it has around 2hrs 30mins remaining.

 

I'm going to add the old parity drive to the array for storage, do I need to do anything to it or can I just add it? What I mean is, will UNRAID give a crap if it was formerly a parity disk.

Just add it, it will be cleared and then you can format it.

It completed the parity rebuild 10hrs 30mins, not too shabby.

 

Thanks for the reply.
