I have an own partition for mysql-datadir with EXT4. There exists the lost+found directory.
If i use mysqlcheck i get:

mysqlcheck: Error: Couldn't get table list for database #mysql50#lost+found: Can't read dir of './lost+found/' (errno: 13 "Permission denied")

If i add to my.cnf

ignore-db-dirs = lost+found

and restart database server everything seems to be fine.
But if i try to use mysqlcheck again now i get

mysqlcheck: unknown variable 'ignore-db-dirs=lost+found'
