I'm trying to setup a new diskless solution with ubuntu 12.04 without any success. I followed this Diskless Ubuntu HowTo



But the initramfs seems not to be able to mount my nfs share.



On my server side:



My /etc/exports




/srv/nfs4 192.168.0.0/24(fsid=0,rw,no_subtree_check)

/srv/nfs4/nfsroot 192.168.0.0/24(rw,no_root_squash,no_subtree_check,fsid=1,nohide,insecure,sync)


I'm able to mount my nfs share on standard Ubuntu installation without any problem.



I can mount my nfs on any client with those commands:



mount 192.168.0.3:/nfsroot /mnt


or



mount 192.168.0.3:/srv/nfs4/nfsroot /mnt


My /tftpboot/pxelinux.cfg/default config file is



DEFAULT vmlinuz-3.5.0-25-generic root=/dev/nfs initrd=initrd.img-3.5.0-25-generic nfsroot=192.168.0.3:/nfsroot ip=dhcp rw


I also tried

What I got in initramfs:



With the setting [nfsroot=192.168.0.3:/nfsroot]



Diskless output:



mount call failed - server replied: Permission denied


On Syslog of my nfs server:



rpc.mountd[1266]: refused mount request from 192.168.0.10 for /nfsroot (/): not exported


With the setting [nfsroot=192.168.0.3:/srv/nfs4/nfsroot]



Diskless output:



mount: the kernel lacks NFS v3 support


On Syslog of my nfs server I got:

          Your first attempt seems to be wrong because the full path is not specified.



          Your second attempt seems to be that there is a mismatch in nfs versions: The initramfs loads version 4 but the server only serves version 3.



          Probably this might help:

          Maybe issue with the files, did you use cp -ax to copy the files from the DVD/image to NFS. See http://ubuntuforums.org/archive/index.php/t-921313.html



          Or, it will automatically unmount the given NFS share when it doesn't find the kernel stuff it is looking for.



          You might need the boot=casper or similiar. Check your NFS directory structure. dirname find /nfs -type f -name "*linuz*"

            • And when I list my mount, I can see: 192.168.0.3:/nfsroot on /mnt type nfs4 (rw,addr=192.168.0.3,clientaddr=192.168.0.2)

              Yes, since the module is not present in the initramfs. Perhapse replace root=/dev/nfs with rootfstype=nfs4 root=/dev/nfs4

            But when I try to mount my nfs share remotely I can mount with nfs V4: mount -t nfs4 192.168.0.3:/nfsroot /mnt.

            Maybe issue with the files, did you use cp -ax to copy the files from the DVD/image to NFS. See http://ubuntuforums.org/archive/index.php/t-921313.html



            Or, it will automatically unmount the given NFS share when it doesn't find the kernel stuff it is looking for.



            You might need the boot=casper or similiar. Check your NFS directory structure. dirname find /nfs -type f -name "*linuz*"
