Solaris Automount


Automounter also has built in debugging, which can be used to examine exactly what the automounter is doing. How Autofs Starts the Navigation Process (Master Map) The automount command reads the master map at system startup. After the autofs mounts are set up, these mounts can trigger file systems to be mounted under them. Auto FS Managing NFS Server: We use NFS server files, NFS server daemons & NFS server commands to configure and manage an NFS server. Check This Out

For more information about roles, see Configuring RBAC (Task Map) in System Administration Guide: Security Services. For task information, refer to Using the /etc/default/autofs File to Configure Your Autofs Environment. If the map name starts with a dash (-), automount consults the appropriate built-in map, such as hosts. So, the above would work fine if you were using NIS, and the actual NIS map was auto.home.

Solaris Automount

Solution: Check the NIS server status.mount of server:pathname on mountpoint:reason Description: Autofs failed to do a mount. rw=acess-list:Allows read & write requests from specified access list. You can modify autofs maps at any time.

These users are provided with direct access to local files through loopback mounts instead of NFS mounts. Note - The first time you configure your system for NFS version 4, a warning appears on the console to indicate that caching is no longer performed. The working of the nfs file system is as easy as the locally mounted file system. Only the mounted resources are visible. -browseoption allows all potential mount points to be visible.

Each line of dfstab file consists of a share command. Autofs Press Ctrl+D to continue normal boot. 4. Q: Solaris automounter, can't seem to mount a directory in certain cases. http://docs.oracle.com/cd/E23824_01/html/821-1454/rfsrefer-75.html Instead of mounting a file system from a server, you put the media in the drive and reference the file system from the map.

You can use the NFS mount option of "retry=N" to give the automounter some retry attempts. Your system probably will still have some performance problems which SunService is unable to help you resolve. Start the nfs server daemon: #svcadm enable nfs/server At Client side: 1. This procedure is sensible only when you mount a file system that is read-only, as you must have some control over the locations of files that you write or modify.


By default these values are unspecified. Accessing Non-NFS File Systems Autofs can also mount files other than NFS files. Solaris Automount You must still wait for already mounted partitions to get umounted in orderto see changes on them. Figure6-4 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.

Every Solaris installation comes with a master map: /etc/auto_master. # Master map for autofs # +auto_master /net -hosts -nosuid,nobrowse /home auto_home -nobrowse A map for auto_home is also installed under /etc. http://atomirc.net/solaris-10/solaris-10-dns-client.html This process allows system administrators to change mount information within auto_master and have those changes used by the autofs processes without stopping and restarting the autofs daemon. IMPORTANT: you may NOT specify "-null" anywhere EXCEPT the master map! Afterwards, it includes a special net map, which is described in the man page, and also a /home indirect map, which is read from the naming services.] # cat /etc/auto_home +auto_home

These mounts are points under which file systems are mounted in the future. Notification is required so that the users can also run the automount command as superuser on their own computers. This will give the automounter "N" more retries at the mount (spaces 15 secs apart. this contact form How to Replicate Shared Files Across Several Servers The best way to share replicated file systems that are read-only is to use failover.

The following line increases the automount timeout to 3600 seconds, or 60 minutes: /usr/sbin/automount -t 3600 # do mounts The above two fixes are only workarounds. Resolution: 1. If /usr/src is not mounted at this time, the new entry becomes effective immediately when you try to access /usr/src.

However, if both the client and the server are running NFS version 4, the functionality is as follows.

Correct this in files/NIS/NIS+/DNS as appropriate. 4.3: Automount Runtime Errors Q: What does the following error mean: "automountd: server [machine] not responding" A: This correlates to the standard "NFS server [machine] mount: Attaches a file resource(local/remote) to a specified local mount point. Updating Automount Maps: After making changes to master map or creation of a direct map, execute the autmount command to make the changes effective. #automount [-t duration] [-v] -t : Specifies Here are some examples of how the sorting process works: Servers on the local subnet are given preference over servers on a remote subnet.

The specific order of the entries is not important. The override happens because the +auto_master reference to the external name service map occurs before the /home entry in the file. In the previous example, multiple mount locations are expressed as a list of mount locations in the map entry. /usr/man -ro oak:/usr/man rose:/usr/man willow:/usr/man In this example, you can mount the navigate here CAUTION: this can "hold up" other automount requests for 15 seconds per retry specified, on some versions of Solaris.

This arrangement provides the administrator with much flexibility. If the remote file system is not accessed for a defined period of time, it is unmounted by automountd daemon.
