Yes, as Boaz said, having two exports with fsid=0 is the problem:

 >   # cat /etc/exports
 >   /nfstest   192.168.100.0/255.255.255.0(fsid=0,rw,async,insecure,no_root_squash)
 >   /mnt       192.168.100.0/255.255.255.0(fsid=0,rw,async,insecure,no_root_squash)

you could have seen this in the server log from this:

 >   Nov 21 20:47:37 dell1435 mountd[3575]: /nfstest and /mnt have same
 > filehandle for 192.168.100.0/255.255.255.0, using first
