Mounting issue after NFS boot emergency mode [solved]

Hi,

Changing the U-boot default parameters, I managed to boot the linux LXDE image from network as described in the link below. I set exactly the same network config.
https://developer.toradex.com/knowledge-base/linux-booting#UBoot_on_NAND_Flash_Kernel_from_TFTP_and_Rootfs_from_NFS

Sorry for the long post, there is a lot of log. I don’t want to remove any useful information.

The TFTP and NFS server config:

$ cat /etc/exports 
# /etc/exports: the access control list for filesystems which may be exported
#		to NFS clients.  See exports(5).
#
# Example for NFSv2 and NFSv3:
# /srv/homes       hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check)
#
# Example for NFSv4:
# /srv/nfs4        gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check)
# /srv/nfs4/homes  gss/krb5i(rw,sync,no_subtree_check)
#

/srv/nfs 192.168.10.1/24(no_root_squash,no_subtree_check,rw,fsid=root)
$ cat /etc/default/tftpd-hpa 
# /etc/default/tftpd-hpa

Some variables seemed wrong, so I corrected them. Then it booted:

setenv nfsargs 'root=/dev/nfs rw nfsroot=192.168.10.1:/srv/nfs,nolock,v3,tcp ip=192.168.10.2:192.168.10.1:192.168.10.1:255.255.255.0:toradex::off'

setenv bootcmd 'run nfsboot ; echo ; echo nfsboot failed ; setenv fdtfile ${soc}-colibri-emmc-${fdt_board}.dtb && run distro_bootcmd;'
boot

After booting, the console showed the lines below. It’s the full log with the command I entered.

I assume there is problem to mount other fs as said by the log and journalctl.

Many thanks in advance !

Finally I solved the problem myself.

I had to copy the rootfs to /srv/nfs with root user.

Glad you got it solved and thanks for the feedback!

Hi @arnaud_infoteam
Can you please elaborate how to do this ? i am having the same problem, the kernel goes into the Emergency mode.
I copied the files as a root user. Is that what you meant by the answer or something else ?
Thanks.

Yes exactly !

But I haven’t use yocto for a long time. I use buildroot. But the command should be similar:

sudo tar xvf output/images/rootfs.tar -C /srv/nfs/

If you have the emergency mode. That might mean the kernel is just unable to mount the rootfs. So check whether the nfs server is running correctly.

@arnaud_infoteam
This worked out.
Thank you.

@mtlc you’re welcome. I’m glad to see other persons stuck with same problems
