MYSQL Table is marked as crashed - HOWTO

Today I found a:

"mysqldump: Got error: 145: Table is marked as crashed and should be repaired when using LOCK TABLES"

Just do this:


1.-Log into Mysql:

[root@webapp html]# mysql -uroot -p

2.-Change to DB with the issue:

mysql> use LiveDB;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed

3.-Check and repair:

mysql> check table bad_table;
