I did the usually bzimage and bzroot replacement upgrade to go from rc16c to final 5.0 and everything went smoothly and I brought the array back online and I can access all my shares, but now mysql which is installed on the cache drive isn't working. I can go to the cache drive and see that the mysql folder is still there along with my databases and I went to unmenu and it's showing that mysql is set up re-install upon reboot, but xbmc isn't detecting the databases when I load it. Any suggestions?
