One problem might be the "root squashing" NFS servers generally do.

For example, on the server I NFS export /extra and mount it on several other
computers.

If as shackle I create a directory under /extra I can read and write it as
shackle when I access it from other computers.

But if as root I create a directory under /extra I can only read and write it
from other systems as root if the the permissions  allow anyone to read or
write the directory. The reason is that most NFS servers squash root access so
that remote root users are considered "nobody" when accessing files.

If you have access to the servers /etc/export file you can add "no_root_squash"
option, otherwise you may have to make sure you are not root when accessing
network mounted drives, or use chmod a+w  to allow everyone to access the
files/directories.
