Hi Ben
Thanks for testing on your side as well. I am a bit stuck here, as moving
a large volume of data files across to a machine not meant to store them
does not seem like a good option. It also means that we cannot use one
GeoServer instance to "point" to multiple locations unless we can get
symlinks to work.
Any other ideas or tests I can run?
Thanks
Derek
