RHCT RHCE Exam :RHEL4 NFS issues :
Many times you have NFS exported directories mounted on Linux server get hanged. Possible sided affects just find out on my test Redhat Linux server running RHEL4 AS update 3 df start hanging. Pretty annonying . Trouble part is how to get rid off hanging df issues and find outr why it's happening.
NFS mounts are hanging simply because Server exporting NFS mount is offline or not on network. Again let's say you have 50 0r more mount point mounted on your NFS Linux client machine. You have to compare nfs mount showing in df comand output and nfs mount listed in /etc/fstab. once you find out what NFS mount is hanging you can simply go in /etc/rmtab file and remove that mount point.... and guess what you just resolved hanging nfs mount issue .

you can use
root# umount -f {mount point}
-f is for offline nfs mounts
