Corrupt InnoDB tables after every mysql restart. What's wrong?
markus you want to read the very last paragraph on mysql.com docs for resizing log file http://dev.mysql.com/doc/refman/5.1/en/innodb-data-log-reconfiguration.html - you only need to remove the ib_ log files and not the ibdata1 file


  Stop the MySQL server and make sure that it shuts down without errors
  (to ensure that there is no information for outstanding transactions
  in the log). Copy the old log files into a safe place in case
  something went wrong during the shutdown and you need them to recover
  the tablespace. Delete the old log files from the log file directory,
  edit my.cnf to change the log file configuration, and start the MySQL
  server again. mysqld sees that no InnoDB log files exist at startup
  and creates new ones.
