No space left on device

Dear All
I have installed openMolcas on a cluster but when I run calculations with smaller basis functions(aug-cc-pvdz) it works nicely but when I use basis function of high quality(aug-cc-pvtz) it gives following message.

"Traceback (most recent call last):
  File "/opt/sw/molcas/sbin/pymolcas", line 483, in <module>
    sys.exit(main(os.path.realpath(f)))
  File "<string>", line 214, in main
  File "<string>", line 685, in auto

    copyfile(src, dst, follow_symlinks=follow_symlinks)
  File "/opt/sw/python/3.6.3/lib/python3.6/shutil.py", line 122, in copyfile
    copyfileobj(fsrc, fdst)
OSError: [Errno 28] No space left on device"

----------------------------------------------------------------------------------------
What is the possibility of this error or how we can remove this error? Is this due to installation issues? Can anyone suggest a proper guideline for OpenMOLCAS installation (perfect) on cluster. As I myself do not have an experience of such issues and also our IT specialist do not have much knowledge about MOLCAS environment.It will be really great help if someone can suggest a detail of how to properly install OpenMolcas with all requirements (memory & other required).

Thank you very much

Re: No space left on device

The error is pretty clear: OSError: [Errno 28] No space left on device A larger basis set uses more disk space. You can use RICD, if you aren't using it already, to reduce disk usage. Also make sure that the scratch directory (WorkDir) is in a local disk to the node, with plenty of space.
