some global settings being cleared during group settings update



  • Ubuntu 14.0.4, Trunk SVN 7597 - just updated today

    I updated Service Settings for all machines using group update and now all of the service settings for all the machines in the group are blanked out.

    The last report of this I see was 11 months ago, has it possibly come back?



  • @Tom-Elliott - THANK YOU!!


  • Senior Developer

    @Tom-Elliott Fix pushed.


  • Senior Developer

    @gwhitfield Almost have a fix.



  • Any ideas on what can be done to correct this new wrinkle?



  • @Tom-Elliott - Tried it out this morning and the general settings stay when host screen resolution is updated in group settings. However, something else is now happening, the AD settings for all group members are being wiped out screenshot below):

    Here are Apache error logs:

    Edit: For clarity sake, the AD settings are wiped out only when the host screen resolution settings are updated, not when the general settings are updated.



  • @Tom-Elliott @Wayne-Workman - No way!! That was like watching a sweet give-an-go with a slam dunk finish. SCORE!! Can’t wait to try it out, thanks guys!!!


  • Senior Developer

    I’ve found the issue as described and it is now fixed in the latest.

    @gwhitfield said in some global settings being cleared during group settings update:

    Is this normal or should there ALWAYS be a DB update prompt when executing the install of new svn?

    It’s normal.

    And Tom might be on to something, that’s the command we came up with way back where there was an issue with hosts disappearing…



  • @Tom-Elliott - Since I know zilch about MySQL I can’t talk what-ifs :-) but I take it on faith so I’ll give that a try tomorrow.I’ll send the response as soon as I get a chance to do this step.


  • Senior Developer

    What if you run:

    DELETE FROM hostMAC WHERE hmHostID NOT IN (SELECT hostID FROM hosts)

    You may also need to delete invalid host entries (without a hostname, or now a hostname without a proper MAC address). To do so, run:

    DELETE FROM hosts WHERE hostID NOT IN (SELECT hmHostID FROM hostMAC)



  • @Wayne-Workman One other thought comes to mind. You mentioned possibly something in the DB. I did notice that on a couple recent SVN updates I was not prompted to update/upgrade the DB. Is this normal or should there ALWAYS be a DB update prompt when executing the install of new svn?



  • @Wayne-Workman Wow, that’s very nice of you! I would be happy to let you look but I don’t know that it’s necessary for you to go through all that just yet considering I never really update the screen resolution settings. If you feel that it would be beneficial to YOU then I’m all for it but otherwise it’s not necessary for you to do that. I’ll explain -

    I’m honestly not sure how I even stumbled on this though I WAS trying to figure out how the settings got cleared and I was clicking and checking everything until I found it. Seeing that I usually don’t touch that setting it was probably an accident that it happened at all. Sure, it’s reproduceable but I guess as long as I keep not touching that setting I shouldn’t have any further problems. The odd thing is that it seems to be a “feature” on each system of mine that I’ve checked, 3 or 4 out of 15. I’m going to check the rest, it may be a few days before I know the results.

    Thank you again for your quick responses!!!

    @gwhitfield The output looks good. It was just a shot in the dark. I’m not sure what’s going on with your setup but if this was a bug in fog trunk, we would have many people saying the same thing… we’re not… so this leads me to believe there’s something in your DB that is causing this issue. If you have time, I’d be willing to look around and see if anything stands out via team viewer.

    @gwhitfield Good job at documenting the issue. Can you go to MySQL via CLI on the FOG server and run this select command and give us the results? select * from hosts where hostID=0 \G



  • @Wayne-Workman - Here’s exactly what I’m seeing. It is consistent, happens every time I click screen resolution update when there are existing group settings configured. No errors logged in Apache log.

    @gwhitfield So, that’s one place to get them when the interface fails. You can get logs from Web interface -> FOG Configuration -> Log Viewer -> Apache Error Logs We need the errors (if any) that happen immediately after you try to set settings via a group as you’ve described in your OP.



  • @Wayne-Workman I looked in \var\log\apache2\error.log (I hope that’s the right place?) and see the following:

    I did a couple reboots to try to segregate the logs. Hope I’m getting what you’re asking for, I’m not real linux savvy. I did the last test after the last reboot (about 15:05) and doesn’t appear to have logged any problems.

    I’ve never looked at them so I have to figure that out

    We need the errors, if any.
