      @Technolust said in New Fog Server - /images location:

      however, when there is an upgrade will the upgrade know the location?

      Yes your answers to the questions are stored in a hidden file in /opt/fog/.fogsettings That file is referenced each time the installer is run, even between version upgrades.

      Also what is the difference in the installer between Normal/Storage?

      A “Normal” install is a traditional FOG server with webui. A Storage [node] is a deploy only server that has no web gui, a storage node must connect to a Normal mode FOG server to be functional. You would use storage nodes, maybe at remote locations so you can deploy images locally to target computers at the same site as the storage node.

      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!

        Awesome, Thanks George. Running through the installer now and just saw the installer explain the difference… Haha, Reading is fundamental…

          Hey George,

          The installer doesn’t ask you for a location it automatically chooses the install location.

          What version of Linux would you like to run the installation for?

                1) Redhat Based Linux (Redhat, CentOS, Mageia)
                2) Debian Based Linux (Debian, Ubuntu, Kubuntu, Edubuntu)
                3) Arch Linux
          

          Choice: [1]

          Starting Redhat based Installation

          FOG Server installation modes:
          * Normal Server: (Choice N)
          This is the typical installation type and
          will install all FOG components for you on this
          machine. Pick this option if you are unsure what to pick.

            * Storage Node: (Choice S)
                This install mode will only install the software required
                to make this server act as a node in a storage group
          

          More information:
          http://www.fogproject.org/wiki/index.php?title=InstallationModes

          What type of installation would you like to do? [N/s (Normal/Storage)] Normal

          What is the IP address to be used by this FOG Server? [10.141.0.20]

          Would you like to change the default network interface from ens160?
          If you are not sure, select No. [y/N] n

          Would you like to setup a router address for the DHCP server? [Y/n] y
          What is the IP address to be used for the router on
          the DHCP server? [10.141.0.1]10.141.0.27

          Would you like DHCP to handle DNS? [Y/n] n

          Would you like to use the FOG server for DHCP service? [y/N] n

          This version of FOG has internationalization support, would
          you like to install the additional language packs? [y/N] n

          FOG now has everything it needs for this setup, but please

          understand that this script will overwrite any setting you may

          ######################################################################

          It is not recommended that you install this on a production system

          ** Notice ** FOG is difficult to setup securely

          SELinux and IPTables are usually asked to be disabled

          There have been strides in adding capabilities

          The recommendations would now be more appropriate

          to set SELinux to permissive and to disable firewall for now.

            @Technolust Well color me wrong. I’m pretty sure it use to…

            If you look in the /opt/fog/.fogsettings file does it contain a field for /images?

            We can manually fix it, but it would be swell if it retained the settings for the next install.

            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!

              @george1421 No worries man, should I just go ahead and go through with the install afterwords and see if we can change it? I will take an image of the server and revert back to it if I need revert back. I’m asking because I don’t have the /opt/fog directory configure yet because I canceled the install.

              Thoughts?

                @Technolust Well confirm that the… let me remote into my office and see if the field is there. Lets not do a bunch until we know. We can make it work like you need it. Give me a few minutes to double check things.

                  @Technolust OK I just looked and there IS the field in question. Its called storagelocation. Go ahead and do a normal install, let it default to /images

                    @george1421 Just open thoughts on changing storage location.

                    1. Update .fogsettings storagelocation field.
                    2. Update /etc/exports to from /images and /images/dev to new locations /fogserver/images and /fogserver/images/dev
                    3. Copy everything from /images to /fogserver/images
                      cp -r -f /images/* /fogserver/images
                    4. Make sure directory permissions match between /images and /fogserver/images
                    5. In the web ui update Fog Settings->Fog Configuration Expand all settings and then search for /images and replace with proper path
                    6. Go to default storage node settings and update /images to /fogserver/images
                    7. Then back to the linux command prompt and rerun the fog installer script.
                    8. Double check /etc/exports to ensure that /fogserver/images is still shared.
                    9. Reboot the fog server
                    10. At the linux command prompt key in showmount -e 127.0.0.1. It should show /fogserver/images being exported after a reboot.

                    That should do it.

                    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!

                          No you better set a proper mysql root password before installing FOG. We are working on the installer to pilot people to set passwords.

                          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)

                              @george1421 Hey George, in step 5, the Web GUI -> Fog Configuration -> Fog Settings -> Expand all -> there is no /images location. Should there be any specific settings? In step 6 do I also change the FTP path to /fogserver/images from /images? If so I did that as well. Finally step 10 - Looks good.
                              Export list for 127.0.0.1:
                              /fogserver/images/dev *
                              /fogserver/images *

                              Can you tell me if this will need to be performed for every update or will fog server updates keep these settings?

                                fog.PNG Should the Storage Node show online?

                                When I go to storage nodes it is up and running.

                                  Sorry I wrote that post from memory since I didn’t have immediate access to a fog console to verify.

                                  also change the FTP path to /fogserver/images from /images?

                                  Right you need to change everywhere you would see /images to the new images path.

                                  It looks good for the export list.

                                  If you updated the .fogsettings file in step 1 then no, it should be automatic moving forward.

                                    @Technolust What does the content of the default storage node look like?

                                    Also did you reboot the fog server after you made all of those changes? Some values are only loaded at boot time.

                                      @george1421 Thanks, I did make the change for the ftp path and I did update the .fogsettings in step 1 as well as rebooted the server. Only thing now is the Storage Node not coming online.

                                      /fogserver/images/

                                        @Technolust I don’t have a clue about the storage node on the home screen. But from your ls command you are missing 2 check files. If you run ls -la on the old /images directory you will see a file called .mntcheck and the second one of the same name needs to be in /images/dev. Those will need to be recreated in your new location paths. You can simply do:
                                        touch /fogserver/images/.mntcheck
                                        and
                                        touch /fogserver/dev/images/.mntcheck

                                        its ok if they are already there, that touch command will just update the last time the file was access, or create it if it wasn’t there.

                                          touch /fogserver/dev/images/.mntcheck

                                          Ok looks like /fogserver/dev/images doesn’t exist. Is this supposed to be /fogserver/images/dev?
                                          If so I ran touch touch /

                                          [root@fogserver images]# ls -la /fogserver/images/

                                            @Technolust said in New Fog Server - /images location:

                                            touch /fogserver/dev/images/.mntcheck

                                            Ok looks like /fogserver/dev/images doesn’t exist. Is this supposed to be /fogserver/images/dev?

                                            OK its time for either another cup of coffee or for me to just go back to bed. The path /fogserver/dev/images is of course wrong. I should have typed /fogserver/images/dev

                                            It looks like you have the check file in the proper paths from your ls command. But after a reboot your storage node is still showing off-line?

                                            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!
