Fog node - exec format error, chainloading failed

[Sebastian Roth]

@mtanigawa Ahhhhhhhhhhhh, I might have spotted it. If this is not a typo in your post (bzimage… ok) then I suppose you just have the wrong Host Kernel setting (for this particular client or in generel settings for UEFI clients). Linux is case sensitive and bzimage is not same as bzImage (the default name in FOG).

If that’s the case I was wrong with my first assumption that iPXE was able to download the kernel binary!

Thanks for your additional details.

Initially when checking into this error, I did replace the bzimage w/ a clean on from the working test server. I assume that the bzimage was again replaced when I updated from 1.5.5 to 1.5.6. It may have been my typo on the bzimage text.

I will load the corrupted backup onto a test box and see what comes out of it and check the URL posted.

Thank you.

@mtanigawa Shall we keep this issue open. Will you get to look into this over the next days?

[mtanigawa]

@Sebastian-Roth

Yes, if you wouldn’t mind please. I will prep a box tomorrow with default installs and restore the backup. Will then run through and let you know what I come up with … or if it all decides to just work.

Thank you.

i think this is the same error as mine that started yesterday and it happened after i did a apt-get upgrade… i noticed at the end of the upgrade i has these lines:

NOTICE: Not enabling PHP 7.1 FPM by default.
NOTICE: To enable PHP 7.1 FPM in Apache2 do:
NOTICE: a2enmod proxy_fcgi setenvif
NOTICE: a2enconf php7.1-fpm
NOTICE: You are seeing this message because you have apache2 package installed.

ive just switched my fog server off as its stoping the workstations to boot and i cant stay late to troubleshoot it today… but i can tomorrow…

@Gordon-Taylor ignore me… ive just reinstalled fog and mine is fine now… the mysql bug as mentioned at the begining of the thread

Hopefully this issue will be fixed in 1.5.7 or 1.5.8 where we should not have this issue moving forward, right @Developers

@Gordon-Taylor Am I on the wrong track here? I can’t see your issue being related to the one posted here in any way. Here we are very likely talking about a miss-configuration (typo in bzImage name). Did you get the exact same error message “Could not select: Exec format error”??

@george1421 @Gordon-Taylor What mysql bug are we talking about here?! Do you mean using an empty mysql root account password in FOG?

Yep, that one. We can talk about it off line.

@george1421 Can we move this discussion to another thread or even better open an issue for it so it won’t get lost in the depths of the forum??

@Sebastian-Roth

I have built a vanilla box, installed fog and restored my configuration … and it all worked! I was able to boot via pxe and uefi on the first try of each.

I will chalk this up to both the blank mysql password and a miss named bzImage file. As it is all working with the “bad” backup config, I will ask that this ticket be closed. One day, if I’m bored enough, I’ll try another restore again and see if it will fail.

Thank you for all the help! It is greatly appreciated.
