Currently I am using on the OSX clients: nfs://192.168.0.100/Volumes/Storage to mount the NFS share.
My problem is why would all the data (and I have checked using various monitoring tools bmon, iftop, glances, etc) be going over the slower connection??
Also, after configuring /etc/network/interfaces with the above setup I always get an error message at bootup something about waiting for network configuration. Are these connected?
