[Binu_5]

Hi All

This is regading an auto mount problem that Iam facing here ..We have configured automount using amd service and all where working fine ...Now for a couple of system automount is not happening but for other system they are working

Can any one tell which are the config files I have to check ....


Thanks

How about starting with some details.

First, what are you auto-mounting?

What errors are you getting?

What do your logs say for the time you are attempting the mount?

What's the configuration of the automount path you are using?

You're not really given us much information wo work on here.

Also, what version of the auto-mouter are you using? The distribution version or the latest eratta version?

Hi Staurt

All these systems coming with preloaded configuratiom from our client ...
So I dont have much Idea about it .
Can you tell which are the files I should check


Thanks

You should check the /etc/auto.master, this file holds references to other files, like /etc/auto.misc.

You should ensure that the automount service is configured to start on boot with the chkconfig command.

Ivan, unfortunately, that's the wrong auto-mounter ;)

Binu, do these:

rpm -q am-utils
cat /etc/amd.conf
chkconfig --list amd
chkconfig --list autofs
mount

And copy all output back into here. This will give us a decent over-view of how your system is configured to behave.

Hi Stuart

Please find the following information

rpm -q am-utils
am-utils-6.0.9-2
cat /etc/amd.conf

And just for completion sake, the contents of 'amd.hosts' (should be '/etc/amd.hosts').

[Binu_5]

Hi Stuart

I have checked the amd.conf file of working and non working systems ...Both are identical ...


Thanks

Well I want to verify what's in the '/etc/amd.hosts' file to besure of some options, but..

I'd like you to check the permissions and contents of '/home' and '/net' when the auto-mounter isn't started (i.e. stop 'amd' and then check).

I'd also like for you to find out what '/var/log/amd.log' says at the time of one of your failures occurs.

Do any error messages show up in the terminal session that is accessing information in the auto-mounted path? Also, were there any network failuers?

Also, cross-refence any errors to the server's log files for the same time, to see why the server thought the mount went away.

It is more than likely a network/NFS error in general rather than an auto-mounter failure, but.. There's always things to check ;)
