    Ok, Reinstall Unbuntu 13.10 and installed Fog v1.1.1 and still hangs at the same place on multicast.

      If you had to “restart” mysql because it “killed mysql” you’ll most likely need to restart the services.

      Here’s the process I imagine:
      [code]sudo service mysql restart &&
      sudo service apache2 restart &&
      sudo service FOGMulticastManager restart &&
      sudo service FOGImageReplicator restart &&
      sudo service FOGScheduler restart[/code]

      The \ just allows you to keep adding to the current command. The && only starts the next command if the previous command completes successfully. If it doesn’t complete successfully it will not run the next, or any other of the commands in sequence. This can help you find out an issue.

        If all restarts and returns properly, you’ll most likely have to restart the clients as the udp-sender commands will start, but there was no communication between the clients and the server before. Just restart the clients and all should start properly.

          No, I started fresh. I wiped and reinstalled Unbuntu 13.10 and then Installed Fog v 1.1.1. Then Uploaded an image. Test pushed the image to a single machine and then tried a Multicast of 2 Machines. It’s still hanging at the “Starting to restore image” part.

                Thanks for your Help Tom. I’m headed home for the weekend. Hopefully we can figure out an answer when I get back to work on Monday.

                Have a Great Weekend.

                  Based on the information, does your network allow UDP traffic to pass?

                    im in the same boat as michael. i reinstalled ubuntu 12.04 lts server. installed fog svn 1820. normal unicast works fine, but the group multicast with more than 1 member doesnt work.
                    here is the multicast.log.udpcast.6 (in this case its a 6) log:

                    Udp-sender 20120424
                    Using mcast address 234.1.1.242
                    UDP sender for (stdin) at 10.1.1.242 on eth0
                    Broadcasting control to 224.0.0.1
                    New connection from 10.103.50.144 (#0) 00000009
                    New connection from 10.103.50.151 (#1) 00000009
                    Starting transfer: 00000009
                    Timeout notAnswered=[0,1] notReady=[0,1] nrAns=0 nrRead=0 nrPart=2 avg=10000
                    Timeout notAnswered=[0,1] notReady=[0,1] nrAns=0 nrRead=0 nrPart=2 avg=10000
                    Timeout notAnswered=[0,1] notReady=[0,1] nrAns=0 nrRead=0 nrPart=2 avg=10000
                    Timeout notAnswered=[0,1] notReady=[0,1] nrAns=0 nrRead=0 nrPart=2 avg=10000

                    it just keeps going.
                    when i multicast to a group with one member, it works. here is the multicast.log.udpcast.8:
                    Udp-sender 20120424
                    Using mcast address 234.1.1.242
                    UDP sender for (stdin) at 10.1.1.242 on eth0

                    Timeout notAnswered=[0] notReady=[0] nrAns=0 nrRead=0 nrPart=1 avg=1155
                    So i notice that for both groups, everthing is the same until Timeout notAnswered=
                    For the group with 1 member, its:
                    Timeout notAnswered=[0] notReady=[0] nrAns=0 nrRead=0 nrPart=1 avg=1220
                    For the group with 2 members, its:
                    Timeout notAnswered=[0,1] notReady=[0,1] nrAns=0 nrRead=0 nrPart=2 avg=10000
                    The group with 2 members, that message keeps on repeating forever, and the client doesnt show any change.
                    The group with 1 member, every so often will update with a:
                    bytes= 29 516 032 re-xmits=0003904 ( 19.2%) slice=0112 - 0
                    If everyone else is getting it to work, then it makes me think the switches on my side are at fault. In which case shame on me for posting this. And shame on my colleagues for messing around with the switches.
                    Please let me know if anyone else is having this issue. I’ll work on my end and post what i found. Im hoping its just a switch where multicast isnt enabled.

                      Hi, I reinstalled fog_1.1.1 and tried again : multicast ok on my virtual network.
                      I will try next week with multicasting 15 real machines on W7

                      Thanks again for your work.

                        I think I know what’s causing the issue with the screen “hanging” at the (-) stuff.

                        Do you have multiple storage nodes?

                        I found an issue presenting exactly as you’re specifying here if you have multiple storage nodes. Chances are, the node it was working off of at the time had less client load and therefore set the “optimalStorageNode” paramenter. This “optimal node” is not a master node so the udp-sender command is not being pushed when the client is requesting it.

                        Hopefully this will help, I’ve told multicast jobs to only set the storage node based on the master node that’s enabled within that storage grouping.

                          As far as multicasting, we’re running 12.04 and 1.1.1. I tried to multicast and received the same Part-clone hang error. Upgrading to r1852 to see if it resolves it.

                              I’m running into the same problem with fog-1.1.1 on RHEL 6.5. I’m pretty much clueless about UDPcast so I’m not sure if the problem is with the network or fog. I can say that everything seems to work with a single machine in the group and fog tells me that it will be using UDPcast for that host.

                              EDIT I should also say that I took a go at running udp-sender and udp-receiver manually (in debug mode on the clients). The results were the same: a single host worked fine, more than one failed, this time with errors like

                              [CODE]
                              Timeout notAnswered=[0] notReady=[0] nrAns=0 nrRead=0 nrPart=1 avg=84698
                              [/CODE]

                                  Sorry, missed your question. No, single node setup, I think my problem is either with udpcast or our network configuration.

                                    For my setup, this looks very similar to [URL=‘http://fogproject.org/forum/threads/multicast-does-not-work-to-multiple-clients-only-to-single-client.863/’]this post[/URL], but their hack with the 239.X.X.X mcast address doesn’t seem to be working for me.

                                      I’m also having this issue, and it is really hard to isolate. In my old setup all sites had their own 0.32 FOG Server using Normal installation, and multicast worked great. The catch with this setup was that the images were “per site” as they each had to point to their respective local FOG servers, and also having one SQL database per site was unmanageable and inefficient.

                                      I’m attempting to downgrade / revert for testing purposes but in my new setup each site has a storage node set to “Master” (because only Master nodes can multicast) AND each site’s storage node is its own storage group. I’m not sure if this is the most efficient setup but I need to be sure which node(s) the machines are pulling their images from (at least for now) and if only Master nodes can send multicast traffic, then it follows that each site needs to have a Master node on its LAN.

                                      I’m in the process of reverting and testing, but where would I find the best multicast debug page?

                                      If there is anything else that I can add, please let me know - I plan on working on this all week…

                                      Ubuntu 14.04 - FOG 1.1.2
                                      Multicast log on main FOG server is empty
                                      Multicast log on storage node does not exist (file not there)
                                      Storage nodes ARE pushing images to clients in unicast mode correctly (tested and verified)

                                      Thanks for any help,
                                      D.L.

                                        To add,
                                        If the storage node is the device actually pushing out the image via multicast, then shouldn’t the logs and UDPcast service and testing be done there? The reason that I’m asking is because the storage node(s) do not seem to have anything related to multi-casting, including the absence of FOGMulticastManager as a service…

                                        I am definitely puzzled,
                                        Thanks for reading,
                                        D.L.

                                          I have a clean install of FOG on Ubuntu 13.10.
                                          I’m having the same issue. Hanging on the Partclone screen.
                                          Unicast is working

                                          Network is very basic.
                                          FOG Server -> unmanaged switch -> PC’s

                                          There is nothing special about the setup.

                                          I start the Multicast and the session seems to end right away. I have rebooted the server and restarted the services indicated earlier in this post.

                                          Here is the dump from my log.
