Imaging Jobs Freezing

[sudburr]

Try taking the NCR device and any other non Gb device off the network then try again.

Are you able to isolate the FOG server to it’s own subnet/vlan and work within it with purely Gb devices?

[atarone]

@sudburr I tried that before starting this thread as I thought I was having a network problem. The FOG server already resides in its own vlan, we setup it up that way on day one.

Thanks,

And if you put a target computer on the same vlan on the same switch does it freeze?

@george1421 I thought it was my environment before I opened this forum topic. To this point I have tried the following without any success:

1.) Image different targets(different PC, Different image)
2.) Removing the bond interface on server and using single GbE
3.) Putting target on same switch as Server
4.) Used completely different switch
5.) Removing non-GbE devices

I am not opposed to standing up a totally new server and testing, but it will take some time. This worked without any issue until this past Tuesday. We updated to FOG 1.4.0 in late May or early June and we were imaging everything without issue. Then we got the issue we updated Linux and tested, then updated to FOG 1.4.2 and tested. As a side note, may have nothing to do with this, my server is still saying I am not running the latest version of FOG. I know there was a forum post that addressed that issue, but just thought I would throw it out there.

Thanks,

Anthony

@george1421 Yes. All imaging is done is the same vlan. So the target and server are on the same vlan.

[george1421]

@atarone Well I really think we are at the point I call divide and concur. We’ve tested about all I can think of with this current setup. Spinning up a new fog server on a desktop (if you don’t have the hardware) would be the next steps. Place the new fog server on a dedicated switch (unmanaged will do) plug the unmanaged switch into your business switch and a target computer into the unmanaged switch. See if that setup will image correctly. If that works then attempt to image a computer across your campus (again with the test FOG server). For the sake of this testing just capture a new image to this new fog server. It doesn’t have to actually run on the target. Our goal here is to get the image deployed completely. If that works then use a known image and deploy that. We are at the point were we may have to go with a greenfield approach to finding the root of the issue.

@george1421 I will get a lab environment setup and report back what I find. Just for the sake of argument I did perform a capture task with the NCR with the all of the normal settings and the capture task was successful.

Thanks,

Anthony

@george1421 I tried re-installing FOG without any success. I have a lab environment at home so I will re-create and test there. The only difference will be that the FOG server will be a VM instead of physical. I will report later next week what I find.

Thanks,

Anthony

@Tom-Elliott
I setup a FOG server in a test environment. Different switch, different server,etc and the imaging jobs are still freezing and locking up. What could be causing the client to lockup?

Thanks,

@atarone Reading all the things you have already tried I think we need to tackle this from a different angle to get a step forward. So I modified the most current init.xz image to spawn a second virtual terminal. Usually FOS does not spawn a second one because there is no need to. In this case I thought this might be helpful for the first time.

On your test FOG server, download init.xz here and put it in /var/www/fog/service/ipxe (move the original out of the way).

Then schedule a deploy task for your test client and boot it up. It should boot just as it used to and while FOG sets things up for imaging you should be able to switch between virtual terminal one and two with the well known keys Ctrl+Alt+F2 and Ctrl+Alt+F1… On the second terminal hit ENTER once and you get to a shell. Here you are free to run commands while FOG is doing it’s thing on VT1.

I’d start with getting VT2 ready but then switching back to VT1 and watching partclone. After freezing, are you still able to switch back to VT2? If yes, what do you see when running dmesg for example? If you cannot switch back to VT2 then … (I am still thinking about what to do next then!).

Really nice, we could have used that for the switch console test, to see if the target was freezing or just the session was hanging. Thanks!!

@Sebastian-Roth
@george1421 So I updated init.xz with the one created by Sebastian-Roth and now images deploy, but Windows no longer boots after imaging. So i did a capture job thinking that the image is just messed. It did the capture but returned errors trying to update the database using the username “fog”. I tested that login and it is still the default. What password is it trying to use and could this be the root cause of my deployments freezing?

Thanks,

Anthony

This all sounds totally weird! Is this in your small simple test environment? The only thing I did was downloading the most current init.xz and adding this one line to /etc/inititab:

tty2::askfirst:-/bin/bash

From my point of view it’s impossible that this change is actually solving your freezing problem!

but Windows no longer boots after imaging.

Which error do you see? Please post a picture!

Check this wiki page about database password. Again I highly doubt that this could cause the freezing!

@Sebastian-Roth
@george1421

This has been the weirdest issue since day one haha. This is all being done in the production environment. I got the password stuff sorted out. Below is what the target is doing. This occurs anytime FOG turns over booting to the OS.

[Sebastian Roth]

@atarone I am not really sure where this is taking us. Would you mind testing with the provided init.xz file (second virtual terminal) over and over till you run into the freezing issue again. Then see if you can still switch terminals. If freezes don’t occur anymore then you might want to go back to the init.xz you had before and try again. Maybe there was something screwed with that initrd you had. Would be good to rule that out.

I am not sure about your other issue. Looks like deploy is not properly working. Is this a complete new image your uploaded freshly? Could you please run a debug deploy task on this client again (like when you schedule a normal deploy but tick the checkbox for debug). When you get to the shell run fdisk -l /dev/sda and post a clear picture of that here.

[atarone]

@Sebastian-Roth Below is the screenshots from the fdisk -l

I will be running the tests shortly with old init.xz and will get back to you.

Thanks,

Anthony

[Sebastian Roth]

@atarone So the partition table on sda (first HD) looks pretty straight forward. I don’t think there is much that can go wrong. Why did you run fdisk -l /dev/sda1? Just out of curiosity or by intention? There shouldn’t be a partition table within the first partition I reckon. But maybe that’s just a coincidence?!

Can you please post a picture (or text output) when running the following commands on your FOG server:

ls -al /images/Vertix
cat /images/Vertix/d1.partitions
cat /images/Vertix/d1.minimum.partitions
cat /images/Vertix/d1.fixed_size_partitions

[atarone]

@Sebastian-Roth The deployments started freezing again with the new init.xz and the old one.

Below are the screen captures you requested:

I think I have found part of it given this output. Please let me know.

Are you able to switch between virtual terminal one and two (as described earlier) when deployment freezes?

The numbers in the outputs you posted look pretty ok to me. I can’t see where things are going wrong here yet.

I think I have found part of it given this output. Please let me know.

What do you mean by that?

[atarone]

@Sebastian-Roth “I think I have found part of it given this output. Please let me know.” I though that last output capture being blank may have been a problem, but you said all looks good to you. I am unable to switch between the VTYs.

Thanks,

Anthony
