      Okay, removed the offending one using rm -rf /images/dev/c8d9d2d4c8ac df -h shows:

      It’s a 500gb VHDX though, surely this shouldnt be full?

        @RogerBrownTDL On the long run you need to look into purging some of the images and/or extending the disk space.

        The other outputs you posted show that the root partition (LVM) really is only 100 GB in size while the whole VMDK container is 500 GB.

        Extending the space is a bit more advanced but should be possible for you to achieve as well because things seem to be prepared already. After the reboot of the VM run the following commands and post output here:

        pvs
        vgs
        lvs
        

        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)

            lvextend -L +398g ubuntu-lv --resizefs
            

            You may need to reboot for it to take effect. This will use all the remaining LVM volume space for your logical volume. You can’t go smaller after the fact, so be sure you want to use it all first.

              to confirm, this will mean I can actually use the box to it’s full 500gb drive allocation?

                @RogerBrownTDL Yes.

                lvextend - Increase the volume size
                -L - Specify the size to increase it by
                ubuntu-lv - The name of your logical volume (as reported)
                --resizefs - Resize the EXT{2|3|4} file system

                  In which case based on the output here:

                  Please specify a logical volume path.
                  Run `lvextend --help’ for more information.
                  root@tie-fogdeploy-01:~#

                  Would it be lvextend -L +398g ubuntu-vg --resizefs ?

                    @RogerBrownTDL Try this instead:

                    lvextend -L +398g ubuntu-vg/ubuntu-lv --resizefs

                          @lukebarone I am wondering if it’s wise to create another volume instead of extending the existing one. This way the images could be put on the separate volume/partition and would not be able to fill the root partition. But that’s just me trying to prevent this from happening again.

                          The downside of my proposal is that the existing 100 GB root partition can’t be used by images and therefore are kind of wasted because the FOG server itself will never use 100 GB disk space with the images on a separate partition.

                          So maybe it’s actually wise to just extend as proposed and @RogerBrownTDL needs to keep an eye on the disk space from now on.

                          So if you wanna go this path, do:

                          lvextend --extents +100%FREE ubuntu-vg/ubuntu-lv --resizefs
                          

                          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 So obviously as a Linux noob, I know very little… I’m purely (I know, insert puke emoji here) a Windows Sysadmin. If I understand it correctly the way i’ve got it setup is like having a single big C:\ and all i’m wanting to do is get the entire fog server to see it all rather than just a partition of it… If I follow that command
                            “lvextend --extents +100%FREE ubuntu-vg/ubuntu-lv --resizefs”
                            Will it do that so that the full 500gb would be visible and the images stored remain intact?

                              Yes! Although I am not a 100% sure the filesystem resize (to full size) will work while the system is running. Should work but I can’t promise you it will. As well just for safety reasons I always suggest for people to take a backup copy before doing these kind of operations on a production server. Should be really easy taking a snapshot in Hyper-V before going ahead.

                              The other option I was talking about would be like adding a D:\ drive and moving all the images to that new partition. As I said it’s wise on the one hand so images can’t fill up your important C:\ drive (with the database on it) but on the other side you waste free space on C:…

                                @Sebastian-Roth further info print i’ve got if this makes more sense:

                                If the system isnt running, surely I wouldnt be able to do anything, so it needs to be online?

                                  Well, you can boot into a Live Linux ISO (Ubuntu or many others) to get to a command shell and do such things with the OS on disk not running. But I think you are fine doing it live after taking a snapshot backup.

                                    @Sebastian-Roth Thanks my friend, snapshot taken in hyper-v and command run… Stupid Q now. How do I check if it’s worked 😆

                                      @RogerBrownTDL Reboot and take a look at the disk space with 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)

                                          Nice, that looks great.

                                          Marking as fixed.
