When starting CAM, a NetCDF error occurred.

[CGL]

Hi, CESM team.

I am using CESM 2.1.3 and running the BSSP126 scenario. The setup command I used is:

./create_newcase --case /public/home/acsqu89hc3/apprepo/cesm/2.1.3-intelmpi2017/case/BSSP126_Origin_userLanduse --compset BSSP126 --res f09_g17 --machine sugon --run-unsupported

When submitting the case, I encountered the following error:

pio_support::pio_die:: myrank= -1 : ERROR: ionf_mod.F90: 235 : NetCDF: Attempt to use feature that was not turned on when netCDF was built.

I have attached the `cesm.log`, `cpl.log`, and `atm.log` files for reference.

Here are my attempts: Based on previous posts, I converted the file fy_0,9x1,25_nc3000_NSW042_NrS008_Co060_Fi001_ZR_sgh30_24km_GRNL_c170103.nc to the CDF5 format using the command nccopy -k cdf5, but the same error still occurred. I also tried different versions of the NetCDF library(env.sh), but the error persisted.

Just a thought: Are you certain that this is the only file that needed to be converted? Otherwise, I have no additional suggestions.

I identified the problematic file based on the error location in the cesm.log. However, I am unsure whether other files need to be converted as well, and I need a standard for comparison.

You may need to try to update your netcdf library.
