Home File System Quotas

May 03, 2019

A gentle reminder that the Eagle /home directory of all HPC user accounts is limited to a size of 50GB. We are still implementing advanced space usage reporting features, so for the time being you can quantify your /home size by running du -hs ~ (which will take a minute or two to complete). The most common space-usage observed is due to large Anaconda virtual environments. Environments can be installed to /scratch and /project directories to avoid /home directory consumption. The Anaconda cache also stores many zipped python packages which can grow to be several GB–you can empty the cache by running conda clean --all and following the terminal prompts. Continue reading
