HOW TO FIX A CORRUPTED TABLE IN A MYSQL DATABASE -Business Legions Blog

One of the websites I manage Digital Signage Blog was not displaying correctly (posts were not displaying, menu was missing links to the categories and only displaying pages) and after some investigation, I discovered one of the database tables (the categories table – wp_term_taxonomy) was corrupted. I attempted to repair the database by using these instructions How to check and repair MySQL tables using MySQLcheck and How to repair WordPress databases but both instructions didn’t work.

When I ran the repairs using the above methods there were no errors being reported that the database was corrupted. The only way I figured out that one of the tables was actually corrupted was to login to phpMyAdmin and saw the status of the table being in use.

When I tried repairing that particular table using phpMyAdmin and it reported ‘Can’t create new tempfile:..’ and the ‘Operation failed’

So to fix this I had to login to my VPS and use the SSH terminal to issue the following commands. Firstly go to the database files

cd /var/lib/mysql/[name_of_your_database]

1	cd /var/lib/mysql/[name_of_your_database]

Then use this command to fix it:

myisamchk -r -f wp-term_taxonomy.MYI

1	myisamchk -r -f wp-term_taxonomy.MYI

This was the result, it fixed 3 indexes.

myisamchk repair
