[error] Fatal Error: Can't Open And Lock Privilege Tables: Table 'mysql.host' Doesn't Exist
Error: log file ./ib_logfile0 is of different size up vote 74 down vote favorite 21 I just added the following lines in /etc/mysql/my.cnf after I converted one database to use InnoDB engine. innodb_buffer_pool_size = 2560M innodb_log_file_size = 256M innodb_log_buffer_size = 8M innodb_flush_log_at_trx_commit = 2 innodb_thread_concurrency = 16 innodb_flush_method = O_DIRECT But it raise "ERROR 2013 (HY000) at line 2: Lost connection to MySQL server during query" error restarting mysqld.

Change Innodb Log File Size
error log shows the following InnoDB: Error: log file ./ib_logfile0 is of different size 0 5242880 bytes InnoDB: than specified in the .cnf file 0 268435456 bytes! 100118 20:52:52 [ERROR] Plugin 'InnoDB' init function returned error. 100118 20:52:52 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed. 100118 20:52:52 [ERROR] Unknown/unsupported table type: InnoDB 100118 20:52:52 [ERROR] Aborting So I commented out this line # innodb_log_file_size = 256M And it restarted mysql successfully. I wonder what's the "5242880 bytes of log file" showed in mysql error? It's the first database on InnoDB engine on this server so when and where is that log file created? In this case, how can I enable innodb_log_file_size directive in my.cnf? EDIT I tried to delete /var/lib/mysql/ib_logfile0 and restart mysqld but it still failed. It now shows the following in error log. 100118 21:27:11 InnoDB: Log file ./ib_logfile0 did not exist: new to be created InnoDB: Setting log file ./ib_logfile0 size to 256 MB InnoDB: Database physically writes the file full: wait...

might be fine for a lot of servers but should you want to resize it, it is mysql innodb log file size not simply a case of changing innodb_log_file_size to the new size and restarting MySQL. MySQL will not start and produce error log output similar to the following: 140610 http://serverfault.com/questions/104014/innodb-error-log-file-ib-logfile0-is-of-different-size 20:09:14 InnoDB: The InnoDB memory heap is disabled 140610 20:09:14 InnoDB: Mutexes and rw_locks use GCC atomic builtins 140610 20:09:14 InnoDB: Compressed tables use zlib 1.2.3.4 140610 20:09:14 InnoDB: Initializing buffer pool, size = 128.0M 140610 20:09:14 InnoDB: Completed initialization of buffer pool InnoDB: Error: log file ./ib_logfile0 is of different size 0 http://dbadiaries.com/how-to-resize-mysql-innodb-log-files-without-errors 5242880 bytes InnoDB: than specified in the .cnf file 0 67108864 bytes! 140610 20:09:14 [ERROR] Plugin 'InnoDB' init function returned error. 140610 20:09:14 [ERROR] Plugin 'InnoDB' registration as a STORAGE ENGINE failed. 140610 20:09:14 [ERROR] Unknown/unsupported storage engine: InnoDB 140610 20:09:14 [ERROR] Aborting 140610 20:09:14 [Note] /usr/sbin/mysqld: Shutdown complete MySQL will not start because the configured value in my.cnf is not the same as the current log file size. How to safely adjust Innodb log file size (Example demonstrated on a Ubuntu 12.04LTS instance) 1/ Make sure that innodb_fast_shutdown is NOT configured as 2 You may suffer data loss if this is the case. Change to either 0 or 1. Setting as 0 will take longer to shutdown the server so 1 is preferred. Check out more information on this at this link SHOW VARIABLES LIKE 'innodb_fast_shutdown' Change to 1 to perform a fast shutdown SET GLOBAL innodb_fast_shutdown=1; 2/ Safely stop the MySQL service checki

Comments (2) Related Posts #1 written by Eric 4 years ago I have installed mysql-5.5.24-osx10.6-x36.pkg MySQLStartupItem.pkg on OSX 10.6.8. I have not created any my.cnf, because I want the defaults used. Yet I am getting error: InnoDB: Error: log file ./ib_logfile0 is of different size 0 268435456 bytes InnoDB: than specified in the .cnf innodb log file file 0 5242880 bytes! Any suggestions would be appreciated. -Eric Quote #2 written by Mike Purcell 4 years ago @Eric: I've run into this situation before, if you follow the guidelines outlined here you should be able to start your mysql service. The only change I would make is that instead of deleting the files, just move them into a temp (/tmp) directory in case you need to revert the change.

This is what I do: Stop MySQL Edit my.cnf (changing innodb_log_file_size) Remove ib_logfile0/1 Start MySQL Starts fine however all InnoDB tables have the .frm file is invalid error, the status shows InnoDB engine is disabled so I obviously go back, remove the change and everything works again. I was able to change every other variable I've tried but I can't seem to find out why InnoDB fails to start even after removing the log files. Am I missing something? Thanks. Edit: Pasting of the log below - looks like it still seems to find the log file even though they are not there?
