Because of this separation, it is possible to add, delete, or change map information without first having to stop and start the automountd daemon process.

HOW TO CONFIGURE AUTOFS (AUTOMOUNT) IN LINUX

This preference is only checked if there are more version 3 servers than version 2 servers. Stop the autofs daemon sudo service autofs stop Run automount in the foreground with verbose information sudo automount -f -v From another terminal, try to mount your file-systems by changing directories into the mountpoint. Pings the server’s mount service to see if it’s alive. Most applications written for any of automouny sun4 architectures can run on all sun4 platforms, so the -ARCH variable is hard-coded to sun4 instead of sun4m.

Autofs selects the nearest interface to the client. Refer to “Autofs Unmounting” for an explanation of this limitation. The numbers in parentheses indicate a weighting. But remember that you need to access a directory before it is auto-mounted.

We can set time for after what time the filesystem unmount automatically once user stop using the mountpoint. You don’t want to modify files on one server on one occasion and, minutes later, modify the “same” file on another server.

How Autofs Works (System Administration Guide, Volume 3)

Figure How Autofs Uses the Name Service The screen activity for this session would look like the following example. You can modify auttofs maps at any time.

Auyomount the output from the first terminal for clues as to why the mount failed or was not attempted. Figure Navigation Through the Master Map Autofs Mount Process What the autofs service does when a mount request is triggered depends on how the automounter maps are configured. Be sure that you understand the security implications of this before proceeding. Do not use the -soft option when specifying hierarchical layers. During the sorting process, a count of the number of servers supporting the NFS version 2 and NFS version 3 protocols is made.

How Autofs Works

Autofs searches a series of maps to navigate its way through the network. They are points under which file systems are mounted in the uatofs. Subsequent references to the gowto are redirected by the autofs–no further participation is required by automountd until the file system is automatically unmounted by autofs after a period of inactivity.

If several servers supporting the same protocol are on the local subnet, the time to connect to each server is determined and the fastest is used. What the autofs service does when a mount request is triggered depends on how the automounter maps are configured.

Whichever protocol is supported on the most servers becomes the protocol supported by default. If the file system is busy, the unmount fails and the trigger nodes are reinstalled. Which server you mount them from does not matter, as long as the server is running and exporting its file systems.

Now the same entry for all clients applies to all architectures. Autofa is a simplified overview of how autofs works: During the unmounting process, any trigger nodes are removed and then the file system is unmounted. Note – Mounts managed through the autofs service should not be manually mounted or autofx.

You create maps to meet the needs of your environment using the Solstice System Management Tools. Not only is the best server automatically determined, but if that server becomes unavailable, the client automatically uses the next-best server.

Here we are using Autofs to mount the NFS exported shares automatically. One solution to this would be to create separate entries for each autoomount, as follows: The automount command is controlled within a domain and on computers through the name space or local files.
