After upgrading to RH7 (from RH6.2) I get and ERROR 1008: Can't drop database 'dvd'. Database doesn't exist. when I try to drop it.

When I do a show databases; it does list it. Also when I do a use dvd; I get Can't read dir of ./dvd/ (errorcode:13) but then it does change and I can see the tables.

Any suggestions?
