How to Solve MySQL's '1114 (HY000): The table is full' Error?

Troubleshooting "1114 (HY000): The table is full" Error in MySQL

When attempting to insert a new row into a MySQL InnoDB table, an "1114 (HY000): The table is full" error may be encountered. This error occurs when the table has reached its maximum storage capacity.

Possible Causes:

1. Low innodb_data_file_path Size: The innodb_data_file_path parameter in the MySQL configuration sets the maximum size for all InnoDB tables combined. If this value is too low, all tables will reach their storage limit prematurely.
2. Limited Disk Space: Before addressing configuration issues, ensure that the available disk space is sufficient. If the disk space is exhausted, no new data can be added to the tables.

Resolution:

1. Increase innodb_data_file_path: Modify the my.cnf configuration file to allocate more storage space for InnoDB data. For example, increase the size to 1 GB:

innodb_data_file_path = ibdata1:1G:autoextend:max:2G

2. Enable innodb_file_per_table: Instead of allocating shared storage for all InnoDB tables, use innodb_file_per_table to create a separate data file for each table. This allows tables to grow independently without affecting each other's storage capacity.

innodb_file_per_table = 1

3. Check Disk Space: If the disk space is not sufficient, add more storage capacity to the server.
4. Restart MySQL: After making any configuration changes, restart MySQL for the changes to take effect.

Additional Notes:

• The error occurs only when adding new rows to the specific table that reached its maximum storage size.
• The specific table size can be checked using the SELECT COUNT(*) query on the table.
