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

SEE ALSO

attributes(7), nfsd(8), share(8)

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(8)
