      @weidongyan As mentioned there are different ways of doing this. I myself would tend to use a proper hardware RAID controller or use LVM. The later one doesn’t cost any money, is pretty flexible and easier to use than software RAID (a.k.a. mdadm in Linux) from my point of view. But that’s just what I am used to.

      I just want to emphasize what George already mentioned. Make sure you simply mount the storage you create from those disks in path /images in your FOG server and life will be pretty easy from the FOG side.

      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)

        @Sebastian-Roth Hi, Sebastian, I just created one storage pool and it is mounted in the path of /storage-pool. So right now I need to install fog server and move the storage pool to /images. Is that right? How could I move the storage? I am new about this.

          @weidongyan What does your /etc/fstab look like? (post it here).

          Really before you install fog you want to mount your storage pool over the /images directory so your storage pool will look transparent to FOG. The FOG installer script does a lot of things to make sure your FOG image repository is setup correctly, that is why its important to have the /images directory created and then your storage pool mounted to /images.

          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 when I created the storage pool, it automatically created at the path of /storage-pool/, how could I change the path of it to the /images? just copy the fold to /images?

                You can see that in the root there is a fold called storage-pool

                  @weidongyan Well from the fstab you posted it doesn’t look like your storage pool is going to be mounted at all. Run the following two commands and post the output you get here:

                  lsblk
mount
df -h

                  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)

                      @weidongyan Ok, I see, you decided to use ZFS. You should be able to adjust the mount point of that ZFS storage pool following the instructions here: https://docs.oracle.com/cd/E19253-01/819-5461/gaztn/index.html

                      As well please run zpool status and post output here.

                      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 Hi, George. Right now I found that the directory /images has been created and fog server has been installed. Is there any way to fix this to use the storage pool that I created? I did not mount the volume before the installation of fog server.

                                @george1421 I realized that I mounted the storage-pool after the installation of fog server and the /images has some folders there before I mounted. Should I uninstall fog server to start again?

                                  @weidongyan Well I don’t see your storage pool mounted anywhere.

                                  What does lsblk show?

                                  Wait you change the post I see the /images mounted now. Rerun the fog installer with the /images mounted now. That should fix the /images directory.

                                  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!

                                    After the fog installer is complete run this command ls -la /images and post the results here.

                                        @weidongyan ok that’s good. The FOG images directory is setup correctly. Now as long as after a reboot the /images directory is mounted then you should be good to go.
