When connecting to the CADE machines with NoMachine, the most common error a user may receive is “Disk Quota Exceeded”. This message occurs when a user has used up the allotted space in their home directory (currently 8GB).
To fix this, you’ll need to grab an SSH session to a lab machine and delete some data that way.
Using Windows Powershell or a Mac Terminal, run “ssh username@lab1-1.eng.utah.edu”
Then run “du -xhad1 | sort -hr | head -n 20”
This will summarize your disk usage with depth=1. This will take a few minutes. Be patient!
For example:
[user@lab1-1 ~]$ du -xhad1 ~ | sort -hr | head -n 10
8.0G /home/user
6.7G /home/user/Downloads
507M /home/user/cs4200
234M /home/user/eclipse-workspace
95M /home/user/.mozilla
81M /home/user/.eclipse
64M /home/user/.nx
41M /home/user/PycharmProjects
22M /home/user/Videos
19M /home/user/Pictures
Here we can see that we’re using 8.0GB of space total. That’s our entire quota. Of the 8.0G, 6.7G is from the Downloads directory.
Let’s see what’s using the space in our Downloads directory.
[user@lab1-1 ~]$ du -xhad1 ~/Downloads | sort -hr | head -n 10
4.2G /home/user/Downloads/dataset.zip
2.4G /home/user/Downloads/DogVideo.mp4
12M /home/user/Downloads/Never Gonna Give You Up.mp3
Ah! that dataset we downloaded last semester is still in our Downloads directory. Let’s delete it.
[user@lab1-1 ~]$ rm /home/user/Downloads/dataset.zip
If you need to delete a directory (and all contents within), add the recursive and force options.
[user@lab1-1 ~]$ rm -rf /home/user/cs4200
You may also need to purge your NoMachine cache, as it may have gotten corrupted if NoMachine ran out of space while running.
[user@lab1-1 ~]$ rm -rf /home/user/.nx
