**How severe does this issue affect your experience of using Ray?**

- Low: It contributes to significant difficulty to complete my task, but I can work around it.
  - (I need to know the answer to this question)

I’m receiving:

```auto
  File "python/ray/_raylet.pyx", line 908, in ray._raylet.spill_objects_handler
  File "python/ray/_raylet.pyx", line 911, in ray._raylet.spill_objects_handler
  File "/home/ray/anaconda3/lib/python3.8/site-packages/ray/_private/external_storage.py", line 657, in spill_objects
    return _external_storage.spill_objects(object_refs, owner_addresses)
  File "/home/ray/anaconda3/lib/python3.8/site-packages/ray/_private/external_storage.py", line 302, in spill_objects
    return self._write_multiple_objects(f, object_refs, owner_addresses, url)
  File "/home/ray/anaconda3/lib/python3.8/site-packages/ray/_private/external_storage.py", line 149, in _write_multiple_objects
    written_bytes = f.write(payload)
OSError: [Errno 28] No space left on device
An unexpected internal error occurred while the IO worker was spilling objects: [Errno 28] No space left on device

```

This makes sense. My dataset is somewhat large and it might be the case that some workers run out of disk space when `dataset.count()` is parallelized. Does Ray handle this case elegantly, or will this break things?
