Kernel Update and different Hardware

could you be more specefic, what do you mean by Host Kernel?
I don’t see any Host kernek under Fog settings if that’s where I should look
Thanks -

Winscp can’t edit permission on tftpboot folder, It gets permission denied
Looks like my only luck is updating kernel through kernel update in Fog which is limited to only existing Kernels.
Thanks -
something that I just did.
I logged into ubunto, my fog server, and tried to read the permission on the tftpboot folder.
it shows that Fog is the owner and doesn’t let me do anything -

sudo cp /media/C810-83C8/bzImage /tftpboot/fog/kernel/bzImage
/media/C810-83C8/bzImage <-- Being my flash drive and /tftpboot/fog/kernel/bzImage <-- Being the location where kernel needs to go.

Here is what I did:
Since I could not get ubunto to see my USB drive that was attached to ESX host, I downloaded the Kernel from your link and then used the sudo cp command to copy it over to existing kernel.
I tested 4 of our Dell machines, Dell E6410, E6420, Dell 760 and Dell 780, with success.
I should say I did system compatiblity test in system information from PXEBott Menu and they all passed.the only problem I have is the with Dell 780 which is stuck in uploading the image eventhough I removed it from hosts list on Fog server , it still upload the image to Fog no matter what.
I need to figure out where it’s Mac address has got stuck I think.
Thanks for the working Kernel you sent, you are awesome.
Thanks again -
I was right, the mac address of that machine was in the following folder:
/tftpboot/pxelinux.cfg , which I was able to delete by using the command: sudo rm { Mac Address} -
On the general tab for any host there is an option to point to a different kernel. Find a host, then look in general options and point to different kernel thats stored in your fog server.
Look at the properties for any host you will see the Host Kernel field.

Anyone have any luck with Dell Poweredge Servers? I compiled my own kernel 3 times now to include the RAID drivers yet it still seems to not accept it.
Specifically LSI RAID Drivers.
Dell Poweredge 1850,1950, 2850,2950 are the ones I have attempted and failed.::FOG CANNOT IMAGE SERVERS:: until proven otherwise.

Joshua, try looking for the article about installing Linux on the PowerEdge 2650 server, which has a PERC4 raid controller. It may lead you to the answer eventually, I hope.
Sid, the custom kernel options are per HOST, or per GROUP and ONLY apply to tasks created for the host or group through the Web UI. If you boot to the fog menu and choose any of those options, it ignores your kernel settings for the host because the kernel to use is hard-coded into the menu file.
To clarify: If you can register and inventory with the default kernel (bzImage), you are good to specify a different kernel or kernel parameters for upload/download tasks. If you can’t register or inventory some machines with the default kernel, you’ll need to kernel swap or compile a custom kernel.
Being a long time Linux user but new to kernel compiling, I took this challenge a few months ago and documented it well on the old forums and copied it to the new forums.

[quote=“Eric, post: 2657, member: 83”]I recently made my own Kernel as a proof of concept. Its based of the Linux 3.3 Kernel and it resolved a lot of problems for me. Its attached in my post here. Be sure to backup any of your existing Kernels in /tftpboot/fog/kernel/
Let me know if it works for you.

Thanks for sharing, Eric. Works like a charm on all the problem Dells we had (760, 755, 740, GX620). Much appreciated

This kernel worked for me. Thank yo so much eric. I made it the default kernel and my new machines and old machines boot.

[quote=“sid, post: 2680, member: 558”]Thanks for the kernel, but I keep getting permission denied when I try to copy it to tftpboot/fog/kernel folder.
I use winscp and log on to server with admin account.
any Idea?
thanks[/quote]I’m sure you’re way past this, but I use nautilus from my Ubuntu workstation to connect to my FOG and WinSCP from windows. SSH works a treat but sometimes I need a GUI.
