    @msnyder Just for clarity you can’t login into the webgui or the linux console.

    What user are you trying to login as?

    If you can access the FOG server linux console, can you tail the apache error log to see if its throwing an error?

    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!

      Turns out I’m out of space…

      I’m able to log into Bash, but can’t find the image to delete it…

      /images/dev/???

        @msnyder ok out of space is an issue for linux. Typically it will crash the OS, so if its still running you are lucky.

        There shouldn’t be any images in /images/dev/<mac_address> If they are there then your captures have failed. You can delete the directories in /images/dev that are mac addresses only. There are other files in there that FOG needs to run.

        You may have to purge an image directory out of /images/<image_name> to get enough free space for the OS to run. Once that is done then you have a few options. Remember that your images AND snapins are by default stored on the root partition. This is not something I like to do in a production environment, but that is the default for many linux distros.

        1. In crease the size of the hard drive fog is installed on
        2. Add a new hard drive (vmdk, vhd) to the FOG server and map that new disk over the /images directory after you copy the contents out.

          Interesting that a 9GB install turned into a 95GB image before it crashed…

          How would one map /images to a newly added drive?

            @msnyder You can start with this process: https://forums.fogproject.org/topic/6642/moving-fog-s-images-files-off-the-root-partition

            Or the simpler way (if your fog server is on a virtual host server) is to just add a new disk to the virtual client.

            Identify the new disk with lsblk
            create a partition on the disk with fdisk /dev/sdX
            Format the partition with mkfs.ext4 /dev/sdX1
            mount the partition to a tmp directory like /mnt mount -t ext4 /dev/sdX1 /mnt
            Move all of the files from /images to /mnt (that the new disk is mounted over) mv /images/* /mnt and mv /images/.* /mnt
            Unmount the new disk umount /mnt
            Update the fstab to mount /dev/sdX1 to /images.
            Run the mount command to remount all of the partitions mount -a
            Confirm it has been mounted df -h
            Double check to make sure the directory permissions are still accurate

                  @msnyder Glad you have it worked out.

                  just confirm now in /images and /images/dev that you have the hidden file .mntcheck with ls -la /images and ls -la /images/dev and you should be all set.

                  I would also reboot the FOG server to make sure everything survives a reboot. That way 6 months from now you don’t wonder what happened to all of our images. 😉

                      I’ve captured my first image and it doesn’t seem to be replicating to my storage nodes… Could this be becasue I moved the /images to a new drive?

                        @msnyder no if the /images reconnected to /dev/sdb1 then the mount is good. Do the replicator logs in /opt/fog/log give you any idea?

                          It appears that even though the capture completed on the machine, the image is staying in /images/dev/<macaddress>…

                            @msnyder Make sure your permissions are set correctly for /images

                            They should be owned by user fog:root right or wrong the file permissions are 777

                                @msnyder This should do the trick: chmod 777 /images

                                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

                                    @msnyder You will need to capture the images again (or be sneeky and move the /images/dev/<mac_name> to /images/<image_name> as the <image_name> is exactly defined in the image configuration. mv /images/dev/<mac_name> /images/<image_name> The capture is complete it just needs to be parked in the right location.
