mysqld down

[bluebubblefly]

My mysqld server is down. Looking at mysqld.log I get the following message:

070627 9:18:07 [ERROR] /usr/libexec/mysqld: Error writing file '/var/run/mysqld/mysqld.pid' (Errcode: 28)
070627 9:18:07 [ERROR] Can't start server: can't create PID file: No space left on device

But there is no file at /var/run/mysqld, so how this can be full?

How can I restore MySQL service?

Problem solved. I just delete some files from /var/www/vhosts/... to free some space.
