Question on how Parity disks work


Recommended Posts

I still don't quite understand exactly how the parity system in Unraid works.

 

I have 8 5TB drives. I was planning on putting 6 of them into the main array, and then 2 of them into parity 1 and parity 2. 

 

Is this the proper way to set it up, then if any of the 6 main drives fail, the parity still covers the entire array?

Not precisely. If any TWO of the main drives fail they can be emulated and rebuilt. Parity encompasses all the drives, it requires the remaining drives to emulate the missing drives.

OK, that is perfectly fine. Thank you!
