I was having power issues with my server and it knocked out my parity drive. I rebuilt the server with a new parity drive and all was well for a few days. My server was only up for a few days before more power issues happened and now I can't boot to get a picture of the drive info (what drive is attached to what in unRAID). I am wondering if there is a way to pull the drive information from the config file so that when I upgrade my motherboard I won't run into any drive/data issues.

 

 

Edit: I swapped out the motherboard with no issues. The drives pulled back just like they were on the other board with a different layout. Thanks!

The only drives that really matter what slot they are assigned are the parity drive and the cache drive. Just assign ALL the drives to data slots, and leave the cache and parity slot empty. Start the array, and the drive that shows unformatted is the parity drive. You should be able to browse the rest of the drives to figure out which drive went where. Set a new config, and assign the drives to the correct slots now that you know which drive goes where, start the array with the checkbox to indicate that parity is already valid, and let it complete the parity check.

That's good to know. Thanks. I've only got one Hitachi drive in my rig at the moment, and that's my parity. I know which one my cache drive is too. Fantastic to know. Thanks!
