We are running MySQL version 5.0.45 on a Linux machine. Most of our tables are MyIASM but
we have recently installed drupal 7 and drupal 7 requires INNODB tables. Every now and
then when we restart MySQL using the commands /etc/init.d/mysql stop and /etc/init.d/mysql
start our sites that were built in drupal 7 do not come up. After much trial and error we
came up with the following solution:
We stop mysql
We remove the files ib_logfile0 and ib_logfile1
We rename ibdata1 to ibdata1.old (mv ibdata1 ibdata1.old)
We copy ibdata1.old back to ibdata1 (cp -a ibdata1.old ibdata1)
We start mysql
And everything is fine and the sites that use INNODB tables are fine.
We clearly have a problem but we have no idea where to start looking. If anyone has any
suggestions, we will be happy to hear them.
Thanks for any help.
