How do you drop a corrupted INNODB database in MariaDB?
This may not work for everyone, but it did work for us on several occasions:


Stop the database (service mysql stop) 
edit mysql.cnf so that under [mysqld] section it has the:

[mysqld] 
innodb_force_recovery = 1 

Start the database (service mysql start) and in the logfile
you will see it force loading the bad database/table 
log into the
database server as root:  mysql -u root 
run the command "show databases[ENTER]" to get a list of database 
run he command "drop [dbname][ENTER]" where [thedb] is the database you need to drop. It will drop it but will complain that it cannot delete the directory ./[thedb]. 
Open a separate shell and go into /var/lib/mysql/[thedb]/ and remove the file(s) there. 
Stop the database (service mysql stop) 
Turn off the REPAIR mode by commenting out the line in
mysql.cnf 

[mysqld]
#innodb_force_recovery = 1 

restart the database with the command:  

service mysql start[ENTER]



Voila.

Now recreate the database and restore from your backup.

Thanks,
