Kernel Panic - Not Syncing(Lenovo ThinkPad Edge)

[T3charmy]

I’m having a bit of an issue with fog. Everything worked fine on our older fog server that ran 0.32 but the hardware was so outdated it needed to be replaced. We setup a newer machine with Ubuntu 14.04 and Fog 1.1.0(1801) and are having kernel panic issues with our ThinkPad laptops. I’ve tried various kernels both official and up offical(if I remember correctly the one in picture is 3.15.0 by Tom Elliott)

Is it possible that the kernel and init are for different architectures? It looks similar to [URL=‘http://fogproject.org/forum/threads/problems-inventorying-a-hp-450g1-with-0-33b.10157/’]this forum post[/URL].

It shouldn’t be I specifically double checked that…

[T3charmy]

Just to double check, when I got in the office this morning I downloaded latest official kernel this is what I got:

The “Official” kernels which one?

Did you do 3.14.2 64bit or 3.14.2 32bit?

Looks like you may have some bad ram on your system then man, based on the output of the “inode” references.

You can verify this by trying another system of the same make and model.

[T3charmy]

Same exact error on another laptop. trying on a laptop that we already imaged with the 0.32 server

Edit: Same issue on that laptop too… Is it possible the memory in the server being bad cause this issue?

[Tom Elliott]

Looks like you may need to take a stab at building a kernel.

The messages you’re being presented with are saying that the init that’s loaded into RAM is not working. Do other systems work fine?

If they do, then chances are likely you have a corrupt init.xz/init_32.xz file, however if everything loads fine, then those systems are placing the file in a strange place in ram. I don’t know what else to say.

[Tom Elliott]

Sorry, my post didn’t see your post until after a refresh reread.

It’s not likely the server RAM is bad, but that the location the file is at on the server, maybe the disk is going BAD?

So the volume containing /var/www/fog/service/ipxe could be bad?

What would cause it to work with the old version but not 1.1.0? I’ll try on a different system we have here… Do you have any wikis or anything to assist with building the kernel? I’ve used linux for years… but never really have built a kernel…

It sounds like one of the disks in the server are going bad and not sending the init properly as you’re saying it’s happening on multiple systems.

Try redownloading the init.xz and init_32.xz to your fog server, if all is well things should start working again, if the disk is bad, chances are you’ll continue to see the problem.

[code]sudo mv /var/www/fog/service/ipxe/init{,_32}.xz /var/www/fog/service/ipxe/init{,_32}BAD.xz
sudo wget -O /var/www/fog/service/ipxe/init.xz https://svn.code.sf.net/p/freeghost/code/trunk/packages/web/service/ipxe/init.xz
sudo wget -O /var/www/fog/service/ipxe/init_32.xz https://svn.code.sf.net/p/freeghost/code/trunk/packages/web/service/ipxe/init_32.xz
[/code] Retry, hopefully all starts working again.

Other’s check if the hard drive is bad.

I tried on another machine I got same error too. so init.xz/init_32.xz files could be corrupt? where can I get a copy of these files? If I need to… I can try another harddrive in the server and see if that helps…

Hey! That worked. Looks like it was a corrupt init.xz file! Thanks for all the help! Now just have one small issue I gotta fix(forgot to set the operating system type in image).

[T3charmy]

[url]http://i61.tinypic.com/2m2j7yd.jpg[/url] Now we can get back to imaging these other 30 of 60 laptops!

[Tom Elliott]

Nice man, best of luck.

[T3charmy]

Or not… Got the first 20% of the image downloaded to the laptop and then it just rebooted out of no where saying the job was completed. Now we’re having the same old issue that we used to have back on 0.32(Unable to locate image store).

[Tom Elliott]

That’s quite possible that the storage location that’s containing the images are corrupt, or the files that “are” the images are corrupt.

[T3charmy]

Hm. Alright. We had this issue quite a lot on our old server which is one of the reasons we moved to new server … I guess worse case scenario we have to grab one the other laptops and remove it from the domain and reupload the image to server to see if that fixes is… Not sure that the hard drive on the new server is corrupt, but then again it is about 6 years old …
