Verbose mount

Try to mount with -v (verbose)

showmount

Use

showmount -e

on the server to see what is exported.

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.
