I'm trying to identify why, suddenly, 100% of our disk space is in use. I have already rebooted but the issue persists.
Here are the outputs of some commands that are showing some strange (for me) results:
danny@hydrogen:~$ df -h

The server is running Ubuntu 10.04.4 LTS.
System load: 2.85 Temperature: 8 C
Usage of /: 94.7% of 129.07GB Processes: 132
Memory usage: 39% Users logged in: 0
Swap usage: 0% IP address for eth0: 192.168.1.124
=> / is using 94.7% of 129.07GB
I'm struggling to comprehend why this is happening! Any pointers would be appreciated.
