I used method 3 and it worked like a charm. Removed the USB and the files/folders I created are still there. Everything stays mounted and I can create files/shares etc. But when I try to create a new MySQL instance I can't see the share created, it only lists the two physical arrays that I have. Under filesystems it lists the drive there but as /dev/disk/by-uuid/diskUUID and as missing but still mounted. Am I doing something wrong? I followed the instructions to the letter.
Want to use System SSD for MySQL DB.
