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.

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) SunOS 5.11 6 May 2003 unshare_nfs(1M)
