Do you have ny shells that have cd into one of the nfs dirs, or ny
processes that are trying to read/write to any of the dirs?

Check out lsof and find processes looking to do things in the NFS volume
and kill them or make then stop/change dirs out of that volume.
 (eg:)
# lsof | grep "/nfs/mounted/volume" | less
