The error is telling you that you have attempted to write the file; but, in
the process you exceeded your disk quota (the space you are allowed to use)
and the operating system would not permit you to finish the file.

The problem is that you are attempting to use more disk space then you are
permitted to use on your account (at least for the selected filesystem).
Possible solutions are to save the data somewhere else where you have a
greater quota, delete some other files from your account to make room for
the new file, or talk to whoever administrates the systems and see if they
will add enough space to your quota to permit you to write this large file.
