Table is marked as crashed and should be repaired

I am getting this error in wordpress phpMyadmin

#145 - Table './DB_NAME/wp_posts' is marked as crashed and should be repaired 

When I login to phpMyadmin, it says wp_posts is "in use"

My website is currently down because of this.

I googled this problem, but I don't see the "repair" button on phpMyadmin. Please let me know how to fix this. I am not sure where to issue PHP command. Please advise, my proficiency with PHP is very basic.

Solution 1:

Here is where the repair button is:

Solution 2:

Run this from your server's command line:

 mysqlcheck --repair --all-databases

Solution 3:

I had the same issue when my server free disk space available was 0

You can use the command (there must be ample space for the mysql files)

REPAIR TABLE `<table name>`;

for repairing individual tables

Solution 4:

Connect to your server via SSH

then connect to your mysql console

and

USE user_base
REPAIR TABLE TABLE;

-OR-

If there are a lot of broken tables in current database:

mysqlcheck -uUSER -pPASSWORD  --repair --extended user_base

If there are a lot of broken tables in a lot of databases:

mysqlcheck -uUSER -pPASSWORD  --repair --extended -A
