FOG Multicast Problems / Partclone fails to finish



  • I have FOG server 1.2.0 currently installed on an Ubuntu 14.04 Linux desktop Virtual Machine and a FOG Storage Node installed on a another Ubuntu 14.04 Linux desktop also a Virtual Machine. We have a Windows Domain Controller and a Windows DNS server one running Windows Server 2008 and the other Windows Server 2012. We are a school and all of our clients are either Windows 10, Windows 7 (mostly) and some Windows XP.

    I have had many hurdles in installing and running FOG. Currently, I have finally gotten Unicast figured out and running. However, I cannot get multicast to run. Partclone gets to the start screen and then will not finish.

    I have gone through this wiki:
    https://wiki.fogproject.org/wiki/index.php?title=Troubleshooting_a_multicast

    But cannot figure out how to:
    “Now boot up 1 client go to your FOG Menu and select debug mode.”

    The server starts udp-sender just fine with no errors. I can also log in and move my files around in FTP on all of my storage nodes. My FOG Storage is the default storage node.

    My FOG Multicast Settings are:

    FOG_UDPCAST_INTERFACE = eth0 (which is correct)
    FOG_UDPCAST_STARTINGPORT = 58166
    FOG_MULTICAST_MAX_SESSIONS = 64

    It sounds like some of these problems have been resolved in TRUNK but I cannot figure out for the life of me how to install the TRUNK version in UBUNTU 14.04.

    I know my network settings are correct because I can use Clonezilla multicast just fine.

    Any help is greatly appreciated.

    I’m a longtime linux/unix user but it’s been a while, so please dumb down the replys a bit. Thanks!!

    Cheers,

    Joe Gill



  • @Tom-Elliott

    The group settings change in the update fixed the problem!

    Thanks!


  • Senior Developer

    Group, and all the other originally broken (but kind of unkown to most) are now fixed.

    Please verify for sure, though I have tested just to be somewhat safer.

    the multicast session I had problems with… Just took off!

    That’s what we call the multicast wait time. The default is 10 minutes, which I think is a bit much in most cases. At work, mine is set at 2 minutes.
    Web GUI -> FOG Configuration -> FOG Settings -> Multicast Settings -> FOG_UDPCAST_MAXWAIT



  • @Tom-Elliott

    Awesome! Tom on that note, the multicast session I had problems with… Just took off! So… I jumped the gun! I apologize! Thanks!!



  • @Wayne-Workman

    Ok this is bizarre! I restarted the servers, cleared the DB of non-essentials, stopped and restarted services. Everything appeared to be going well, until it got past the first two partitions. Than the session locked up at the last partition…

    I tailed the log file and it showed this…

    Any ideas?? I’ll be around until 5:30 PM MST this evening… Thanks!


  • Senior Developer

    @Joe-Gill I know what’s wrong with the groups, and all other similar type things but I need to drop my truck off at the shop. All will be fixed in a couple of hours ok?



  • @Wayne-Workman

    No problem.

    I will create a new post for the group problems.

    As for the multicast issue, I have followed the Wiki on clearing the DB. That went smooth. I’ll retry this issue now. Thanks!

    @Joe-Gill That would be another seperate problem in the current fog trunk that probably doesn’t directly impact the multicast process I’m trying to help you with. Please create a bug report about adding hosts to groups, provide your version and the exact click-for-click steps you’re doing - also include apache error logs from Web Interface -> FOG Config -> Log Viewer -> Apache error logs.



  • How about adding members to a group? I can’t add any members to new or existing groups.

    I’m also experiencing an issue reading the Dashboard disk usage. I can send you a screenshot of that if you’d like.

    Post that to this thread:
    https://forums.fogproject.org/topic/7875/storage-group-activity-inconsistencies

    Also, try to clear out multicast stuff in your DB with commands found in here:

  • @Tom-Elliott @Wayne-Workman

    Well I updated via SVN. Still have the issue. I’m also experiencing an issue reading the Dashboard disk usage. I can send you a screenshot of that if you’d like.

    You cannot delete members of existing groups…

    Also cannot add members to new groups…

    Any help is greatly appreciated.

    Thanks!

  • @Tom-Elliott

    So what’s the easiest method to update FOG?


  • Senior Developer

    @Joe-Gill not even close. We’re not trying to update kernels. You need to update FOG as a whole.



  • @Tom-Elliott

    Wed Jun 29, 2016 12:17 pm
    Running Version: 8140
    SVN Revision: 5698

    Is that current? I don’t see any options under …

    Fog Configuration > Kernel Update >> Published Kernel




  • Senior Developer

    Re-update and see if it is working?



  • @Developers
    .
    Any thoughts here?



  • @Tom-Elliott

    My problem is back again. I tried shutting down and re-starting service but I’m hanging up again at the Particlone screen.

    Ran this on both Storage Node and Server…

    root@Fog:/# ps ax | grep udp
    12432 pts/1    S+     0:00 grep --color=auto udp
    root@Fog:/# service FOGMulticastManager stop; sleep 5; service FOGMulticastManager start
     * Stopping FOG Computer Imaging Solution: FOGMulticastManager           [ OK ]
     * Starting FOG Computer Imaging Solution: FOGMulticastManager           [ OK ]
    

    Also…

    Tailed the Multicast Log File on Storage Node below…

    I’ll be here all day. I’m working on imaging a lab. Thanks!!
