Automounting under amd

Using the amd automounter under Sun OS, you can cause any or all of the CD-ROM diskettes to be automatically mounted on your work station when they are requested by any user. The contents of the CD-ROM diskettes will appear as Unix file systems, for example /CEDRCD/disk1, disk2... etc.

An advantage of amd over fixed NFS mounting is that remote file systems are mounted only when needed. Recovery from network interruptions is automatic and trouble-free. In addition, changes in NFS locations can be incorporated in an CDROM_map that can be automatically broadcast to your location from LBL whenever it is updated. For further information, contact Mike Helm (m_helm@lbl.gov).

A disadvantage is that automounting is more complicated than fixed NFS mounting. Furthermore, the automounted file systems are invisible until they are requested; they are not revealed by typing

	ls /CEDRCD
File systems mounted with amd cannot be exported via anonymous ftp.

Installation and Use

In your work station, your amd requires a file which should be a current copy of LBL's file /etc/Custom/CDROM_map . A recent version is in the public location http://merrill.wwh.net/cdrom/install/CDROM_map

At LBL, the file /etc/Custom/CDROM_map is maintained by running the current version of http://merrill.wwh.net/cdrom/install/Makefile_mount

on the latest version of http://merrill.wwh.net/cdrom/install/CDROM.list

which corresponds to the public file http://merrill.wwh.net/cdrom/install/nfsloc.online

Consult your system manager for assistance in installing and configuring amd. Once amd is properly installed with a current version of LBL's CDROM_map, any user of your work station can automatically mount any CD-ROM by typing (for example)

	cd /CEDRCD/disk1
