[SOLVED] NFS is not mounting automatically @boot time

sjremya · 08-30-2010, 08:14 AM

Hi all

I am trying to mount NFS for my embedded application. I could mount the NFS manually using mount command as follows :

mount -t nfs -o nolock 192.168.174.134:/nfs/nfs_point/ /mnt . This works fine.

I have to do the same thing in system boot up, in my ARM linux. I modified /etc/fstab as follows to achieve this :

192.168.174.134:/nfs/nfs_point /mnt nfs _netdev,rw 0 0

But when I tried to mount it only using 'mount <mount_point> ' ie. mount /mnt, its throwing me the following error.

portmap: server localhost not responding, timed out
RPC: failed to contact portmap (errno -5).

Please help me out to solve this issue

regards

Do you launch RPC deamon on server and client?

@nini09 . thanks ....

sorry ... i do not know it in depth .... But I could solve this issue

[ i.e. not able to add nfs details in /etc/fstab]. My entry in /etc/fstab is as follows:

192.168.174.134:/nfs/nfs_test /mnt nfs rw,soft,bg,timeo=3,intr 0 0

I have mounted device after staring portmap as follows [ Entered this commands manually in the command prompt]

#portmap &
#mount /mnt </mnt is the mount point as in /etc/fstab>

Its working fine . But my problem exists still. I do not want to enter this commands manually in the command prompt.
I want to start all applications in the boot time itself.

Where can I add this command? It must run after reading /etc/fstab. Can I make an rc.local file and update it with the mount command?

I hope rc.local will work. But I could not see that file in my root filesystem? Is it a system generated file?

Please guide me with a good way to achieve this. Any other way there to make this command entry?

Thanks in advance & Regards

Hi

I could add this mount command in the newly created /etc/rc.d/rc.local file and run it manually by

/etc/rc.d/rc.local start

How to run this file automatically in the boot time itself ??

Please help me

What's your distribution, Fedora or something else?

its open suse...

I could not find rc.local or boot.local file( where we can add local commands) in its /etc/ directory.

So I thought of modifying /etc/fstab with the entry

192.168.174.134:/nfs/nfs_test /mnt nfs rw,soft,bg,timeo=3,intr 0 0

Its succeeding ONLY when I give

mount /mnt command manually ....

I feel /etc/fstab is not running before network fires up. So NFS is failing. How to make it sure that my network is working properly ?

Hi all

Happy to say that i solved NFS mounting problem in system boot up

. Thank you all for your valuable suggestions.

It was a simple network problem. When I tried to mount NFS in /etc/init.d/rcs, network was not initialized properly. I have changed the position of network bringup to top (ifconfig eth0 <ip_addr> netmask <net_mask> up) in /etc/rc.d/rcS and gave some delay to establish network. At last i did NFS mounting using mount command.

mount -t nfs -o nolock <distant_machine> <my_mnt_pint> . It works fine.

But I wasted my time to look into fstab file to implement it

. It is so easy to implement in rcS file.
