If you are encounter the following error during login, it is an indication of your home directory being full. OnDemand relies on some space being available on the home directory to open and maintain per session logs. The solution for this is to clear up some space in the home directory. You can still login to the cluster via another terminal client (ssh) to review and clean/delete content from home directory. If you don't have or having difficulty with setting up a terminal client setup for ssh access, Contact our Support Team

No space left on device

This error indicates that your home drive is full. Your home directory quota needs to be under 20GB. You will probably see an image like this:

NeSI_OnDemand_No_Space_Left_1.png

To resolve this issue:

  1. Select Clusters -> NeSI HPC Shell Access

    NeSI_OnDemand_No_Space_Left_1.png

  2. Log in to your NeSI account through the terminal.

  3. Type into the terminal nn_storage_quota. This will show the amount of space in your home, project, and nobackup directories. You will see that your home directory is full.

    username@login03:~$ nn_storage_quota 
Quota_Location                          AvailableGiB           UsedGiB Use%
home_username                                     20                20  100

  4. Type into the terminal:

    cd
du -hs $(ls -A) | sort -hr

  5. The du -hs $(ls -A) | sort -hr command will list the size of the files and folders that your home directory contains, from biggest to smallest. You will need to move/remove files and folders off the home directory.

  6. Once you have space free in your home directory, try using your OnDemand Apps again.
