One of MySQL’s default storage engines, InnoDB, is thought to have several sophisticated features built in, such as compliant transactions and foreign keys that support the ACID (Atomicity, Consistency, Isolation, and Durability) attributes. Mysql repair InnoDB is necessary when InnoDB databases become corrupt due to various reasons such as virus attacks, kernel-related bugs, unexpected power outages, MySQL faults, or related ones that result in Innodb assertion failure in thread MySQL error, preventing us from accessing the MySQL tables.

Some of the possible causes include Misconfigured Libraries, Hardware Faults, or Damaged/Corrupted Databases. Let’s look the steps to fix it:

1. Verify that every library is set up correctly, and if necessary, reinstall them right away.

2. Try to fix any hardware problems right away if there are any. We can find the entries related to hardware issues by looking through the system, application, or MySQL error logs.
