Hi all. I am new to unraid. I was trying to upgrade my cache drive to a new one. After I started the array with the new cache drive, I noticed that I needed to backup the old cache drive first, so I stopped the array and selected the old cache drive. However, after started the array again, the old cache drive was unable to mount and shows "Unmountable: Volume not encrypted". I believe the old cache drive was originally formated as btrfs-encrypted. Is there still a way to mount the old cache drive, or the filesystem is already messed up and unreadable? Thanks for any help.
