The disk quote exceeded may not be your home directory (which is what I assume has the 1 TB disk space you quote), but rather the temporary directory. You may want to get in touch with the HPC admin to see if you can set a different temp directory, and/or why you do not have enough space in your home directory (or whatever destination you set for your output artifact).
Probably because your disk space (or temp space) has filled up between then and now. Or are you able to successfully run 2018.11 now?
