Re-running the pipeline atop of an existing folder

Issue: OSError: [Errno 28] No space left on device occurs on third step of the pipeline

Steps to reproduce: restart the pipeline with the same target name for output folder as in a previous run

It appears that re-running the pipeline without renaming/deleting output folder results in an error. I think either the folder should be checked before the pipeline starts or be it considered as default behaviour to erase previous job, but not fail in the middle of the pipeline.
