Deployment stuck in a loop, never finishes imaging?

[salted_cashews]

@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.

[Sebastian Roth]

@salted_cashews See if you can grad the partclone.log file and hope we get some more information from that.

[Sebastian Roth]

@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?

[salted_cashews]

@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 passwd by 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: file /images/PPS_v9.0R2-dev_CentOS/d1p3.img

Post output here.

@salted_cashews Possibly this version of file does 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.dat

See if that triggers an error or not.

Hint: You might need to install package zsdt on your FOG server.

[Sebastian Roth]

@salted_cashews Make sure you have enough space on your disk: df -h

Now as a test, please do the same with another image file:

zstdmt -d /images/PPS_v9.0R2-dev_CentOS/d1p1.img -o /images/PPS_v9.0R2-dev_CentOS/d1p1_extracted.dat

From my point of view the manual extraction test should give you an error if the image file is fine.

@Sebastian-Roth

No error this time, the error I received running it manually is the same error that displays during the task as well (on the partclone progress screen).

@salted_cashews and @Sebastian-Roth

I believe the problem is coming from the second -d

Particularly in the naming of the image, it appears to be doing:

zstdmt -d /images/PPS_v9.0R2 Then get’s a second -d from the -dev_CentOS/d1p1.image

So it’s literally, I think, doing:

zstdmt -d ev_CentOS/d1p1.img

Does this make sense?

I think the - in the image name is causing issues parsing into the zstdmt command. The reason it doesn’t impact the Ciara_CentOS-BASEmk3 is because, likely, there is no argument for -B is it just uses it like a normal string.

Maybe we need to add some quoting to the scripting?

[salted_cashews]

@Tom-Elliott Interesting catch, would just renaming and re-associating via the Web GUI work to fix this?

[Tom Elliott]

@salted_cashews I think so, yes. Rename the image to something without a - maybe?

[salted_cashews]

@Tom-Elliott Renamed, giving it another shot.
