Dear Geoserver Users list
I'm looking for a way to upload our Netcdf files with the Netcdf-plugin to
GeoServer (Version 2.11.5).
The plugin works well with with CF and COARDS sample data from
https://www.unidata.ucar.edu/software/netcdf/examples/files.html
However, when I try to upload our own Netcdf files, I receive an error when
saving the store.
Could not list layers for this store, an error occurred retrieving them: Failed
to create reader from
file:coverages/testLennertS/log.x5.20132013.0103.10001.10001.anl.nc and hints

I looked up the documentation for netcdf files and this maillist archive, and
tried different things, for example to explicitly add the 'nv' dimension as a
variable (now 'nv' is only a dimension), but without success.
Does anyone know what (part) of my netcdf files are currently not supported?
Or where can I find more information?
Thanks a lot
