Simple Autofs Mount

To help explain the autofs mount process, assume that the following files are installed.


$ cat /etc/auto_master
# Master map for automounter
#
+auto_master
/net        -hosts        -nosuid,nobrowse
/home       auto_home     -nobrowse
/share      auto_share
$ cat /etc/auto_share
# share directory map for automounter
#
ws          gumbo:/export/share/ws

When the /share directory is accessed, the autofs service creates a trigger node for /share/ws, which is an entry in /etc/mnttab that resembles the following entry:


-hosts  /share/ws     autofs  nosuid,nobrowse,ignore,nest,dev=###

    When the /share/ws directory is accessed, the autofs service completes the process with these steps:

  1. Checks the availability of the server's mount service.

  2. Mounts the requested file system under /share. Now the /etc/mnttab file contains the following entries.


    -hosts  /share/ws     autofs  nosuid,nobrowse,ignore,nest,dev=###
    gumbo:/export/share/ws /share/ws   nfs   nosuid,dev=####    #####
