Ib_logfile0 Delete
works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the top InnoDB: 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 set global innodb_fast_shutdown = 0 = 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. And mysql 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 t

If I put it back to 512M mysql starts fine. How can I solve this?

And I increased it from the default value to 256 MB. As usual I got the error saying InnoDB: Error: log file ./ib_logfile0 is of different size 0 5242880 bytes. So error log file I moved these files to different location and restarted the MySQL server. It worked. Before shutting down the MySQL, server I also made innodb_fast_shutdown = 0. But I have a doubt, after MySQL shutdown can we expect mysql is an consistent state and all the data that were in the ib_logfile0 and ib_logfile1 have been written to data files. So that I can delete these files or should I do something else also. And if the answer is MySQL will be in consistent state than why these files contain some data even after graceful shutdown and start up with innodb_fast_shutdown = 0. [EDIT details] giving the steps i have done Steps i followed: SET GLOBAL innodb_fast_shutdown = 0 /etc/init.d/mysqld stop rm -f /var/lib/mysql/ib_logfile0 rm -f /var/lib/mysql/ib_logfile1 /etc/init.d/mysqld start Is the above step is fine? if yes then how come after the clean shutdown and start up the log files contains some data. Ideally it should be empty. mysql innodb mysql-5.5 database-administration share|improve this question edited Aug 27 '13 at 5:21 asked May 5 '13 at 13:28 Trying 14316 add a comment| 3 Answers 3 active oldest votes up vote 4 down vote accepted How are you coming to the conclusion that "these files contain some data even
there actually keep me investigating … something I've been missing for some time. Today Artemio Stenio posted a MySQL issue he encountered. The screenshot he shared could not provide much information, so I asked him to send the mysqld-upgrade-run.log instead. See an extract of the log: 130518 15:24:57 mysqld_safe mysqld from pid file /var/tmp/mysql-protected.lsPXtR/mysqld.pid ended 130518 15:29:39 mysqld_safe Starting mysqld daemon with databases from /var/lib/mysql 130518 15:29:39 InnoDB: The InnoDB memory heap is disabled 130518 15:29:39 InnoDB: Mutexes and rw_locks use GCC atomic builtins 130518 15:29:39 InnoDB: Compressed tables use zlib 1.2.7 130518 15:29:39 InnoDB: Initializing buffer pool, size = 128.0M 130518 15:29:39 InnoDB: Completed initialization of buffer pool InnoDB: Error: log file ./ib_logfile0 is of different size 0 50331648 bytes InnoDB: than specified in the .cnf file 0 5242880 bytes! 130518 15:29:39 [ERROR] Plugin ‘InnoDB' init function returned error. 130518 15:29:39 [ERROR] Plugin ‘InnoDB' registration as a STORAGE ENGINE failed. 130518 15:29:39 [ERROR] Unknown/unsupported storage engine: InnoDB 130518 15:29:39 [ERROR] Aborting130518 15:29:40 [Note] /usr/sbin/mysqld: Shutdown complete 130518 15:29:40 mysqld_safe mysqld from pid file /var/tmp/mysql-protected.wFdcx4/mysqld.pid ended Now, from the above errors we can see MySQL isn't starting because of conflicting "innodb_log_file_size". To fix the same we can either: 1. edit the value in my.cnf and match it with the size obtained in the log, or … 2. we can delete the ib_logfiles from the "datadir" and start MySQL. When the latter starts it re-creates the ib_logfile with the correct size if it is not present.
