Diskless with Ubuntu 12.04
- by user139462
I'm trying to setup a new diskless solution with ubuntu 12.04 without any success. I followed this howto:
https://help.ubuntu.com/community/DisklessUbuntuHowto
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
DEFAULT vmlinuz-3.5.0-25-generic root=/dev/nfs initrd=initrd.img-3.5.0-25-generic nfsroot=192.168.0.3:/srv/nfs4/nfsroot ip=dhcp rw.
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:
Mar 11 14:03:06 BootFromLan rpc.mountd[1266]: authenticated mount request from 192.168.0.10:834 for /srv/nfs4/nfsroot (/srv/nfs4/nfsroot)
Mar 11 14:03:06 BootFromLan rpc.mountd[1266]: refused unmount request from 192.168.0.10 for /root (/): not exported
