Kernel panic - not syncing: VFS

@George-Lebay change pxelinux.0

@George-Lebay said in Kernel panic - not syncing: VFS:
For what it’s worth, in the ltsp.conf file, the boot filename line is set to : dhcp-boot=pxelinux.0
OK this answers the questions, specifically.
(I was going to go the easy route, but lets do it right way).
In the ltsp.conf file change pxelinux.0 to undionly.kpxe and save the settings.
Then in /tftpboot create a symbolic link from undionly.kpxe to undionly.kpxe.0 (the number zero). You would use a command lineln -s /tftpboot/undionly.kpxe /tftpbppt/undionly.kpxe.0
Restart dnsmasq.
PXE boot your client.This way when you update FOG and the undionly.kpxe file gets updated, dnsmasq will always have the latest file. You could have just copied undionly.kpxe to undionly.kpxe.0 but at some time when you update fog, these files will get out of sync.

@george1421 First, thanks a lot for your help. Unfortunately I get the same error.
The Fog menu appears correctly on the client, but then whatever option I choose I get the Kernel Panic message …
-
@George-Lebay Did you remember to restart the dnsmasq service? If yes then…
Is the fog server and the target computer in the same subnet/vlan? If so we’ll need to get a packet capture of the booting process to see what’s going on with the client.

@george1421 I have decided to reinstall 14.04 server from scratch and fog 1.2.0 with the latest kernel. I need to start a new thread. Thanks again for your help.
-
@George-Lebay Why not go with FOG 1.3.0-rc4? Any reason since you are doing a clean install anyway? Just install the rc version https://wiki.fogproject.org/wiki/index.php/Upgrade_to_trunk

@george1421 Well I had this old Proliant ML150 G6 doing nothing and I wanted to use it as my next Fog server. Since Fog is not operational at the moment, and it’s pretty quiet around here (I work in a university) I decided to make the hardware switch.
About the problem I have now, which is the same problem I had at the very beginning:
I have 2 models of client PC. HP 6200 and HP Prodesk 600 (that I just received).
Fog works perfectly well with the 6200, but I when try to register a Prodesk 600, I’m getting this error: Unable to register host for the following reasons:
Then it gives no reason, and then the system displays some inventory data. Then it just slowly scrolls down forever after it displayed the message attempting to register host …I tried to upgrade the kernel, then it just got worst. It did not work on either the 6200 or the ProDesk 600… I was getting this message on both models:
Unable to register host: Invalid MAC Address! (/bin/fog.man.reg) -
@George-Lebay Right, with FOG 1.2.0 the max kernel version you can use is < 4.4. So in your case try 4.1.2 and see if that works with the Prodesk 600. If not you will need to upgrade to 1.3.0.rc4. Since this is not a production server (yet) then there is no harm in upgrading. (Yeah I know I’m pushing, but the new features in 1.3.0 are worth the extra effort to upgrade).
-
@george1421 I will make the upgrade to 1.3.0. My fear was to get that Kernel Panic message again (Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,0)) but since I’m working with fresh server and FOG installations, I’ll give it another try. I’ll let you know what happens then.
-
@George-Lebay Are you running dnsmasq?
But if you upgrade then you have a better chance of getting support since you are on a supported OS and active version of FOG.
-
@george1421 It works ! Thanks for your support
edit : Yes I’m running dnsmasq.
