If you see the error message: “Disk quota exceeded @ dir_s_mkdir – /home/username/…”. It means your home directory has hit the quota limit. No fear, this happens with regular use of the HPC environment. You will need to remove some items in your /home directory. Run this command in the terminal (with your own username) to see which items take up the most space: du -h —max-depth=1 /home/username”
