the app library for HDF5 has an issue with NFSv4.. it can be worked around, but our fear is that it shows up in another application the result is "I cant get a file lock" (this was tested on Ganesha) Articles. https://serverfault.com/questions/972623/parallel-mpi-file-open-failed-on... https://forum.hdfgroup.org/t/hdf5-files-on-nfs/3985/8 does this sound familiar to anyone?

Hi Malahal, Thank you for responding.. I'm not really looking for break/fix help (at this moment), but was wondering if anyone knows about the HDF5+Ganesha combination - and if there are any configs that could be applied. It's very possible we'll need to fix, but for right now, this is just an inquiry..
