Please back up these data files until this bug has been closed, so that we can debug this problem. It should be repeatable on those data files. After that, the database is ready for connections, but InnoDB will still have to roll back incomplete transactions (which were active at the time of the previous crash). Marko MГ¤kelГ¤ It looks like InnoDB successfully applied the redo log, that is, restored the unwritten changes to all data files. The original (corrupted) files are still available. With this value the recovery apparently ran through and MySQL started as it should, however, none of the tables in the database were usable (mysql hinted me to repair them, just to tell me afterwards that REPAIR TABLE is not supported for innodb).ДЄfter a lot of struggeling we've physically removed the ibdata* and ib_logfile* files and table definitions and imported an old dump. Since MySQL could not be started at all and being not a MySQL expert per se when it comes to crash recovery, I looked for a way to skip the recovery / replay of these missing data and only found the 'innodb_force_recovery' variable which I set to 4. We initially thought that these binaries there were the cause for the misbehaviour and rolled back to the Debian 4.0 default binaries (5.0.32), which showed the same behaviour. The original crash occured with 5.0.67 with the kind-of unsupported mysql builds for debian-based machines from.

Mysql crashed for us tonight and a couple of data needed to be replayed (innodb).
