I had the same message until I exported a mount point that had no spaces in it. I was using: # /etc/fstab /mnt/My\040Book /export/My\040Book none bind 0 0 # /etc/exports /export/My\040Book 10.0.0.0/24(rw,nohide,insecure,no_subtree_check,async) But it worked with: # /etc/fstab /mnt/My\040Book /export/MyBook none bind 0 0 # /etc/exports /export/My Book 10by elecnix - Debian
