    @fry_p i think you could just do sudo -c as it will run the commands as if it was run by root interactive, but without going into “interactive” mode of the shell. I’m not 100% sure though.

      Is there a way to embed sudo -iinto the script?

      Maybe just run your script with sudo script.sh??

        @Sebastian-Roth I’m having trouble understanding. Anything I do besides manually putting in sudo -i then running the service restart, I get “permission denied”. Also, the sudo -c throws the same error. This is a tough one. Since I embed my fogadmin account into my script, I’d have to either change that to root credentials or somehow embed both. Right now it is still the MulticastManager doing it.

        Like open source community computing? Why not do it for a good cause?

          @Sebastian-Roth I was overthinking this. I simply added it to the end of my script and set up a cron job as root. For proof of concept, I ran my script as root and it worked!

            Hi, I am getting the same on Debian 8 Git version 7917 FOG Storage Node running inside a Virtual Box on a NAS. Copying the commands listed below as root did not make any difference in my case. Constant 100% processor load.

              @coco65 This is highly dependent upon how you run sudo.

              If you’re running where you first login as a user other than root and they sudo to root, you should run:

              sudo -i <- if you’re logging in to become root.

              To ensure the script being run under sudo get’s root sourcing first run the script as:
              sudo bash -c 'script.sh'

                @Tom-Elliott even if i try to run the script via sudo bash -c ‘script.sh’ high load still remains, that doesn’t fix it. and the problem wasnt there with older trunk versions.

                    @Tom-Elliott what should i do i cannot get away from the cpu burning. Any suggestions?
                    Also i cannot use systemctl like you suggested for 14.04:

                    root@fog-image:/home/fog# systemctl stop FOGMulticastManager
                    systemctl: Befehl nicht gefunden.
                    

                    Ubuntu 14.04 uses Upstart as the init system, the plan to switch to systemd is planned for 14.10+. There are parts of “systemd” that have been used in Ubuntu for a long time, but for most intents and purposes when people say “systemd” they mean systemd-as-init.

                    And it burns for me can someone borrow a fire extinguisher? It’s hot here 🙂

                      @Tom-Elliott - I got tired of sudo so enabled root login. Does sudo -i make any difference then? Tried it.

                        I need solid proof if possible.

                        If you can find a revision where all is working properly and when it stops, I can probably be of more help.

                        Seeing as this seems a sporadic thing and only, to me, seems to appear on Debian based OS’s, I can guess maybe it’s got something to do with the session crontab?

                        Just a guess.

                        I haven’t made a change to the fog services that would cause this to sporadically occur.

                        Normally, when I do see the issue, it’s stuck in a forever loop (the services). This happens when it fails to read data from the database and get’s a 0 data.

                            @Tom-Elliott got it fixed, it’s embarrassing for myself, mysql wasn’t rechable outside 127.0.0.1, some automatic installed security patch (i have this enabled) must caused it (it worked before) i changed the bind in my.cnf away from 127.0.0.1 to 0.0.0.0 you can also use machines current ip address on eth you are using. 0.0.0.0 binds to every network device.

                            No need for any postprocessing script

                            Just an idea, the installer could check the bind address while installing/updating and warn if bind is 127.0.0.1 or localhost.

                            EDIT:

                            Not fully solved my fog master is now burning, maybe 0.0.0.0 is not making it reachable to 127.0.0.1 (localhost)… i get back
                            ok that was not the problem, 0.0.0.0 really binds all access worked via mysql client, so i restarted services on the fog master with the script and it worked, i will try reboots and so on…

                              i did the following and it helped.
                              to installfog.sh at last line i added a call to restart_services.sh
                              additionally i added (as root) to cron (crontab -e) a call to restart_services.sh, use @reboot in front if the crontab line.

                                alt text

                                Now the Multicast Service is burning like hell.
                                After another service restart via script it’s silent again, i will report back tomorrow morning if the hell comes back.

                                      I’ve added some code in hopes to prevent runaway services such as this. With any luck the 100% cpu do to FOG services will be no more.

                                      The Defaults, in case of issues:

                                      FOGImageReplicator = 600 seconds (10 Minutes)
                                      FOGSnapinReplicator = 600 seconds (10 Minutes)
                                      FOGPingHosts = 300 seconds (5 Minutes)
                                      FOGScheduler = 60 seconds (1 Minute)
                                      FOGMulticastManager = 10 seconds
                                      

                                      The writing to log files isn’t as important as the timing. It’s the timing that’s causing the run away CPU cycles as they’re running infinitely. Without a sleep to slow it all down, the services will keep doing work without a break, causing the spikes you’re describing.

                                        Just updated both the fog-server and the fog-node to 7945 on debian 8 both. Nothing has changed I am afraid. The fog server runs fine but the storage node is at a constant 100% processor load. The 4 FOG services (ImageReplicator etc) keep using every processor cycle they can get.

                                          @coco65 Run the script as it was designed earlier.

                                          service FOGMulticastManager stop && sleep 5 && service FOGMulticastManager start
                                          service FOGPingHosts stop && sleep 5 && service FOGPingHosts start
                                          service FOGImageReplicator stop && sleep 5 && service FOGImageReplicator start
                                          service FOGSnapinReplicator stop && sleep 5 && service FOGSnapinReplicator start
                                          service FOGScheduler stop && sleep 5 && service FOGScheduler start
                                          

                                          OR:

                                          systemctl stop FOGMulticastManager && sleep 5 && systemctl start FOGMulticastManager
                                          systemctl stop FOGPingHosts && sleep 5 && systemctl start FOGPingHosts
                                          systemctl stop FOGImageReplicator && sleep 5 && systemctl start FOGImageReplicator
                                          systemctl stop FOGSnapinReplicator && sleep 5 && systemctl start FOGSnapinReplicator
                                          systemctl stop FOGScheduler && sleep 5 && systemctl start FOGScheduler
                                          

                                          This is going to make sure the services have enough time to restart. The Installer appears to not satisfy the “timing” properly.

                                          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.
