    @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

    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!

      mount -a

      I think I’ve messed up the FSTAB:

          @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.
