Automatic input data download failed


New Member

I'm trying to verify my installation with the default case: ./create_newcase --machine=homebrew --case mycase --compset X --res f19_g16. I managed to get the setup and build to pass. However, the automatic download of the input_data fails; a manual download works but its just very tedious. The problem sounds similar to scripts_regression_tests failing during port to new local system due to error during inputdata download · Issue #3087 · ESMCI/cime.

Attached the output of ./check_input_data --download --debug

Any ideas would be highly appreciated.

With which protocol does manual download work? You can adjust the order that protocols are attempted by changing the order in config_inputdata.xml

Thanks for the quick reply.

I tried to change the order as suggested in the other thread. This didn't help. Manually, wget works (with the command string that is used in ./check_input_data), e.g.

lessig@einstein cesm-inputdata % wget --no-check-certificate --user anonymous --password user@example.edu ftp://ftp.cgd.ucar.edu/cesm/inputdata/cpl/gridmaps/gx1v6/map_gx1v6_TO_fv1.9x2.5_aave.130322.nc cpl/gridmaps/gx1v6

The problem apparently arose from having multiple servers in config_inputdata.xml. With only the ftp one in there it worked (I presume only svn or wget would work as well).

I was stepping through the code to locate the issue and it seems it arises from the merging of the checksum files in CESM/cime/scripts/lib/CIME/case/check_input_data.py:57-60 (on my Mac in any case).
