Failed to store event info

Production Risk

Low — the event will not be created; investigate storage.

What this means

ER_EVENT_STORE_FAILED (1545, SQLSTATE HY000) is raised when MySQL cannot persist event metadata to storage, typically due to I/O errors or schema issues.

Why it happens
  1. 1Disk I/O error writing to mysql.event table
  2. 2Insufficient disk space
  3. 3Corruption in the mysql schema
How to reproduce
trigger — this will error
trigger — this will error
CREATE EVENT my_event ON SCHEDULE EVERY 1 HOUR DO SELECT 1;
-- Fails if storage error occurs

expected output

ERROR 1545 (HY000): Failed to store event 'my_event' into mysql.event

Fix

Check mysql.event table and disk space

Check mysql.event table and disk space
CHECK TABLE mysql.event;
REPAIR TABLE mysql.event;

-- Check disk space and retry:
CREATE EVENT my_event ON SCHEDULE EVERY 1 HOUR DO SELECT 1;

Why this works

Repairing the event table or addressing disk space resolves storage failures.
