Unable to deploy Snapins - Stuck in Que

[Avaryan]

I had a similar issue occur a few days ago. I had someone use an image (ahead of schedule) as I was still uploading a new version.

All of his hosts received the older image, which was fine, but snapins wouldn’t deploy. The client renamed and joined the domain, just no snapins.

I ended up pushing out a simple PowerShell script to toggle the FOG service off and on again, then everything started working properly.

So I checked the error.log file at /var/log/apache2/error.log and I get this:

Can you upgrade your version of FOG to see if this has already been addressed?

[tyler2017]

@Tom-Elliott Recommended version to upgrade to?

[Tom Elliott]

@tyler2017 Latest, 1.4.4.

[tyler2017]

@Tom-Elliott I’ve never done an update before, only fresh installs. Do I just need to run the installer for the new version? Stupid question, I know. Just checking… I’ll definitely back things up first.

[Tom Elliott]

@tyler2017 Upgrades are automatically handled by the installer yes. You just re-run the installer and it will update the things it needs to update.

[tyler2017]

@Tom-Elliott Now all of my clients are showing this:

I am unable to find any duplicate MAC address for any hosts. Any ideas?

@tyler2017 So the “Error multiple hosts returned for list of mac addresses” means there’s likely a duplicate MAC Address being passed, but what you’re looking at for “mac addresses” is not the same as the list the client is passing.

I’m not saying you did anything wrong and I hope I just corrected some of the checking code.

Would you mind trying:

wget -O /var/www/fog/lib/fog/hostmanager.class.php https://raw.githubusercontent.com/FOGProject/fogproject/57d36f5ce22b960db99ad290f1d20b7be1c93e37/packages/web/lib/fog/hostmanager.class.php

# Ensure /var/www/html/fog has updated file just in case /var/www/fog is not already linked appropriately.
wget -O /var/www/html/fog/lib/fog/hostmanager.class.php https://raw.githubusercontent.com/FOGProject/fogproject/57d36f5ce22b960db99ad290f1d20b7be1c93e37/packages/web/lib/fog/hostmanager.class.php

“A valid database connection could not be made”

Of note, for this error above, it seems possible that DB is full, or not running properly? (Maybe a whole ton of data causing a delay getting the information.)

I’m only guessing based on what I see. This is, for the most part, unrelated to the “Multiple errors exist” thought it’s not impossible a Full/Corrupt DB would be sending a ton more information than expected causing the error to throw. (So DB issues could send lots of excess data in the query, but this would only happen if the DB instance was still running.)

[tyler2017]

@Tom-Elliott I tried the commands you suggested. I’ve not noticed any changes in anything. The fog.log on all clients is still showing the same thing. Still unable to push snapins…

[Tom Elliott]

@tyler2017 Do you mean you’re getting the Invalid database error still?

[tyler2017]

This post is deleted!

[tyler2017]

@Tom-Elliott I no longer see the database connection error, but I do still get these…

Mind running an SQL query on the db with:

USE fog;
SELECT hmHostID,hmMAC FROM hostMAC WHERE hmMAC IN ('1A:E3:47:B3:65:43','28:E3:47:B3:7C:B3','28:E3:47:B3:65:43','00:09:0F:FE:00:01','A0:1D:48:B0:29:CC');

[tyler2017]

@Tom-Elliott Pardon my ignorance, but how would I go about doing that?

[tyler2017]

@Tom-Elliott

Nevermind, I figured it out… I think.

[Tom Elliott]

@tyler2017 So you might add a filter for a0:1d:48:b0:29:cc.
