Log files
In order for MySQL Replication to function properly you need to check log files in /var/lib/mysql
Open master-log-bin.index, it should contain names of the files which really exist in same folder. If there's some mismatch - edit this file: enter missing names for files or delete file names which does not represent real files in this folder.
Same with file slave-relay-log.index
