      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

        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:

          root@PDC-FOG:/# mount -a
mount: special device /sdb1 does not exist

          Did I do something wrong?

              @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)

                              Will I need to recapture my image now?

                                @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.

                                  Seems to be replicating now! Thanks!
