MySQL is an open-source Relational Database Management System (RDBMS), which is written in C and C++ languages and supports multiple platforms including Windows, Linux, macOS, UnixWare, etc. It is used by various applications for data storage, online publishing, and web apps. Also, it is supported by Oracle.
It works based on the client-server model with MySQL Server as the server. You can store, access, or retrieve the data stored in the server anytime.
In this blog, we discuss to get a brief introduction to one of the common MySQL error- MySQL is marked as crashed and should be repaired.
The MySQL error “MySQL is marked as crashed and should be repaired” may occur suddenly while you are accessing the MySQL. The frequency of the error is more after the forced shutdowns of MySQL Server. The other reasons could be the crash down of the MySQL Server, disk space shortage, hardware issues, power failures, etc. Whatever be the reason, you cannot access or use your MySQL tables anymore as it has been completely crashed.
If you are a professional or a common MySQL Server user, you must have taken backups of the MySQL Server database files. With a recent backup of MySQL Server, it would be quite easy to restore the whole database again. But If you do not have backups for MySQL Server data, then you will have to find some other solutions on your own, which would take both effort and time. So, our suggestion is to take periodic backups of the MySQL database.
Through myisamchk Tool
Users can find out the broken or crashed MySQL tables using the native tool provided by the MySQL application known as “myisamchk”.
Run this command on myisamchk command line.

Once you get to know the name of the tables that need repair, then you can execute the next command.
In the above command, you need to provide the table name which was found out in the first command (broken or crashed).
If the table is not repaired yet, you can try another command. Before that, just stop the web services, stop MySQLd and then run this command.
Next, restart the MySQLd and the web services and check if the error is fixed.
