You run out of disk space in your Jupyter notebook which disallows you from starting the notebook cloud environment. When you try to start the cloud environment, it appears to be starting up as usual, but never fully starts up and eventually stops.
How to fix
To resolve the issue, you will need to delete data from the cloud environment. To do so, you will first need to regain the ability to start the cloud environment by adjusting the hard disk space in the cloud environment configuration page.
NOTE: You will not be able to reduce the size afterwards. If you want to use a lower disk size to reduce costs, you will need to generate a new cloud environment runtime after deleting the files.
First, make sure you've selected Custom for the Profile.
Then increase the Disk size (GB) and click "Next" and then "Update" on the subsequent screen:
You should no longer have issues accessing your notebook cloud environment due to inadequate space. At this point you should be able to delete files and continue working.
If you delete files and still run into this issue, or if you increase the disk size and you are still unable to start the cloud environment, something else may be going on. Please contact us using one of the methods described here and we'll be happy to take a look!
