When starting CAM, a NetCDF error occurred.

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.

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.

Yes, I used an updated version of the NetCDF library, and that issue was resolved. I created a new case with the default configuration being the same as before. However, when running the BSSP126 scenario, I encountered a new problem related to the MPI library. The error description is as follows. Do you have any suggestions for resolving this issue?

It's crashing because the ww3 model cannot write to the filesystem - confirm you have write permission in the output directory and that it is accessible from all compute nodes.
