- Immediately stop writing to the affected partition to prevent data corruption.
- Backup your database if possible:
mysqldump -u username -p database_name > backup.sql
- Check the integrity of the partition and table with the CHECK TABLE command:
CHECK TABLE your
table
name;
- Attempt to repair the partition with the REPAIR TABLE command:
REPAIR TABLE your
table
name;
- If the partition is part of a larger table, consider running an OPTIMIZE TABLE command to reorganize the table and update index statistics:
OPTIMIZE TABLE your
table
name;
6. After repair, validate the table's integrity again with CHECK TABLE.
