Boot your Dockstar by TFTP/NFS

Hi there!

A few month ago, I was trying to boot my dockstar by TFTP & NFS... but did not succeed.
I've left my dockstar on the side for a time, and I recently tried again successfully !

My deep gratitude to this fellow community who made it all possible by their numerous contributions !

Here's my modest contribution...

I tried this with a newly-installed debian wheezy distribution on my dockstar, the latest uboot, and a unmodified debian kernel.

This guide assumes that you already have a functionnal NFS, TFTP and DHCP server on your network.
In my example, I'm running the TFTP and NFS server on a NAS running Debian, and the DHCP server on a router running OpenWRT.

Here's how I proceeded

1. Install latest uboot on the Dockstar:

cd /tmp
wget http://projects.doozan.com/uboot/install_uboot_mtd0.sh
chmod +x install_uboot_mtd0.sh
./install_uboot_mtd0.sh

2. Install a fresh debian on the Dockstar using the well known Jeff's script, or try to use your existing dockstar installation.

3. Copy the dockstar rootfs on the NFS Server:

mkdir -p /mnt/usbdockstar
mkdir -p /srv/nfs/hosts/dockstar
mount /dev/<whatever-device-your-dockstar-rootfs-is-on> /mnt/usbdockstar
cp -av /mnt/usbdockstar/* /srv/nfs/hosts/dockstar/
umount /mnt/usbdockstar

4. Copy the dockstar boot files on the TFTP Server:

mkdir -p /mnt/usbdockstar
mkdir -p /srv/nfs/hosts/dockstar
mount /dev/<whatever-device-your-dockstar-rootfs-is-on> /mnt/usbdockstar
cp -av /mnt/usbdockstar/boot/u* /srv/tftp/nfs/dockstar/
umount /mnt/usbdockstar

5. Add the dockstar folder as shared folder on the NFS server:

if ! cat /etc/exports | grep /srv/nfs/hosts/dockstar >/dev/null; then
cat <<EOF >>/etc/exports
/srv/nfs/hosts/dockstar                 192.168.0.0/255.255.0.0(rw,sync,no_root_squash,no_subtree_check)
EOF
fi
exportfs -av

6. Make changes onto the dockstar rootfs hosted on the NFS server to allow it to properly boot by NFS:

# Define Dockstar RootFS location on NFS Server
ROOTFS=/srv/nfs/hosts/dockstar

#Change Root entry in /etc/fstab
sed -i 's;^/dev/root.*;/dev/root       /               nfs    noatime,errors=remount-ro 0 1;' $ROOTFS/etc/fstab

#Disable eth0 auto-configuration
sed -i 's;auto eth0;#auto eth0;' $ROOTFS/etc/network/interfaces

#Disable eth0 auto-configuration (ifplugd)
sed -i 's;eth0;;' $ROOTFS/etc/default/ifplugd;
sed -i 's;^\(INTERFACES\)="auto";\1="";' $ROOTFS/etc/default/ifplugd
sed -i 's;^\(HOTPLUG_INTERFACES\)="all";\1="";' $ROOTFS/etc/default/ifplugd

7. Create NetBoot variables in uboot on the Dockstar from the running Linux:
This will not yet alter the Dockstar startup configuration. All the following commands create non-existing variables into uBoot.

#NetBoot variables
# -User-Serviceable
fw_setenv net_dhcp_c '1'
fw_setenv net_dhcp_s '0'
fw_setenv net_c_ipaddr ''
fw_setenv net_c_netmask ''
fw_setenv net_c_gatewayip ''
fw_setenv net_tftp_server '192.168.1.1'
fw_setenv net_tftp_kernel 'nfs/dockstar/uImage'
fw_setenv net_tftp_initrd 'nfs/dockstar/uInitrd'
fw_setenv net_nfs_server '192.168.1.1'
fw_setenv net_nfs_path '/srv/nfs/hosts/dockstar'

# -Fixed
fw_setenv autoload 'no'
fw_setenv net_bootcmd 'run net_check_dhcp_c; run net_check_dhcp_s; run net_set_bootargs; run net_boot'
fw_setenv net_boot 'tftp 0x800000 $net_tftp_kernel; echo; echo ** Kernel Boot Arguments: $bootargs; echo;if tftp 0xe00000 $net_tftp_initrd; then bootm 0x800000 0xe00000;else bootm 0x800000;fi'
fw_setenv net_set_bootargs 'setenv serverip $net_tftp_server; setenv bootargs console=$console root=/dev/nfs rootfstype=nfs rootwait nfsroot=$net_nfs_server:$net_nfs_path ip=$ipaddr:$net_nfs_server:$gatewayip:$netmask:dockstar:eth0:off $mtdparts'
fw_setenv net_check_dhcp_c 'if test $net_dhcp_c -eq 1 ; then run net_set_c_ip_dhcp; else run net_set_c_ip_stat; fi;echo ** IP Address: $ipaddr; echo ** Subnet Mask: $netmask; echo ** Def Gateway: $gatewayip'
fw_setenv net_set_c_ip_dhcp 'dhcp; echo; echo ** net_dhcp_c = 1 --> Getting IP Settings by DHCP'
fw_setenv net_set_c_ip_stat 'setenv ipaddr $net_c_ipaddr; setenv netmask $net_c_netmask; setenv gatewayip $net_c_gatewayip; echo; echo ** net_dhcp_c = 0 --> Using static IP Settings'
fw_setenv net_check_dhcp_s 'if test $net_dhcp_s -eq 1 && test $net_dhcp_c -eq 1 ; then run net_set_s_ip_dhcp; else run net_set_s_ip_stat; fi;echo ** TFTP Boot Server: $net_tftp_server; echo ** NFS Boot Server: $net_nfs_server; echo'
fw_setenv net_set_s_ip_dhcp 'setenv net_tftp_server $serverip; setenv net_nfs_server $serverip;echo; echo ** net_dhcp_s and net_dhcp_c = 1 --> Getting TFTP and NFS Boot Server by DHCP'
fw_setenv net_set_s_ip_stat 'echo; echo ** net_dhcp_s or net_dhcp_c = 0 --> Using static TFTP and NFS Boot Server'

#NetBoot variables End

8. Now you need access to uBoot to test the TFTP/NFS boot.
You can either plug a serial adapter on your Dockstar or configure uBoot to send the information by netconsole
I used the first option, but here's the procedure for the second one, assuming your NetCat client runs on 192.168.1.250.

On the dockstar, enter:

fw_setenv netcatip 192.168.1.250
fw_setenv if_netconsole 'ping $netcatip'
fw_setenv start_netconsole 'setenv ncip $netcatip; setenv bootdelay 10; setenv stdin nc; setenv stdout nc; setenv stderr nc; version;'
fw_setenv preboot 'dhcp; run if_netconsole start_netconsole'

To receive the console on your computer, run:

nc -l -u -p 6666

9. Reboot the dockstar, interrupt the autoboot and execute

run net_bootcmd

It should boot your dockstar by TFTP and NFS.

10. If your boot attempt was successful, alter the dockstar boot sequence to try to boot by NFS with the following command:

fw_setenv bootcmd 'usb start; run force_rescue_bootcmd; run ubifs_bootcmd; run usb_bootcmd; usb stop; run net_bootcmd; run rescue_bootcmd; run pogo_bootcmd; reset'

It's a copy of the original boot command, altered to try to boot by NFS after it fails to boot by USB, but before it tries to boot the rescue_system.

Next time you reboot, your dockstar will boot by NFS if it cannot find a bootable USB storage.

EnJoY !


N.B.
In the current configuration, the dockstar will get an IP address by DHCP, but will boot from the statically defined TFTP & NFS server. If you want the dockstar to get the IP address of the TFTP & NFS server by DHCP, just change this:

fw_setenv net_dhcp_s '1'

The DHCP server should then provide the server address with the dhcp option 66
(known as 'TFTP server name' or 'next-server')

Alternatively, if there's no DHCP server on your network or the DHCP server gives faulty information (I had the case with a cable modem that returned an inexisting boot file in option 67), You can statically define your client IP settings with the following changes:

fw_setenv net_dhcp_c '0'
fw_setenv net_c_ipaddr '192.168.1.5'
fw_setenv net_c_netmask '255.255.255.0'
fw_setenv net_c_gatewayip '192.168.1.254'

In this case, you also MUST statically define the IP address for

fw_setenv net_tftp_server '192.168.1.1'
fw_setenv net_nfs_server '192.168.1.1'

Very nice!
I don't know if I'll ever use this myself, but you did a nice job of specifying details, documenting the scripts/code. Its always nice to see (yet another!) a reminder of the cool things one can do w/ code, some experimentation and some perseverance.

Hey! That's exactly what i was looking for!

But where is and where can i find 'boot/gpxelinux.0' file?

Thanks

Edit : i think i got it, this file is in the syslinux-common package... Nothing mentioned this in the tutorial... so going to "apt-get install syslinux-common"...
Edit2 : finally it seems that the uboot dhcp command is the problem because when i type help at the uboot prompt i have this :
dhcp - boot image via network using DHCP/TFTP protocol
and it's very strange... and when i type 'dhcp' it tries to load a image CA807.img or something like that!
So i modify the settings to have static ip - so no more dhcp, and i go one step ahead = Kernel booting, but no access to the dockstar ==> time to make a serial cable...

Edit3 : suppress the br0 bridged interface (was created to bridge an usb2ethernet network key) from /etc/network/interfaces .... It works !!!!! So the only problem was with the uBoot dhcp command, but i see in the log in the first message that there's the loading of gpxelinux.0 but i don't understand why?

Edit4 : Got it! The problem with the dhcp uBoot command trying to load an image can be changed by the uboot command 'setenv autoload no'. After that if i type 'dhcp' it gives me my ip without trying to load an image...

Edit5 : to make the 'set autoload no' permanent, i just change the line in the script :
from
fw_setenv net_set_c_ip_dhcp 'setenv autoload no; dhcp; echo; echo ** net_dhcp_c = 1 --> Getting IP Settings by DHCP'
to
fw_setenv net_set_c_ip_dhcp 'setenv autoload no; dhcp; echo; echo ** net_dhcp_c = 1 --> Getting IP Settings by DHCP'

Next Step (Done!) : modify the tftp command to nfs command ==> so i can run all the things with just a dhcp and a nfs server and no more needing a tftp server...
Next Step 2: use nfsv4 for the root filesystem... This one should be to difficult/impossible (dracut-network package????)

Hi !

The file gpxelinux.0 is NOT necessary here. It only appears in my output because I have network boot enabled on my network for x86/64 computers. As the Dockstar initiates its DHCP request during the boot sequence, it also receives from my DHCP server the boot server and file (DHCP options 66 & 67) for x86/64 machines, and tries, unsuccessfully, to boot from it.... which is useless for the dockstar. That's the reason I've foreseen to statically define the boot file name for the dockstar instead of getting it from the DHCP server.

The problem you encounter with the file 'CA807.img' come from the fact that your dockstar gets this filename as bootfile by DHCP. Many ISPs return a TFTP boot server and file names that are bogus... Hence the need to disable DHCP if it's the case. (See the last comment in my initial post).

I wasn't aware about the autoload command. It might be usefull to check if it doesn't break the rescue system loading if the dockstar is unable to foot by TFTP/NFS. From the OpenWRT wiki, it seems to only affect the behavior of the DHCP boot :

Quote
OpenWR Wiki
autoload - if set to no (or any string beginning with 'n'), the rarpb, bootp or dhcp commands will perform only a configuration lookup from the BOOTP / DHCP server, but not try to load any image using TFTP.

I've adapted my first post to deactivate the autoload. I removed the output related by gpxelinux.0: the dockstar doesn't try to load it anymore thanks to the autoload command set to no.

Could you describe the changes you made to boot by NFS without a TFTP server ?



Edited 1 time(s). Last edit at 06/16/2013 06:28AM by tsunulukai.

To made it boot from nfs without tftp, just changed :

fw_setenv net_boot 'tftp 0x800000 $net_tftp_kernel; echo; echo ** Kernel Boot Arguments: $bootargs; echo;if tftp 0xe00000 $net_tftp_initrd; then bootm 0x800000 0xe00000;else bootm 0x800000;fi'

to

fw_setenv net_boot 'nfs 0x800000 $net_nfs_server:$net_nfs_path/boot/$net_tftp_kernel; echo; echo ** Kernel Boot Arguments: $bootargs; echo;if nfs 0xe00000 $net_nfs_server:$net_nfs_path/boot/$net_tftp_initrd; then bootm 0x800000 0xe00000;else bootm 0x800000;fi'

I consider that uImage and uInitrd are present in the /boot directory (like a normal install).
Every thing is fine with nfs (v3)!

Booting from nfs4 is not possible uBoot seems to not be able to do that (using nfsv3 naming works).
Mounting / on a nfs4 partition is not possible (well , i'm trying to do this with dracut-network package but i does not work and i 'm sure i have a message from the kernel but i have no serial connection so i'm stuck a this step for nfs4)

How did you do do select nfs v3 on uBoot side? Regarding "using nfsv3 naming", does it mean there is certain naming convention in uBoot envs that you used to make it v3 only?

Update - found the answer: nfsroot parameter can have options, so it seems to take

nfsroot=$net_nfs_server:$net_nfs_path,v3

@tsunulukai,

Thanks for a very well written guide! and most of all the inspiration. I'm playing with this and I have learned some new and very useful subjects.

This did not seems to be able to force the nfs share to mount as v3.

it should be :
nfsroot=$net_nfs_server:$net_nfs_path,vers=3

but when i talk about nfsv4 vs nfsv3 notation i mean :
if /export is the nfsv4 export (option fsid=0) then you can have another export into /export, say /export/dockroot and dockroot is a mount --bind of a directory elsewhere then if you write:

nfsroot=$net_nfs_server:/ <==nfsv4
nfsroot=$net_nfs_server:/export <== nfsv3 or <

and (what we want)

nfsroot=$net_nfs_server:/dockroot <==nfsv4 (but it does not work even with dracut-network, the classic nonody:nobody problem is occuring when trying to mount at boot)
nfsroot=$net_nfs_server:/export/dockroot <== nfsv3 or <

you can lso force nfs server to v3...

qdftowner,

Thanks for the info. But strange, "vers=3" did not work for me, the kernel rejected it as an option in the command line. I'm running 3.8.11. When I use v3, it was accepted.

run fine also with debian jessie (stock kernel 3.9.6.1 from a fresh debootstrap)!
going to test if more success with nfsv4 ...

Forcing NFS version 3 for nfsroot did not seem to work for me. I'm running kernel 3.9.11.

In this bootargs I tried to set to version 3:

nfs_set_bootargs=setenv bootargs console=$console root=/dev/nfs nfsroot=$nfs_server:$nfs_path,vers=3 rootfstype=nfs rootwait  ip=$nfs_ipconfig $mtdparts

UPDATE:
Perhaps the syntax has changed, I tried nfsroot=$nfs_server:$nfs_path,v3 before, and it seems to take. But I also had other problem with "protocol not supported" error so I thought that this option did not work. But now that my other problem was solved, I left the v3 option in, and everything works as intended.

So my bootargs currently is

nfs_set_bootargs=setenv bootargs console=$console root=/dev/nfs nfsroot=$nfs_server:$nfs_path,v3 rootfstype=nfs rootwait  ip=$nfs_ipconfig $mtdparts

Thanks tsunulukai and qdftowner for the info.

Hi, i updated the envs a bit for use with my PogoPlug Mobile. Works great. It's using NFS only, no TFTP.

I added DTB-support also.

You'll have to edit your bootcmd aswall. Just add "net_bootcmd;" before reset in the end...

fw_setenv bootcmd 'run bootcmd_mmc; run bootcmd_usb; run bootcmd_sata; net_bootcmd; reset'

> Note i'm using NFS v3 + TCP.

Yes. Booting with NFS v3 has been working well for me for a couple of years. NFS v4 had some problem. I have not tried to change it, so don't know the current status for NFS v4 booting.

Haven't tried v4 either. By default it will use v3, even if you don't specify it.
By default (comes with the new kernel) the rootfs will be mounted as read-only, so you'll need to add "rw" to "net_set_bootargs" as i did. Wasn't needed earlier.

Anyways i'm happy with my NFS-setup...
My PogoPlug V4 with a 2.5"-drive is exporting the rootfs for my (now medialess) PogoPlug Mobile...
Writespeed to disk (export = sync) is 13,5mb/s. The only concern is the cpu/memory usage of the server under load, but it seems to work ok.

JohnW,

But you have to export the NFS share as V3 by using the V3 syntax.

Strange, which NFS version you're running? I don't need to do this. Perhaps it has something to do with your specific export.

Perhaps I can help if you can describe what is abnormal, my Pogo E02 running as normal as other plugs, nothing unusual.

Hi Bodhi,

I tested without the v3-syntax and it worked anyway. Theres no change in the output of "mount" if you add it, i choosed to include it anyway.

Mount gave me:

10.0.0.22:/srv/nfs/hosts/pp02 on / type nfs (rw,relatime,vers=3,rsize=16384,wsize=16384,namlen=255,hard,nolock,proto=tcp,port=2049,timeo=7,retrans=3,sec=sys,local_lock=all,addr=10.0.0.22)

My export is so standard as it can be. I haven't specified NFS-version anywhere.

Heres my fstab on the client.

root@pp02:~# cat /etc/fstab
# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
/dev/root      /               nfs     noatime,errors=remount-ro 0 1
tmpfs          /tmp            tmpfs   defaults          0       0
10.0.0.22:/exports/music /media/music nfs ro,async,hard,intr 0 0

(Will change the second to sync, tcp so they all are the same).

The wierd thing is that my secondary NFS-share (for MPD) doesn't get mounted at boot. No error-messages at all.
Tried to add _netdev etc, hoping it would have an effect.
Maybe a bit offtopic...

Full mount output, minus tmpfs-mounts.

10.0.0.22:/srv/nfs/hosts/pp02 on / type nfs (rw,relatime,vers=3,rsize=16384,wsize=16384,namlen=255,hard,nolock,proto=tcp,port=2049,timeo=7,retrans=3,sec=sys,local_lock=all,addr=10.0.0.22)
rpc_pipefs on /run/rpc_pipefs type rpc_pipefs (rw,relatime)
10.0.0.22:/exports/music on /media/music type nfs (ro,relatime,vers=3,rsize=16384,wsize=16384,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=10.0.0.22,mountvers=3,mountport=56581,mountproto=udp,local_lock=none,addr=10.0.0.22)

Any ideas? I asume it has have something related to the primary NFS-rootfs existing...
"mount /media/music" mounts it w/o problems...

Regarding the performance-issues, it's not a big deal. It's just that when i run "apt-get update/upgrade" etc. on the clients the CPU hits 100% continuously. Memory goes up to 20MB free an swap is used.

No big deal, under normal operations the NFS-clients don't do any heavy disk-related stuff (if non at all!)...

/John :-)

John,

> My export is so standard as it can be. I haven't
> specified NFS-version anywhere.

It does imply different version with the syntax. So if it's vanilla then the syntax imply v3. But if you use something specific like fsid in the parameter then it's exported as v4 (if you do have nfs v4 in the kernel).

> "mount /media/music" mounts it w/o problems...

You can mount it in /etc/rc.local. I think it is too early because the rootfs itself has not been mounted completely yet.

Yes you're absolutely right, i did read about it earlier - don't know why didn't think of it now, doh... Even qdftowner wrote about it above...

Yes, i'm not fully aware of how and at which time the lines in fstab are processed - but you're probably right about it.

Bodhi, with systemvinit i had to add "mount -a -t nfs4" to rc.local to have the second nfs-share mounted at boot.

With systemd i did not need to do that. My idea is that systemd is a bit more intelligent when it comes to pick the moment when to run stuff... Case closed.

Nice. When I get sometimes, I will definitely peruse this thread and use my DockStar as a test bed. Thank you all.

Thanks so much tsunulukai!
I had a usb drive enclosure die and my dockstar has become so integral to my everything here. I had a couple of spares, one doesn't work at all on the dockstar, the other works fine from cold boot but upon reboot it can't be seen (the infamous Super Top m6116 chip, try not to get one). Yes I tried usb stop-sleep-start, etc., nothing worked. But this did, and it was so easy with the code already done! Once booted into say, rescue, the disk was seen just fine, I only had to get past the kernel booting, so this was ideal, I only have to tftp the zImage/dtb. And my tomato router has dnsmasq, it has tftp built in, just use the routers usb stick for storage.
I've fooled around with tftp before, always disappointed, but this was easy. Wow, can't tell you how thrilled I am to be able to reboot, my dockstar is kept in a somewhat inaccessible place, quite the effort to get to, so getting up and doing that to pull the plug every time I needed to reboot didn't thrill me. Now I can take my time getting a good replacement enclosure.
So much good stuff at Jeff Doozan's place...

I've forgot all about this. But since this thread is active again :) FWIW.

Regarding mounting NFS shares in sysvinit. Here is a way to specify in whether NFS share should be mounted asynchroneously, or wait until the NFS rootfs was mounted.

Add this in /etc/default/rcS

ASYNCMOUNTNFS=no

Hi there !

First of all, many thanks for your positive feedback :)

Just a quick update for those of you who run debian as their NFS server to boot their dockstar. When updating to Debian 9 Stretch, the nfs-kernel-server packages disables NFSv2 by default. This broke my NFS setup with the dockstars, which, although configured to use NFSv3, seems to initialize their boot using NFSv2. (It might be due to the kernel version I'm running)

I could confirm this in wireshark:

Remote Procedure Call, Type:Reply XID:0x00000004
    XID: 0x00000004 (4)

To re-enable NFSv2 in Debian 9 Stretch, you just need to add the following lines to /etc/default/nfs-kernel-server:

# Enable NFSv2
RPCNFSDOPTS="-V 2"

Hope this helps :)

If I might add further explanation. The reason was older u-boots only has NFS v2 :) So the nfs-kernel-server detects that and provide NFS v2 protocol. Even though we export the rootfs share as v3.

u-boot did not have NFS V3 until recently. So when I release the new kirkwood u-boot-2017.05. This problem will be solved by itself. In the mean time, thanks for this hints! people are likely to run in to this problem after upgrading to stretch.

Hello there !

I finally updated my Dockstars to uBoot 2017-07 by bodhi, so I thought I might as well provide you with the updated procedure to NFS boot. It concerns the section #7 of my initial guide, which should be replaced with the following after having update to the latest uBoot and reset the uboot environment to uboot.2016.05-tld-1.environment.bodhi.tar. This update also only relies on NFS to complete the boot sequence, completely bypassing TFTP as suggested by JohnW. It also supports using DTB using the variable net_nfs_dtb. The network boot commands mimics the new boot commands delivered by bodhi.

I've tried to align the syntax on bodhi's one.



7. Create NetBoot variables in uboot on the Dockstar from the running Linux:
This will not yet alter the Dockstar startup configuration. All the following commands create non-existing variables into uBoot, assuming you're using the stock uboot.2016.05-tld-1.environment.bodhi uboot env.

# Fix DTB load address for Debian Buster Kernel
fw_setenv load_dtb_addr 0x02000000

Reboot the dockstar, interrupt the autoboot and execute

run net_bootcmd

If booting succeeds, the you may override the default bootcmd with

fw_setenv bootcmd 'run net_bootcmd'

Unlike my initial guide, which would first try to boot from the network, and failover to usb drive, this config will only attempt to boot from the network.
Should you need to restore the initial boot behavior, just restore the original bootcmd with

fw_setenv bootcmd 'run bootcmd_uenv; run scan_disk; run set_bootargs; run bootcmd_exec'

As before, you can check the boot process using the serial or network console.
