Deployment stuck in a loop, never finishes imaging?

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 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.

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.

salted_cashews

@Tom-Elliott
Here’s the result after renaming using a “_”. We have other images using “-” and “.”, would this be best practice to avoid even if they still work fine (haven’t had this issue until now)?

@salted_cashews The - ultimately shouldn’t matter in the context of the imaging process.

We pipe the image into a FIFO (First In First Out) file called /tmp/pigz, then we perform the decompression and write to disk from that filename. So no, it shouldn’t matter how the image is named. In particular, howeve,r is the fact that the image keeps saying no such file or directory called d1p3.img*. The * is in the case of “split” file formatting. (d1p3.img.001, d1p3.img.002, etc…) but should work regardless of the file as long as the file exists.

Looking through the thread, it appears each time asking for information that the file name’s are varying. I’m sure you have the files though, exact comparisons would be great.

In the case of the image named PPS_v9.0R2_dev_CentOS, You have d1p1.img and d1p2.img. So why is it failing on d1p3.img?

The scripting uses the same formatting for each image file. So when it comes to partition 1 it’s running the arg passed as /image/PPS_v9.0R2_dev_CentOS/d1p1.img* as well as d1p2.img* for partition 2. So it’s really confusing to me that it keeps failing on that same file.

Can you get us files inside of /images/PPS_v9.0R2_dev_CentOS/?

ls -lhart /images/PPS_v9.0R2_dev_CentOS/

I’m sure this is redundant and all, but just trying to get the full scope.
