Had a question from a student:
He is trying to increase the innodb log file size by altering his .ini file.
After he makes the changes to the .ini file, he attempts to restart the server but fails.
Error messages indicate:
-ib_logfile0 has a different size
-can’t initialize database
The solution was posted by Jay Pipes in the MySQL forum (http://forums.mysql.com/read.php?22,32004,32014#msg-32014). Essentially MySQL tries to look for the log file that had the original size, doesn’t find it, aborts the restart.
Solution is to rename the log files. MySQL will recreate the appropriate log files with the appropriate sizes.
