NFS: can't see the mounted drives of machine 1 on machine 2

b0nd · 10-26-2005, 04:15 AM

hello all,
i've 2 machines. Both are running slackware 10.0.
i've configured NFS for lan sharing.
now the command which i use for mounting 2nd system on 1st is:

Code:

#mount 192.168.x.x:/ /mnt/client

where client is a directory in 1st system

but it let me see only the /root partition i.e only etc, mnt, usr...........and so on.
it do not let me see the partitions which other system has mounted.

what i think is that problem is with that command.
b'coz it seems that i'm mounting only the root.

Now if its the case then how should i mount the mounted drives.

e.g suppose 2nd system has /mnt/software........then how should i mount it ???

NOTE: all that partitions are "linux" type and not the fat/fat32.

regards

I think you may need the "nohide" option in the file /etc/exports on the first machine. See man exports.

Alternatively you could just exports the bits you need and thus not have to cross mount points - normally you would only export / (as read only) for the purposes of doing backups. Exporting / as read/write it is very easy to get confused about where you are and delete something inopportune!

Hope this helps,

All the best,
Karl

Hello,
this is the entry in /etc/exports........
where should i edit that "nohide" option ???

Code:

# See exports(5) for a description.
# This file contains a list of all directories exported to other computers.
# It is used by rpc.nfsd and rpc.mountd.

/ 192.168.x.x(rw,no_root_squash)

and i'm not clear with that alternative method.

The nohide option just goes in the brackets like the others:

/ 192.168.x.x(rw,root_squash,nohide)

The danger with this is that you may inadvertantly delete something from your remote system, as in:

"Hmmm, got a lot of crap in /mnt, just tidy it up...."
rm -rf /mnt/*
"Ooops... just deleted everything on my other system!"

The alternative method I talked about is to export and mount just the directories you are using, for example:

# Export everything read-only to one host so it can take complete backups
/ 192.168.1.10(ro,root_squash,sync)
# Export my home directory to my laptop, mounted as /home/krw/remote on the laptop
# i.e. mount -t nfs desktop:/home/krw /home/krw/remote
/home/krw laptop1(rw,root_squash,sync)
# Export public directory to the whole subnet to share software etc.
/home/public 192.168.x.x(ro,root_squash)

Hope this helps,
Karl

viewers should notice that i've set the path upto the directory where i've mounted my drives
