    Hey guys,
    I cannot login to my FOG server. I get to the login screen and i type in my password and it acts like its logging in but just goes back to login screen. The other day I went to check on the FOG server, cause I haven’t used it in a few months, and I couldn’t get anything on my monitor. Everything was hooked up as I had not touch it since I had everything working the last time I used it. I did a hard reboot and it came up, but had some error that was too quick to take a pic of. I rebooted again to a previously good date and it worked fine. I logged in and updated everything without a hitch. I started a test image, just to make sure all was good, and in the middle of capturing this happened.

    I looked over at my server and saw this.

    Come to find out my NAS was powered down for some reason. So I turned it back on, rebooted my server and that’s when I got the login loop.
    Hope this info helps. Let me know if you need any more info. Thanks.

      @ManofValor Seeing as /images (or whatever your relevant storage point is) is expected to be on the NAS, I’d recommend cleaning out the current storage location as it’s located on your main disk. You could just do something like:

      Unmount the current NAS if it is already mounted with:

      umount /images
      

      Then check the /images directory and remove any files in there. This is entirely up to you at this point, I’m giving you how to fix, make sure you don’t delete all your current NAS images.

      rm -rf /images/*
      

      Then try to mount the nas.

      Please help us build the FOG community with everyone involved.

        so, login loop for the web interface, or for logging into CentOS 6 ?

              I can do that. Everything seems normal from the command line.

                @ManofValor You need to check things. Seems and is are two different things. The first thing to check is free disk space.

                  Try logging into text mode with root account. when this happens to me, I can only log in with the root account and locally, because root login with ssh is disabled in our environment.

                    I think turning the NAS back on will have fixed the disk space issue cause I haven’t done but a couple images since I got it going. Here is the df output.

                      @ManofValor Your root partition is 100% full. That’s the problem.

                            @ManofValor because your /home is at the same place at your / and when you try to login, some files maybe touched and this prevent you to enter.

                                @ManofValor Seeing as /images (or whatever your relevant storage point is) is expected to be on the NAS, I’d recommend cleaning out the current storage location as it’s located on your main disk. You could just do something like:

                                Unmount the current NAS if it is already mounted with:

                                umount /images
                                

                                Then check the /images directory and remove any files in there. This is entirely up to you at this point, I’m giving you how to fix, make sure you don’t delete all your current NAS images.

                                rm -rf /images/*
                                

                                Then try to mount the nas.

                                  @Tom-Elliott Very good thinking, Tom. If the NAS was off, mounting failed, and any images you captured would have gone straight onto the root partition. ESPECIALLY since I remember ManOfValor running the installer so many times before having the NAS correctly configured, the needed .mntcheck files and dev folder would absolutely be present, so any upload would go until space ran out.

                                  @ManofValor Try Tom’s advice - but you must be careful, you MUST successfully unmount the /images directory for the NAS, and you SHOULD confirm and reconfirm that it unmounted correctly. Being new to linux, after this command I’d even suggest you turn the NAS off after unmounting. Then run the delete commands that Tom posted. Then run df -h to check free space. If the root partition is substantially free’d up, then hook everything back up, turn it on, give the server a reboot, and see if things work.

                                  Tom’s commands would also ensure that uploading will never work without the NAS being properly mounted - unless of course you run the installer without the NAS being mounted, as the installer would re-create those needed files/folders for image capture on the root partition.

                                  Let us know how it goes.

                                    Also, the problem was found, but it’s not solved yet, so I marked the thread unsolved. I don’t want others to not bother reading & helping because they think it’s solved.

                                      Good morning,
                                      Everything on the NAS is just tests, so if I don’t care what’s deleted then I don’t need to unmount, right?

                                        @ManofValor You would still need to unmount, because the space is used by your main system. Simply removing all the data in the mounted partition will only free up space on the mount point.
