MySQL 1195: Table is corrupted.

What is MySQL 1195: Table is corrupted.

Immediately stop any further write operations to the affected table to prevent further corruption.

Take a backup of the affected table and the entire database, if possible, using the `mysqldump` command:

mysqldump -u username -p databasename > backupdatabase_name.sql mysqldump -u username -p databasename tablename > backuptablename.sql

Check the integrity of the table using the `CHECK TABLE` command:

CHECK TABLE table_name;

Attempt to repair the table using the `REPAIR TABLE` command:

REPAIR TABLE table_name;

If the `REPAIR TABLE` command does not fix the issue, and the table uses the MyISAM storage engine, use the `myisamchk` utility:

myisamchk --recover /path/to/data/dir/table_name.MYI Note: Replace `/path/to/data/dir/` with the actual path to your MySQL data directory.

If the table uses the InnoDB storage engine and cannot be repaired using `REPAIR TABLE`, you may need to restore the table from a backup. Before doing so, you can try to force InnoDB recovery by editing the `my.cnf` or `my.ini` file under the `[mysqld]` section:

innodbforcerecovery = 1 Note: Start with `1` and gradually increase to `6`. Be cautious as higher levels can cause permanent data loss. After setting this, restart the MySQL server.

After recovery efforts, verify the integrity of the table again using the `CHECK TABLE` command.

Finally, monitor MySQL logs for any errors or warnings that could indicate underlying problems that led to the corruption:

tail -f /var/log/mysql/error.log Note: Adjust the log file path based on your MySQL configuration.
