Problems with the drop library in MySQL

Recently drop database pai; Error

Error 1010 (HY000): Error dropping database (can ' t rmdir './pai ', errno:39)

I just want to remove the library file and try it, so

Rm-rf/usr/local/mysql/data/pai

then I show databases;

And then there's the PAI library.

So drop database pai;

Error 1010 (HY000): Error dropping database (can ' t rmdir './pai ', errno:39)

Tangled for a long time, most of the online is not deleted Pai, but the inside of the file. I've deleted the library.

So mysql> show variables like '%datadir% ';

+---------------+-----------------+
| variable_name | Value |
+---------------+-----------------+
| DataDir | /var/lib/mysql/|
+---------------+-----------------+

We found Pai in this directory.

So Rm-rf/var/lib/mysql/pai

then show databases;

The result is gone and is deleted.
