Verbose mount
Try to mount with -v (verbose)

Use
showmount -e
on the server to see what is exported.
Failures
mount hangs
I've seen cases when trying to mount a filesystem from other machine hangs if nfs is not started on that machine (service nfs start).
mount.nfs: access denied by server while mounting
I've also seen cases when I get the following error message when not using -t nfs, so use -t nfs:
mount.nfs: access denied by server while mounting f01:/opt/shared
mount(2): No such file or directory
mount -v yields:
mount.nfs: trying text-based options 'bg,vers=4,addr=172.31.20.184,clientaddr=172.31.21.24' mount.nfs: mount(2): No such file or directory ...
I get this because I use the wrong exported path in /etc/fstab.
mount(2): No route to host
mount -v yields:
mount -v -t nfs 192.168.1.2:/volume3/dropbox /mnt/tmp mount.nfs: timeout set for Sun Aug 21 00:44:48 2016 mount.nfs: trying text-based options 'vers=4,addr=192.168.1.2,clientaddr=192.168.1.9' mount.nfs: mount(2): No route to host
