    Ubuntu 14.04, FOG r6263 upgraded from 0.32.

    Starting a deploy (unicast) with 6 clients.

    I am having one storage group with two nodes where each of them has the limit of 3 clients.
    So each node should take care of 3 clients. When all clients show the partclone screen the speed differed and i checked connections on the nodes.
    Node 1 had 4 open nfs connections and the node 2 had 2 open nfs connections. Seems there is somthing wrong in the allocation of the clients?

      What? I’m lost, what is wrong?

      It get’s optimal node based on load, but there is no requirement for it to just split evenly.

      Please help us build the FOG community with everyone involved.

        Doesn’t FOG split the clients correctly to fulfill the max client option?

        A deploy with 6 clients is split into:

        • First node serves 4 clients.
        • Secound node serves 2 clients.

        Shouldn’t each node serve 3 clients when the option max clients is set to 3?

          @mp12 I still don’t understand.

          Both nodes only have a max of three clients?

            Yes both nodes have a max of three clients!

            Deploy of six clients is split into four and two on the nodes.

                  Am I missunderstanding the storage managment?

                  From FOG Wiki:
                  Each storage node has a setting Max Clients making this the maximum number of hosts that this node can image to
                  

                  In my config each node should image to thrree clients.

                      @mp12 Can you set one node to zero and the other to 1 and see what happens when you deploy two? Then swap the 1 for 0, and then one that was previously set to 0, set that to 1. Then try again with two host imaging tasks and see what happens?

                      Right now - it’s clear there is some sort of issue, but knowing how it behaves in various conditions will help us locate exactly where the issue is.

                        DOes it actually image 4 clients on the system or is one of the clients waiting for a slot to free up?

                            @Wayne-Workman I tried some scenarios (lots). With different number of max clients and different number of clients which get a deploy. See spreadsheet for details.

                              @mp12 Is this still a problem?

                              I updated the code base for the getUsed/getQueued hosts. I’m not sure it will do anything, but status update would still be nice if at all possible.

                                @Tom-Elliott upgraded to r6285.

                                No effect here. Started task with four clients.
                                Max client on both nodes is set to two.

                                Only node1 processes the four image tasks.

                                  @mp12 This seems, to me, to be a timing issue. What happens if you slowly let the clients check in rather than all try to beat the clock?

                                    @Tom-Elliott thanks for the tip.

                                    Same setup as before.

                                    node1 max client 2
                                    node2 max client 2
                                    number of deployed clients 4

                                    Started the deploys with a delay of 10 sec. between each client.
                                    I tested it via basic tasks/deploy and with the clients boot menu/quick image.

                                    The clients got split correctly. This seems to fix the problem?!

                                    Tested a delay of 7 sec. and the split got messed up.

                                      @mp12 this gives me a starting point on what I can do to try to fix the problem you’re seeing. I don’t know why time matters but apparently it does.

                                      I’ll see if I can make things work properly but trying to race between quite literally seconds is not a simple feat.
