Configuring AutoFS

  • Automatically mount NFS file systems when needed.
  • Automatically unmount NFS file system that are no longer being accessed. There is a 5 minutes timeout.
  • May be configured to provide load balancing across multiple NFS servers.

Enable AutoFS

AutoFS is enable in the "/etc/rc.config.d/nfsconf" using the [ AUTOMOUNT | AUTOFS ] variable. The AUTOMOUNTD variable can be use to add additional flags to the start script, like "-v" or "-T".

The -T flag Expand each RPC call and display it to /var/adm/automount.log.

The -v flag increases the verbosite of the log status messages to /var/adm/syslog/syslog.log.

  • Note: Don't enable AUTOMOUNT and AUTOFS at the same time.

Configuring the "-hosts" map

Edit "/etc/auto_master" file and add the configuration line "/net -hosts - soft,nosuid".


Example:

-> /etc/auto_master
/net -hosts -soft,nosuid

Direct Map

-> /etc/auto_master
/- /etc/auto.direct
-> /etc/auto.direct
/usr/contrib/games      -ro     gamesvr:/usr/contrib/games
/opt/tools              -ro     toolsvr:/opt/tools
/var/mail               -rw     mailsvr:/var/mail

Indirect Map

-> /etc/auto_master
/drawings /etc/auto.drawings
-> /etc/auto.direct
gizmos                  -ro     gizmosvr:/drawings/gizmos
gadgets                 -ro     gadgetsvr:/drawings/gadgets
widgets                 -rw     widgetsvr:/drawings/widgets
