After a bit of research into:

Code:
export -p

In a POSIX shell "export -p" lists the currently exported values.
It does nothing else, even with parameters after the "export -p".

Code:
Compare:
# Proper use of export
unset hello
export hello="hello"
export -p | grep "hello"
# Improper use of export
unset hello
export -p hello="hello"
export -p | grep "hello"

Suggest you remove the "export -p" which precedes each assignment of environment variables in your script because it is stopping the assignment taking place. Besides which there is no point to using "export" in this shell context.

unshare_nfs

unshare_nfs(1M) 					  System Administration Commands					   unshare_nfs(1M)

NAME

       unshare_nfs - make local NFS file systems unavailable for mounting by remote systems

SYNOPSIS

       unshare [-F nfs] pathname

DESCRIPTION

       The  unshare  command makes local file systems unavailable for mounting by remote systems. The shared file system must correspond to a line
       with NFS as the FSType in the file /etc/dfs/sharetab.

OPTIONS

       The following options are supported:

       -F    This option may be omitted if NFS is the first file system type listed in the file /etc/dfs/fstypes.

FILES

       /etc/dfs/fstypes

       /etc/dfs/sharetab

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWnfssu 		   |
       +-----------------------------+-----------------------------+

SEE ALSO

       nfsd(1M), share(1M), attributes(5)

NOTES

       If the file system being unshared is a symbolic link to a valid pathname, the canonical path (the path which  the  symbolic  link  follows)
       will be unshared.

       For  example,  if  /export/foo is a symbolic link to /export/bar (/export/foo -> /export/bar), the following unshare command will result in
       /export/bar as the unshared pathname (and not /export/foo):

	 example#  unshare -F nfs /export/foo

       For file systems that are accessed by NFS Version 4 clients, once the unshare is complete, all NFS Version 4 state  (open  files  and  file
       locks)  are  released and unrecoverable by the clients. If the intent is to share the file system after some administrative action, the NFS
       daemon (nfsd) should first be stopped and then the file system unshared. After the administrative action is complete, the file system would
       then be shared and the NFS daemon restarted. See nfsd(1M)
