      This problem is exactly like - https://forums.fogproject.org/topic/4979/problem-mounted-file-system-permission-denied-solved

      I have followed advise from wiki as well and other posts.

      Running Ubuntu Server LTS 16.4.3 with install of PHP7 as per wiki advice for that OS.
      There was no /home/fog/images and images/dev with requisite files so created that. Strangely, images folder is sitting in root directory rather than /home/fog.

      How do I resolve this please? What log file can I attach?

        Will you please post a clear screen shot of the error taken with a mobile phone. The context of the error is almost as important as the error line itself.

        Is this a new install of FOG, or was it running for a while then magically stopped?

        The images folder should be in /images that is the default location. If you moved it someplace else during install then we need to address that.

        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!

          I kind of doubt that yours is exactly like that. The post is two and a half years old and FOG 1.2.0 was the official release back then. I hope you don’t still use version 1.2.0 as we don’t support that anymore. Current stable version is 1.4.4 as of today. Please let us know which version you run.

          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)

            rebooted my server this morning and came up with an nfs-mount error. Need to sort this out first to get back up and running.

            To answer above as best I can in the meantime:
            The screenshot in the picture showing the line “permission denied” is exactly what I am getting except for my IP. Maybe related to NFS issue above?
            Loaded latest version 1.4.4.

            Once I have NFS sorted will post again with results.

              @majikins on the fog server, lets run showmount -e 127.0.0.1 that should show you what nfs shares are exported on your FOG server.

              Also for clarity, you are exporting space on your fog server to storage media (hard drive) that is directly attached to the fog server and not cross mounted to some external nas device, right?

              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!

                showmount -e 127.0.0.1

                I think I know just enough to cause problems. Syntax on my /etc/fstab mount for an lvm volume was wrong and my box freaked on restart.
                On diagnosing, I think I may have an inkling. I mounted an lvm volume for images and made this a default storage container on the web interface. I’m assuming that write rights need to be given to fog user for this to work? Is the /images/dev and /images being mapped to my mount as storage? to answer question above:

                Export list for 127.0.0.1:
                /images/dev *
                /images *

                The computer I was imaging is otherwise engage and will only be able to test this evening again.
                Thank you for all the responses!

                  @majikins Please run the following commands and post pictures or listings here: mount and ls -al /images /images/dev and cat /etc/fstab (note the spaces in the commands!)

                      That LVM is mounted to /mnt/share which probably FOG is not aware of. Take a look at the storage node configuration in the web UI. I recommend to stick to the default path /images. It’s easier to move things around and leave the FOG default path for it as is.

                      So depending on what you have in /mnt/share already (see with ls -al /mnt/share) - assuming it is mostly empty - I’d go like this:

                      sudo -i
mv /images/* /mnt/share
mv /images/.mntcheck /mnt/share
umount /mnt/share

                      Now edit /etc/fstab and change /mnt/share to simply /images. Then remount that mount /images and you should be all setup.

                        @sebastian-roth Thanks - couldn’t wait for computer so created a Virtualbox session and got the same error after following your instructions. Please see screenshot0_1513795544248_fog error.PNG

                          @majikins See in that picture it says storage=x.x.x.x:/media/dev which is different to the other information we have. Seems like someone has messed with that setup a fair bit. Not sure what advice I should give. Maybe a clean reinstall would be best, not sure.

                            @sebastian-roth Thank you and everyone replied for help and patience. That someone who messed up is me 🙂 This is a test server so going to be far more efficient to reload.

                            Thanks again everyone.
