MySQL Cannot Find InnoDB Tables After Restart + InnoDB Tablespace Missing + InnoDB: a New Database to be Created

(Doc ID 1333177.1)

Last updated on OCTOBER 16, 2017

Applies to:

MySQL Server - Version 4.0 and later
Information in this document applies to any platform.


On a Linux/Unix platform after restarting MySQL, InnoDB fails to find any of the tables, everything was working before the restart, and the error log contains an error like:

InnoDB: The first specified data file /var/lib/mysql/ibdata1 did not exist:
InnoDB: a new database to be created!
110627 10:00:00 InnoDB: Setting file /var/lib/mysql/ibdata1 size to 10 MB
InnoDB: Database physically writes the file full: wait...

If innodb_file_per_table is used, the *.idb files for the tables are still there.

Another symptom can be that the ibdata1 file is missing from the latest backups, although this might not necessarily be the case.
