<p class="MsoNormal"><span lang="EN-US">The original error message (before working around the HDF5 driver) has been that permissions for the userfaultfd system call were denied. But if I specify the netCDF driver, the format is not recognized. Downloading the
dataset and opening It locally works.<o:p></o:p></span></p>
