MySQL 1204: Cannot update entry.

  1. Check the server's disk space:


df -h

  1. Check the MySQL error log for more details:


grep '1204' /var/log/mysql/error.log

  1. Verify the table's storage engine, focusing on InnoDB status:


SHOW TABLE STATUS LIKE 'yourtablename';

  1. For InnoDB, check if you've hit the `innodbdatafile_path` limit:


SHOW VARIABLES LIKE 'innodbdatafile_path';

  1. Inspect the database and table sizes:


SELECT tableschema AS `Database`, tablename AS `Table`, round(((datalength + indexlength) / 1024 / 1024), 2) `Size in MB` FROM informationschema.TABLES ORDER BY (datalength + index_length) DESC;

  1. If using InnoDB, check the InnoDB storage usage and limits:


SELECT variablename, variablevalue FROM informationschema.globalstatus WHERE variablename IN ('Innodbdatawritten', 'Innodbdata_read');

  1. Increase the database/table size limit if the error is due to a size limit being reached, for instance, by adjusting the `innodbdatafile_path` for InnoDB:


SET GLOBAL innodbdatafile_path = 'ibdata1:12M:autoextend';
Note: Adjust the size (`12M`) according to your requirements.

  1. Finally, if applicable, consider purging unnecessary data or archiving old data to free up space.
