Why Is My InnoDB Table Reporting 'Full' (Error 1114) Even Though It Doesn't Seem Full?

InnoDB Table Full (Error 1114)

When attempting to add a row to an InnoDB table, you may encounter the error "1114 (HY000): The table [table name] is full." This issue arises despite the table not appearing to be at capacity.

One potential cause is a limited maximum size for the innodb_data_file_path in the my.cnf configuration file. In a typical configuration, the innodb_data_file_path may be set as follows:

innodb_data_file_path = ibdata1:10M:autoextend:max:512M

In this example, the total data size for all InnoDB tables combined cannot exceed 512MB. To resolve this issue, increase the max value to accommodate the required data size.

Alternatively, you can opt for an innodb-per-table scheme using innodb_file_per_table. This approach allocates a separate file for each InnoDB table, providing greater flexibility in terms of file size limitations.
