Why do I receive “no space left” error when writing data to my home directory?
If you receive the error “No space left on device” when you try to write data to your home directory, it indicates the disk is full. First, check your home directory quota. Each user has 500 GB quota of storage and the quota information is shown when you login to our systems. If your disk quota is full, consider reducing your disk space usage. If your disk quota isn’t full (usage less than 500GB), it is very likely that your disk is filled up with ‘snapshot’ files, which are invisible to users and used to track fine-grained changes to your files for recovering lost/deleted files. In this case, please contact OSC Help for further assitance. To avoid this situation in future, consider running jobs that do a lot of disk I/O in the temporary filesystem ($TMPDIR or $PFSDIR) and copy the final output back at the end of the run. See Available File Systems for more information.
