    @sebastian-roth said in langage de programmation:

    Should be mount /dev/sda1 /ext (space in between!)

    Yes I saw that too.

    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 salut george, oui j’utilise uniquement des ordinateurs linux et je voulais savoir j’utlise le script que tu viens de m’envoyer et comment je pourrais modifier cela à mon besion.

      par exemple je vois partition ntfs cà c’est windows pour linux je remplace avec ext4 ou ext. et le osid 50 mais là je vois osid in 5/6/9 etc.

        @julio I was thinking something like this:

        . /usr/share/fog/lib/funcs.sh
        [[ -z $postdownpath ]] && postdownpath="/images/postdownloadscripts/"

            5|6|7|9)
                clear
                [[ ! -d /ntfs ]] && mkdir -p /ntfs
                getHardDisk

        Understand I did not test this code at all. This code may be more complex than you need if only you set the hostname. The script you have will work if you fix what Sebastian posted about your mount command. I just wanted to show you that you can make the core more responsive if your root partition is not always /dev/sda1. In some cases like UEFI disk format /dev/sda1 is the UEFI boot partition and not the OS root partition. Your code would fail if that was the case. Or if your hard drive is a NVMe type then /dev/sda (points to sata) would be wrong and the script would fail because nvme disk have a different partition structure.

        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 works the same. I was just warning if you use real hardware that it could change the way your script runs because hardware changes.

                    @julio I will give you a hint to maybe help you with your scripting.

                    FOG has a special mode you can use to debug your programs right on the target computer. So do the following.

                    1. Register your VM with fog (if you have not done so already)
                    2. Schedule a new deployment task, but before you press the Schedule Task button, enable the Debug checkbox, then schedule the task.
                    3. PXE boot the target computer.
                    4. After several screens of text, you can clear by pressing the ENTER key. You will land on the FOS LINUX command prompt.

                    Now run lsblk to find your hard drive. See if you can find from lsblk your root partition.

                    Now manually run

                    mkdir -p /ntfs
                    mount /dev/sdaX /ntfs
                    

                    Just as a test run the echo command the variable ${hostname} will not be set yet so you can’t use it here. But you can find out the right location and partition to use. You will not see all of the loop devices that ubuntu creates so it will be clear what partitions you want.

                    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!

                      This is why I suggested to test your program using FOS Linux in debug mode. No chance to break your FOG server.

                          @julio When you added the echo "OK, osid is 50/Linux" into your script, did you see that message on the console??

                          You might want to add the mentioned read command as well so it waits for your input…

                          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)

                          Please support FOG if you like it: https://wiki.fogproject.org/wiki/index.php/Support_FOG

                            comment verifier que le script est bien fonctionnel???
                            j’ai bien donner les droits d’execution à savoir chmod +x renamehost.sh

                                  @julio To get into debug mode on the pxe booting computer make sure you enabled debug mode.

                                  Screenshot from 2021-02-02 17-42-30.png

                                  See the Schedule as debug task option? When you do this and pxe boot the target computer you will end at the FOS Linux command prompt.

                                  In your script for debugging purposes you should add

                                  echo "Some step in the script"
                                  debugPause;
                                  

                                  This way you will know when and where your script is in the program. I add these quite often at specific points in my scripts.

                                  Also make sure you add your script like fog.custominstall or renamehost.sh to the master script of fog.postdownload or your script will not be called by fog.

                                  IF you are ready to debug your script AND you are at the FOS Linux command prompt key in fog to start the deployment. The FOG deployment will stop at all of the debugPause commands during deployment. Press enter to go to the next step. When / IF you get to see OK, osid is 50/Linux on the screen and you see a bug you can press CTRL-C to exit the script. The FOG Postinstall scripts are run right after the last partclone copy screen. You can fix what you need then restart the deployment process again by typing fog in again. You can do this testing as many times as you want without needing to reboot the pxe target computer.

                                  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!

                                          @julio said in langage de programmation:

                                          ’ai reussi à entrer dans la partition de debogage. j’ai executer la commande lsblk. voici ce que j’obtient

                                          Ok I see only one partition then /dev/sda1. Now you know what your target partition is.

                                          donc le script essaye de s’executer mais petite erreur.

                                          Here is an example of my if/then

                                                  if [[ -z $hd ]]; then
                                                      handleError "Could not find hdd to use"
                                                  fi
                                          

                                          When you look at your if / then statement do you see any differences? How about spacing?
