According to MySQL 5.0 Certification Study Guide, Page 443,444 Section 30.4:

You can check InnoDB tables by using the CHECK TABLE command or using a client program to issue the statement for you. However, if an InnoDB table has problems, you cannot fix it by using REPAIR TABLE because that statement applies only to MyISAM.

If a table check inidicatesindicates that an InnoDB table has problems, you should be able to restore the table to a consistent state by dumping it with mysqldump, dropping it, and recreating it from that dump.

In the event of a crash of a MySQL Server or on the host on which it runs, some InnoDB tables might need repairs. Normally, it suffices simply to restart the server because the InnoDB storage engine performs auto-recovery as part of its startup sequence. In rare cases, the server might not start up due to the failure of InnoDB auto-recovery. If that happens, use the following procedure:

  • Restart the server with the --innodb_force_recovery option set to a value in the rage from 1 to 6. These values indicate increasing levels of caution in a avoiding a crash, and increasing levels of tolerance for possible inconsistency in the recovered tables. A good value to start with is 4.

  • When you start the server with --innodb_force_recovery set to a non-zero value, InnoDB treats the tablespace as read-only. Consequently, you shouyldshould dump the InnoDB tables with mysqldump and then drop them while the option is in effect. Then restart the server without the --innodb_force_recovery option. When the server comes up, recover the InnoDB tables from the dump files.

  • If the preceding steps fail, it's necessaarynecessary to restore the InnoDB tables from a previous backup.
