Carina Troubleshooting
Connection & Startup Issues
It's frustrating when you can't connect! Here are a few things to check:
Are you on the Full-Tunnel Stanford VPN?
This is a common issue! Confirm that you are connected to the Stanford VPN using the full tunnel. Stanford UIT supports the VPN and provides documentation.
Do you have space in your $HOME?
Running out of disk space will disrupt your work.
A lack of free disk space can cause Jupyter and its apps to fail to connect, freeze up, or otherwise behave oddly. The error messages may not tell you that disk space is the issue, but it is the most likely cause.
The good news is, you can solve the problem on your own. Your account will still allow you to connect via SSH when you are over your disk quota. From there, you can see your disk usage.
The command to check your usage is: du -hs $HOME
It will return something like: 5GB /home/<sunetid>, which means:
| 5GB | /home/<sunetid> |
|---|---|
| Shows how much disk space you are currently using. Your $HOME quota is 25GB, and you should keep a few GB free for your applications to use. | Shows your $HOME path |
If you are over your quota, move or delete files via the command line in your terminal to free up space.
Slurm.conf error in JupyterLab
If you open the terminal in JupyterLab at onprem.carina.stanford.edu and enter a Slurm command, you will receive an error. The terminal in JupyterLab is specific to that notebook, and does not connect with the wider environment. It will look something like this:
Slurm commands can only be used in an SSH terminal connection. Follow the linked directions to connect.
