You can use the command (there must be ample space for the mysql files)
REPAIR TABLE `
for repairing individual tables

Connect to your server via SSH
then connect to your mysql console
REPAIR TABLE TABLE;
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

This means your MySQL table is corrupted and you need to repair it. Use
myisamchk -r /DB_NAME/wp_posts
from the command line. While you running the repair you should shut down your website temporarily so that no new connections are attempted to your database while its being repaired.

I had issues with my general log on my dev server. I was able to run the following in the mysql cli to fix the issue.
truncate table general_log;
Note, this will delete all the contents of the table.
