Deployment stuck in a loop, never finishes imaging?
-
@salted_cashews yes. it’s the minimal Linux OS that loads over the network to do the imaging tasks
-
@Junkhacker Thanks for the info!

@salted_cashews FOS is the Fog Operating System that runs on the target computer. It is linux based and is built from bzImage (kernel) and init.xz (virtual HD) .
If you run a debug capture/deployment you can access this log file. It only exists on the virtual ram drive that FOS uses.
-
@george1421 This is really interesting, is this why I’m able to almost-ssh into the box during an image/network boot?
-
@salted_cashews Yes. It IS an operating linux OS. If you boot into debug mode and then give root a password you can ssh into the box as root and run the debug deployment/capture remotely. I use this method when debugging/developing post install scripts.
-
@salted_cashews Are you sure the image was captured with Zstd as well? If you change that option in the image setting you need to re-capture it!
Running a debug deploy task and ssh into it (you need to set a root password within the booted FOS environment on your client machine using
passwdcommand) to look at the partclone.log is definitely a good idea. -
@Sebastian-Roth I’m 100% positive it was captured using Zstd, the only thing I can think of is something we did on the image before capture or a network issue during.
-
@salted_cashews See if you can grad the partclone.log file and hope we get some more information from that.
-
@salted_cashews I find it really strange that the filesystem does not seem to be clean. Are you sure the filesystem was clean when you initially captured the image? Sure the machine was not in some kind of hibernation when it was PXE booted to be captured?
-
@Sebastian-Roth Indeed, the image was a CentOS 7 image that had been rebooted (hibernation on the OS is disabled via the GUI). This had happened with one other image as well, and I remember us running some basic “clean up” tasks beforehand. It’s possible these mucked up the file system or something. Let me see if I can trace back exactly what we did.

Maybe
.bash_history…? -
@Sebastian-Roth To my dismay the host was just “nuked” this morning. On the bright side I’m testing another deploy debug and I’m SSHd into the guy. Is it possible to have the root password set via
passwdby default on a deploy/capture? I’d love to just be able to jump in like this at-will. -
@salted_cashews Take a look at Tom’s post here: https://forums.fogproject.org/post/88286
Though I have not tested this myself lately it should still work I reckon.

@Sebastian-Roth Thank you sir, as far as the logs are concerned this is what they report:

@salted_cashews Please run the following command on your FOG server:

@salted_cashews Possibly this version of
filedoes not detect Zstd compressed files. Please try to manually extract the image to see if that works properly:zstdmt -d /images/PPS_v9.0R2-dev_CentOS/d1p3.img -o /images/PPS_v9.0R2-dev_CentOS/d1p3_extracted.datSee if that triggers an error or not.
Hint: You might need to install package
zsdton your FOG server. -
