How to Fix MySQL Error 1195 – SQLSTATE: HY000 (ER_CRASHED_ON_REPAIR) Table ‘%s’ is marked as crashed and last (automatic?) repair failed

MySQL is a popular open-source relational database management system used by many websites and applications. However, like any software, it can encounter errors and issues that need to be resolved. One common error that MySQL users may come across is Error 1195 – SQLSTATE: HY000 (ER_CRASHED_ON_REPAIR) Table ‘%s’ is marked as crashed and last (automatic?) repair failed. This error indicates that a table in the database has crashed and the automatic repair process has failed. In this article, we will explore the causes of this error and provide solutions to fix it.

Causes of MySQL Error 1195

There are several reasons why a MySQL table may become crashed and trigger Error 1195:

  • Hardware or software issues: Sudden power outages, hardware failures, or software bugs can cause a table to crash.
  • Inadequate disk space: If the disk space allocated for the database is full, it can lead to table crashes.
  • Corrupted table files: If the table files are corrupted due to disk errors or other issues, it can result in a crashed table.
  • Incompatible MySQL version: Using an incompatible MySQL version or upgrading without proper precautions can cause table crashes.

Fixing MySQL Error 1195

When encountering Error 1195, there are several steps you can take to fix the issue:

1. Check the table status

First, you need to check the status of the crashed table. You can do this by running the following command in the MySQL command-line interface:

SHOW TABLE STATUS LIKE 'table_name';

Replace ‘table_name’ with the name of the crashed table. Look for the ‘Engine’ column in the output. If it shows ‘MyISAM’ or ‘InnoDB’, proceed with the appropriate steps below.

2. Fixing a crashed MyISAM table

If the table is using the MyISAM storage engine, you can try repairing it using the REPAIR TABLE command. Run the following command:

REPAIR TABLE table_name;

Replace ‘table_name’ with the name of the crashed table. MySQL will attempt to repair the table and fix any corruption issues. If the repair process is successful, the table should be accessible again.

3. Fixing a crashed InnoDB table

If the table is using the InnoDB storage engine, you can try the following steps to fix the issue:

  1. Stop the MySQL server.
  2. Locate the InnoDB data directory, which is typically located at /var/lib/mysql/.
  3. Backup the entire directory or at least the files related to the crashed table.
  4. Delete the ibdata1 file and any ib_logfile* files in the InnoDB data directory.
  5. Start the MySQL server.
  6. Import the backed-up table files into the InnoDB data directory.

After following these steps, the InnoDB table should be repaired and accessible again.
