Cpanel Problem

Today I've trying to login into cpanel but I've got a notice something like this,

"Sorry for the inconvenience!
The filesystem mounted at / on this server is running out of disk space. cPanel operations have been temporarily suspended to prevent something bad from happening. Please ask your system admin to remove any files not in use on that partition."

What happen?
