NFS boot issues

Hi,

for nfs booting, the kernel nfs related boot command argument should be same as the exported directory name .

in your case

I have modified in /etc/exports the following line:
      /home/kumar/AM1808/filesys *(rw,sync,no_subtree_check)

and
kernel command line argument are different
bootargs=console=ttyS2,115200n8 noinitrd rw ip=192.168.1.100:192.168.1.200:192.168.1.1:255.255.255.0::eth0:off
root=/dev/nfs nfsroot=192.168.1.200:/targetNFS, nolock mem=32M

To correct it, change kernel command line argument as
bootargs=console=ttyS2,115200n8 noinitrd rw ip=192.168.1.100:192.168.1.200:192.168.1.1:255.255.255.0::eth0:off
root=/dev/nfs nfsroot=192.168.1.200:/home/kumar/AM1808/filesys, nolock mem=32M

Hi Gururaja,

Those environment variables are old one. As per your suggestion, i have modified the same thing but i got the same message:

Please suggest me to resolve NFS issues

Since u-boot can get uImage via TFTP, we can assume the HW connection is good. The boot messages suggest that the NFS processes are still being blocked. Are you running the iptables firewall? My experience is with Fedora and on that distro the firewall is disabled with:

service iptables stop

I've never checked this but supposedly the file "/var/log/secure" should have messages about connections being rejected. You could try "ALL:ALL" in your "hosts.allow" file. Not a secure setup for the long term. I think it's okay for a few quick tests.

Your target will need to connect as root. Your exports file should avoid squashing root access. Something like:
/home/kumar/AM1808/filesys *(rw,no_root_squash,no_all_squash,sync)

You might have other problems with the the filesys directory itself. Depends how you created it.

Your network may not be coming up fast enough. Try adding "rootdelay=4" to the bootargs.

 

Hi,

I have added in my bootargs. Still it is showing error as rpcbind: server 192.168.1.200 not responding, timed out

Bootargs

setenv bootargs console=ttyS2,115200n8 noinitrd rootdelay=4 rw ip=192.168.1.100:192.168.1.200:192.168.1.1:255.255.255.0::eth0:off root=/dev/nfs nfsroot=192.168.1.200:/home/kumar/AM1808/filesys, nolock mem=32M

Can i know further steps to resolve this issue. Is there any problem with my File system(dowloaded from TI http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/sdk/omap_l138/1_00/latest/index_FDS.html )

Thanks
Francis

I would guess your file system is okay.Won't know until NFS is up. NFS should not care at this point. If the NFS server has this

rpcinfo -p
    100003    2   udp   2049  nfs
    100003    2   tcp   2049  nfs
    100005    1   udp  56583  mountd
    100005    1   tcp  41591  mountd

then the client should show

Looking up port of RPC 100003/2 on 192.168.1.200
Looking up port of RPC 100005/1 on 192.168.1.200

without errors.

Your bootargs may have a extra space in the nfsroot parameter. I think it should be

nfsroot=192.168.1.200:/home/kumar/AM1808/filesys,nolock

with no space between "filesys," and "nolock". I don't think it will solve your NFS problems.

I'm out of ideas. Something is still blocking. Hopefully some Ubuntu experts will speak up.

 

I noticed your hosts.allow has IP address 192.168.1.10, while your board is using 192.168.1.100.

Try allow all access first.

Hi,

My NFS issue is resolved. My filesystem is corrupted one. i have downloaded other one it got resolved.

Thanks for your support

Francis
