Even with brand new log files, I got the messages again:

InnoDB: Your database may be corrupt.
what do you think is the correct log sequence number? How much do you have data?
The pages have lsn about 16 GB or 24 GB, while the log files only have lsn about 8 GB.
Please send me your whole .err log. That may contain clues of what has happened.

.............. Heikki, many thanks for your reply.
I do well understand that I must *never* touch logfiles or datafiles, and I did not do that. The only thing I did was the following:
$ mysqladmin shutdown This was 4.0.14. The error log said: InnoDB: Starting shutdown... InnoDB: Shutdown completed /usr/sbin/mysqld: Shutdown Complete $ cp /usr/sbin/mysqld-4.0.15 /usr/sbin/mysqld This is bin/mysqld from "mysql-standard-4.0.15-pc-linux-i686.tar.gz" $ rcmysql start Now the error log said: 030923 15:10:12 mysqld started 030923 15:10:14 InnoDB: Error: page 45 log sequence number 6 193108436 InnoDB: is in the future!

Version: '4.0.15-standard-log' socket: '/var/lib/mysql/mysql.sock' port: 3306
Now I switched back to 4.0.14: $ mysqladmin shutdown $ cp /usr/sbin/mysqld-max /usr/sbin/mysqld This is the old 4.0.14 binary, compiled by MySQL AB. $ rcmysql start The error log said: 030923 15:10:46 InnoDB: Started /usr/sbin/mysqld: ready for connections. Version: '4.0.14-Max-log' socket: '/var/lib/mysql/mysql.sock' port: 3306
I had 4.0.14 running for quite some time now and neither experienced any problem nor saw anything in the error log.
The InnoDB part of my.cnf looks like this:
innodb_data_home_dir = innodb_data_file_path = /dev/raw/raw1:6149Mraw;/var/mysql/innodb/ibdata:100M:autoextend innodb_log_group_home_dir = /var/mysql/innodb.log innodb_log_arch_dir = /var/mysql/innodb.log
innodb_mirrored_log_groups = 1 innodb_log_files_in_group = 3 innodb_log_file_size = 100M innodb_log_buffer_size = 64M innodb_flush_log_at_trx_commit = 2 innodb_flush_method = O_DSYNC innodb_log_archive = 0 innodb_buffer_pool_size = 128M innodb_additional_mem_pool_size = 16M innodb_file_io_threads = 4 innodb_lock_wait_timeout = 50
Just ask if you need more information.
