      I keep getting this on /opt/fog/log/multicast.log

      StorageNode Not found on this system.
      StorageNode Not found on this system.
      StorageNode Not found on this system.
      StorageNode Not found on this system.
      StorageNode Not found on this system.
      StorageNode Not found on this system.

      No multicast for me…

      I followed the Troubleshooting steps for Multicast and booted clients on debug mode and that all works great…

      I already checked permissions on /images to be 777
      fog is the owner of images chown -R /images
      .mntcheck files exist in /images and in /images/dev
      NIC is set to ens32 instead of eth0
      /etc/exports are correct
      firewall disabled by systemctl disable firewalld
      selinux disabled:
      [INDENT=1][FONT=monospace][COLOR=#000000]sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/’ /etc/sysconfig/selinux[/COLOR][/FONT]
      [FONT=monospace][COLOR=#000000]sed -i ‘s/SELINUX=enforcing/SELINUX=disabled/’ /etc/selinux/config[/COLOR][/FONT][/INDENT]
      already restarted the nfs-server and all fog services FOGMulticastManager, FOGImageReplicator, FOGScheduler…
      I can upload images
      I can unicast to clients
      re-ran the install script
      still:

      StorageNode Not found on this system.

      I did notice that the time on the multicast.log does not match the time on the system… would that affect anything???

      running the “date” command returns the correct time, but multicast.log has time offset of

      Right now its 11:38AM, but the log indicates:

      [08-21-14 6:38:24pm] | StorageNode Not found on this system.

      Any ideas???

          Here’s the code to fix the installer for MySQL in all redhat based distros. I tested it on my own system and it should work.
          Still stuck on getting multicast working.
          [CODE]ConfigureMySql()
          {
          echo -n " * Setting up and starting MySQL…";
          RHVER=rpm -qa|grep release|xargs rpm -q --queryformat '%{VERSION}'|cut -c -1;
          if [ “$RHVER” == “7” ];
          then
          systemctl enable mariadb.service >/dev/null 2>&1;
          systemctl restart mariadb.service >/dev/null 2>&1;
          else
          chkconfig mysqld on;
          service mysqld restart >/dev/null 2>&1;
          service mysqld status >/dev/null 2>&1;
          fi
          if [ “$?” != “0” ];
          then
          echo “Failed!”;
          exit 1;
          else
          echo “OK”;
          fi
          }[/CODE]

            Here are the lines neccesarry to make NFS work in the install script. Could use the same selector template for rhel 7 versions as the code above in NFS, but it might be better to generalize something.
            [CODE] systemctl restart nfs-server.service >/dev/null 2>&1;
            systemctl restart rpcbind >/dev/null 2>&1;
            systemctl enable rpcbind >/dev/null 2>&1;
            systemctl enable nfs-server.service 2>&1;[/CODE]

              So I no longer think Multicast not working on CentOS 7 is related to a database issue. Tested by importing a functional Centos 6.5 Fog 1.2 database to the CentOS 7 install of fog and updating the users privileges. Anybody got any ideas?

                Any update with CentOS 7 and Multicast issue? I managed to have a functional fog server (as far as tested) except Multicasting (“StorageNode Not found on this system”).

                  To get multicast working on CentOS7 you’ll need to modify the following line in function getIPAddress in /var/www/html/fog/lib/fog/FOGCore.class.php

                  from:
                  [CODE]exec(“/sbin/ifconfig | grep ‘[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}’| cut -d’:’ -f 2 | cut -d’ ’ -f1”, $arR, $retVal);[/CODE]

                  to:
                  [CODE]exec(“/sbin/ip addr | grep -o ‘[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}.[0-9]{1,3}/[0-9]{1,2}’ | cut -d/ -f1”, $arR, $retVal);[/CODE]

                  If you have multiple interfaces with IP addresses you might need to use the following in the first portion of that line

                  [CODE]/sbin/ip addr list eth0[/CODE]

                  Replace eth0 with the interface you use for fog.

                  I haven’t tested this with Ubuntu but if the system has iproute2 package installed it should work.

                        Hey all,

                        Just wanted to let you know I’ve “baked” some of the found items in here into the installer and system. FOGCore will check ip’s from ifconfig, if nothing is found will attempt with ip addr. The installer should take into account the systemd inclusion on CentOS/Redhat 7 now as well.

                        Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG! Get in contact with me (chat bubble in the top right corner) if you want to join in.

                        Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

                          On this subject, I’ve successfully installed FOG on a vm(CentOS 7) and have had some trouble throughout. I used MariaDB for the database and was able to get a registration menu. However, when I go to upload my first image, I get this error:

                          *Mounting File System…mount: mounting <ip address>/images/dev on /images failed: Operation not supported

                          I do have .mntcheck files in each the /images and /images/dev dirs and am trying to use the FOG server as the storage server as well. Any ideas on what to check? I’ve googled and gone through forums but any direction will help greatly!

                            Did you check the right of each folder ?

                                Thanks for checking in, Tom and ch3i.

                                I am using iptables and selinux because we must with our environment.

                                FOG Version: 1.2.0
                                OS version CentOS 7

                                There are no log messages in the apache error log around the time I try to upload the images from the client machine. I am going through the wiki now but I think it’s an issue with FOG trying to mount /images and /images/dev. I’m new to FOG so please be gentle. Oh, here are the perms/ownership on /images and /images/dev:

                                stat /images
                                File: ‘/images’

                                I did have to run #restorecon -Rv /tftpboot to get a Fog menu. Before that, it was permission denied due to the attribute settings on tftpboot. Now the process halts as described in the previous post.

                                  First make sure nfs is actually running with [code]service rpcbind restart; service nfs restart[/code]

                                  If iptables is blocking the ports nfs uses you may have to figure out which are in use and unblock them from iptables.

                                    Is the nfs-server running? What is the output of the following?

                                    [CODE]systemctl status nfs-server[/CODE]

                                    If it is not running, run the following:
                                    [CODE]systemctl enable nfs-server
                                    systemctl start nfs-server[/CODE]

                                    You should test this with iptables and selinux disabled first to make sure everything works as expected.

                                      systemctl enable nfs-server
