This seems like it should be relatively simple, but it's stumping me. I moved my entire setup to new hardware, including a new HBA, new motherboard, etc. I kept my same flash drive, backed up everything on the flash, and wiped it and reloaded it with the intention of reimporting all my disks based on their serial numbers and such, since everything is moved around.

 

The problem is, I can't seem to find my screenshot of which disks are which.

 

How can I, ideally from the command line, identify which of my disks is the parity disk? I'm considering just making a bunch of mount points and mounting each disk as read only, and seeing which ones have useful data on them. But I have to imagine there's an easier way. I poked around my backup of my flash drive, but I'm not seeing a file that indicates which drive is mapped to which disk slot.

 

Any ideas?

Assign ALL of your disks to the array WITHOUT a parity disk => then see which disk shows as unformatted.

 

That's your parity disk.

 

Now do a New Config and assign every disk EXCEPT that one to the array (again WITHOUT a parity disk) and confirm that there are no unformatted disks.    Start the array and confirm you can browse all your data okay.  Then Stop it; assign the parity disk; and Start it up and let it do the initial parity sync.

 

Another way is to find your super.dat, in the config folder, and look inside it.  The first drive is the parity drive.  If you had a second parity drive, it would be the 29th, near the bottom.

 

Another way is use the strings command at a command line ->  strings  path_to_it/super.dat

First drive is the parity drive.
