Multicast ended good. Next multicast session problems



  • Hello,

    First of all, FOG is very nice tool and i already have more then 1500 hosts in the listing.

    But now I have a problem with the multicast session after i updated FOG to 1.5.8
    The problem is when a multicast session is ended the udp-sender still exsist and there is still a record in the database from this session.
    When i start next time a multicast session with other clients the session won’t start at all. I need to clear the database, kill the upd sender and need to restart the FOGMulticastManager and then i need to restart the multicast session and all clients in the group should be restarted.

    mysql -u root <-p password> fog
    truncate table multicastSessions;
    truncate table multicastSessionsAssoc;
    exit;
    
    sudo service FOGMulticastManager stop
    sudo killall udp-sender
    sudo killall udp-sender
    sudo killall udp-sender
    sudo service FOGMulticastManager start
    

    I’m out of any suggestions to try. Is there anything that i can try?

    Thanks in advance!

    @Eazis Sounds good, thanks for the feedback!



  • @Sebastian-Roth we have just tried some multicast sessions and it looks like that everything is working well now.



  • @Sebastian-Roth i will try this and i come back if this fix the solution. It could take some days.

    @Eazis I suppose you are still using FOG 1.5.8!? I just remembered that we did fix some things related to stuck multicast tasks since 1.5.8 was released and you might want to upgrade to the latest dev-branch to see if this fixes your issue.



  • @Sebastian-Roth

    I’m starting the multicast session in this way:

    • Create a group or use an exsisting group
    • Add the members to the group (most of the time 10 members are in this group)
    • Add a group image to this group
    • Add snapins to this group
    • Basic tasks -> Multicast

    @Eazis There are different ways of starting multicast Sessions. Please tell us exactly which one you are using.
