We get this problem on servers 12.04.5 running Trusty kernel 3.13.0-65-generic (and on 12.04.4 running Quantal kernel 3.5.0-54 )
/etc/fstab has a slash at the start of the NFS server path
/proc/mounts has an unnecessary extra "/" on the NFS path: like this :-
nfs-server://home/users /export/home/nfshomes nfs4 .....
whereas /etc/mtab correctly does not ...
nfs-server:/home/users /export/home/nfshomes
This is a nasty bug in a basic utility (umount.nfs) and really should be fixed !!
