I created an unRAID array with the basic software comprised of two data drives and a parity drive.  I only created the array and confirmed it was exported as a set of shares, I stored no data on it.

 

The motherboard I used to created the array subsequently wouldn't boot with the usb drive so I replaced it with an Asus P5PE-VM.

 

I've updated the P5PE-VM bios to the latest, and set it up to boot to the usb with unRAID, all works fine.

 

Stupidly, I didn't note the serial numbers of the drives and which slots they occupied nor did I save the .cfg file so I don't know which one was/is the parity drive.

 

I'd like to bring up the array on the new motherboard without having to re-create the parity drive again.

 

Is there a way to ID which drive was/is the parity drive via unRAID software or linux command?

 

thanks!

Well if you don't have the 'super.dat' file then there's no way to tell the new system that parity is "OK" and not to sync it.

 

If you had data you wanted to keep in this situation, you could do the following procedure to figure out which one was the parity disk:

 

Install just 2 of the 3 disks to your new motherboard.  Go to Devices and assign disk1 and disk2 but not parity.  Now go back to Main page an Start the array.  Since there's no parity, it will just try to mount the 2 data disks.  Whichever one comes up "unformatted", that was your previous parity disk.  If neither of them come up unformatted, then the one you didn't install was your previous parity disk.
