MySQLERRORCommonHIGH confidence
InnoDB cannot write page to data file
Production Risk
Critical — Write failures can result in partial transactions and data corruption.
Why it happens
- 1Disk is full or the quota for the MySQL data directory has been exceeded.
- 2The data file has been made read-only by the operating system.
- 3Hardware failure on the storage device prevented the write.
Fix 1
Check available disk space
Why this works
Run df -h on the data directory to confirm there is sufficient free space.
Fix 2
Verify data file permissions
Why this works
Ensure the mysql user has write access to the InnoDB data files.
