NFS Client not starting

Suni Raj — Mon, 26 Mar 2007 17:49:28 GMT

One of my NFS client is giving the error when I try to start the NFS client:

# /sbin/init.d/nfs.client start
starting NFS CLIENT networking

starting up the rpcbind
rpcbind already started, using pid: 28068
starting up the BIO daemons

Can anyone tell me why this is happening and how to solvde it.

It seems that when you start the NFS client, it tries to start several related daemons, for example, it checks for /etc/exports (Server side), and also, tries to start autofs, an automounter daemon. Probably, the /etc/auto_master does not exists or is not configured.

What do you want to achieve? Probably, if you correctly set the /etc/fstab file, the NFS file systems should be mounted, as no errors reported when mounting remote NFS file systems.

Could you tell me what I need to add to /etc/fstab file? The application team needs a /net file system to mount. I can cd to the /net, but when I do a ls -l , it shows 0 files.

If /net directory is under automounter control, when you try to acess it first time automounter will mount it. As i could see FAILURE CODE 2 ( file doesnt exists) first thing you need to check whether automount master map file exists in /etc/auto_master directory.

You may want it manually mounted then follow the following steps:

mount server_name:/net_related_dir_exported /net

If you have a working client, copy the /etc/auto_master file to this client, if you don't, see:

Thanks for the wonderful automount .pdf file location.

Looks like your thread went to the wrong Forums' section.
The nfs client you are talking about obviously isn't of Linux origin but rather HP-UX.
Anyway, usually for automounted host mounts beneath /net, on the nfs client all that's required is a mapping like this

# grep ^/net /etc/auto_master
/net -hosts -nosuid,soft,nobrowse

also the nfsconf must be prepared to start automounter on the client like so

# grep -E '^(NFS_CLIENT|AUTO)' /etc/rc.config.d/nfsconf
NFS_CLIENT=1
AUTOMOUNT=1
AUTO_MASTER="/etc/auto_master"
AUTO_OPTIONS="-f $AUTO_MASTER"

# /sbin/init.d/nfs.client start
(after the nfs.core) should start the stuff.

# UNIX95= ps -o user,pid,ppid,args -C automountd
USER PID PPID COMMAND
root 901 1 /usr/lib/netsvc/fs/enh_autofs/automountd

On any nfs server export a filesystem to the box where autounter runs.

Then access this export from the nfs client via the /net/ mapping,
and automunter should dutyfully mount the share (if not already mounted).
