The filesystem mounted at / on this server is running out of disk space. Any solution

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.

I have this error upon trying to login to the cPanel @ chopin.x10hosting.com. Last night, I seen this error then then in a moment later around 10 minutes. Then this day, I have still the same error.. Any solution or why it did happen?

It appears all users on the server 'Chopin' are experiencing this problem when trying to access cPanel. This is out of your control and you will need to wait for an administrator to fix this problem - this is not related to your individual disk space because of course it is unmetered.

As a side-effect it also appears MySQL is offline.
