Question

When I run:

$ python manage.py syncdb

I get the following output:

Creating table auth_permission
Traceback (most recent call last):

_mysql_exceptions.InternalError: (1, "Can't create/write to file '/usr/local/mysql/data/wzhere/auth_permission.MYI' (Errcode: 2)")

Any ideas on how to debug? I’ve given the database user all the permissions it should need. Not sure what MySQL is balking at here.

UPDATE: The problem here ended up being that I had installed MySQL multiple times (first 32-bit, then 64-bit when I realized I should be doing that) and although I followed some instructions on how to un-install MySQL, the instructions are slightly different for Snow Leopard. Once I actually did an uninstall and clean install, this problem went away.

Answer 1

The question was how to debug the problem and as already pointed out by Agos, Errno 2 is ‘No such file or directory’. You might want to look in the data directory of MySQL and check if the directory is actually there and has correct permissions

shell> cd /usr/local/mysql/data/
shell> ls -ld *
drwx------    17 geert   admin         578 Oct  1 19:33 someabstract

The above should give you list of directories (which are the MySQL databases) and their permissions. Check whether the ‘wzhere’ directory in particular..
It’s a bit weird error message you get I should say.

(Trying another Django DB back-end wouldn’t solve anything in this case.)
