Upgraded to version 6.3.5 from UNRAID reboot put me into unmenu and I could not do anything.   So I did a fresh install by reformatting the flash drive. I added my plus key that I backed up. I assigned the drives started the array.  I selected the wrong drive for parity. Which means only one drive holds my files intact in a three drive system each 3 TB with one SSD as a cache. What do I do?

If the other 2 disks are unchanged you can try this:

 

-Tools -> New Config
-assign all disks, double check correct parity disk is the parity slot
-check both "parity is already valid" and "maintenance mode" before starting the array
-start the array
-stop array, unassign disk to rebuild (disk wrongly assigned as parity earlier)
-start array, check emulated disk mounts and contents look correct
-stop array, reassign disk
-start array to begin rebuild

Thank you back up and running.
