Updated vsphere 5 to 5.1. The upgraded to Ubuntu server 12.04 from 11.10. Ubuntu was working just fine. One week later, then VMware vsphere tech helped us install the vmware tools 5.1 - now reading disk is full - but it is not. sudo apt-get clean does nothing. Removing files does nothing. The Ubuntu server is unusable - disk usage analyzer stats are impossible. Has anyone else had this problem?
