Imaging Issue

If it does work, we should slowly iterate up in the revisions until we find where it breaks.
This will help the developers with creating a fix.

What’s most intriguing to me is that it doesn’t work at one level but works fine elsewhere?

That’s very interesting to me too. And yet there are other machines connected to the same switch that are working, exact same port configurations.So the latest update: I did a fresh install of Ubuntu 12.04 and fog r2961. Much to my surprise, I’m seeing the same behavior - the network is starting before the link is up, and it’s not getting an IP. “Downloading kernels and inits…OK” Is it downloading the latest and greatest kernel/init, no matter which revision I’m on? I did go into settings and revert back to a kernel from February, but same results. What does the init.xz file do, and is there a way I can get a version of that from back in February?
-
It is getting the latest kernels and init’s every time. No it’s not possible to download one from february anymore, but this is not where things are failing…directly. Nor is it the kernel if the interface comes up outside of that scope. The only thing I can think is the other Nodes/Servers you have are on older Init’s?

Okay, good to know. I’m going to try to get those files off the VM backup just to see if they make a difference.

Where is this new r2961 build located, physically? Building “A” or the troubled building “B”

[QUOTE]Where is this new r2961 build located, physically? Building “A” or the troubled building “B”[/QUOTE]
The new server is physically located in building A. All of our virtual infrastructure is there.So I do have good news - it’s working, with some recovered files. Undionly.kpxe appears to have nothing to do it. The problem appears no matter which version of that I have.
The culprits seem to be init.xz and bzImage. I restored both of them from a backup from 2 weeks ago. When those restored files are in place, everything works happily on both r2961 and r3278. As Tom pointed out earlier, it looks like the revision version of FOG does not apply to these 2 files. It’s worth noting that replacing one or the other didn’t fix the problem - I had to replace both of them for it to work.
I see one major difference in debug mode, I attached a picture for clarity. The difference is I see the sending discover. It sends one discover, then the link comes up, another discover, and bingo - it gets an IP. That sending discover process does not show up in the bzImage/init.xz file combination that the installer script is currently downloading.

Ok now we’re getting somewhere, good job! It’s not your network after all.
From here, it’s up to Tom.
I’d recommend making a copy of those two files and put them in a safe spot for the future…

While on that prompt, what’s the output of uname -rm?
-
Yep! - finally making progress haha
uname -rm returns this: 3.18.5 x86_64
-
That number seems… familiar.

From a previous post:
[quote=“sudburr, post: 44203, member: 4706”]I rolled the kernel back through successive older versions.
– svn: 3127
[B]-- Kernel: 3.18.5[/B]
– iPXE: 1.0.0+ (acc27)[FONT=Tahoma][COLOR=#141414]… works.[/COLOR][/FONT][/quote]
[FONT=Tahoma][COLOR=#141414]Just tying these two things together because there’s clearly an issue.[/COLOR][/FONT]

I’d like to try them.

Sure, these are the files currently working for me:
bzImage: [url]https://www.dropbox.com/s/m9ti2dieab1eqn9/bzImage?dl=0[/url]
init.xz: [url]https://www.dropbox.com/s/r3lsc4301h58jwx/init.xz?dl=0[/url] -
[FONT=arial][COLOR=#222222]Can you try 3.19.2, and then set the USB nic flag and see if it works?
If that does, can you do the same with the next till we find where things go wrong?
This was Tom’s idea, btw.[/COLOR][/FONT] -
Hmmm… you lost me there. Or I’m having a brain moment. How do I set the USB nic flag?
-
On a host under kernel args add has_usb_nic=1
-
Finally got a chance to get back to this!
Setting the usb nic flag doesn’t make a difference.
