/usr partition 100% full in Control Panel.
The /usr partition on this server is running out of disk space. WHM operation has been temporarily suspended to prevent something bad from happening. Please ask your system admin to remove any files not in use on that partition.
You can check the size of error_logs and access_logs on your Linux server and in case these files are large you can empty them by using following commands –
#cd /usr/local/apache/logs
#ls -sh error_logs
#ls -sh access_logs
The log files will generally be in the size of GB’s
#echo > error_logs
#echo > access_logs
This should resolve the issue.

Mysql gives error of access denied for root@localhost on cPanel Servers
The most possible cause of this error is an incorrect password. You can usually find the correct password in this file: /root/.my.cnf.
The file will contain the first root password the server was given once cPanel is installed. If it still does not work, you will need to reset the mysqld root password. To do so you can follow the below steps:
1. Stop mysqld – /etc/rc.d/init.d/mysql stop
2. Stop chkservd to keep it from interfering with mysqld –/etc/rc.d/init.d/chkservd stop
3. Start mysqld without the grant tables – mysqld –skip-grant-tables -u mysql &
4. Now change the pass.
mysql -u root mysql UPDATE user SET Password=PASSWORD(‘new_password’) WHERE user=’root’; FLUSH PRIVILEGES;
Now you just killall -9 mysqld and start it up normally with it’s safe_mysqld script.
