Hello all,
I am looking after the installation of web-based software built using
MySQL with mostly InnoDB tables. The software is currently installed in
over 10 locations and has been running continually for several months in
some of these. These installations vary from several thousand to several
hundred thousand lines in the database, with 100 tables.
Backups are made roughly daily from within the application, which uses
the php 'exec' function to directly call mysqldump.
One server had a problem while creating a backup last week. The routine
normally takes about 30 seconds, but in this case went on for over 30
minutes. During this, the application was responding correctly to other
users. After a reboot, InnoDB has been disabled, which left the data
inaccessible. The database was restored using the most recent backup,
but all tables are now using the MyISAM engine.
The server is running Windows Server 2003 and MySQL version
5.0.24a-community-nt installed using the xampp package.
The relevant sections of the MySQL log file are below, after which it
went into a near endless cycle of 'Incorrect information in file:' errors.
The errors are due to InnoDB being disabled. As far as I can tell, this
has happened as the InnoDB log file ib_logfile0 is the wrong size. This
took me to the description for adding and removing log files at:
http://dev.mysql.com/doc/refman/5.0/en/adding-and-removing.html
However, something has happened in this case to expand the file
id_logfile0 and instructions are not given on how to clean it out and
start again.
Any help on how to sort this out without a reinstall or, more
importantly, to understand why this may have happened, would be greatly
appreciated.
Best regards,
Andrew Simpson
