    I have rolled back the passwords and now back to: Updating Database failed! Failed to open stream: no such file or directory

    However, I can actually Capture to the master fog node, just not to the separate node!

    Must be permissions I think?

      Never seen this error before but searching the web I found this on stackoverflow. Without having more details I cannot see where exactly it fails. So please take a look at the apache and fpm error log on your storage node and post here. See my signature on where to find those logs.

      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)

          @Kevin-Talbot Have you checked the error logs as suggested?

          Rereading your initial post I noticed that you say you moved to a different subnet as well. Meaning IPs of master and storage node have changed as well?

          Check all the IPs you have in /var/www/html/fog/lib/fog/config.class.php and /opt/fog/.fogsettings

          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)

            @Kevin-Talbot This thread is almost 1 month old. I take it, its still an issue?

            Can you take a clear screen shot of the error so we can see the context of the error? It sounds like the linux user fog’s account password was changed/is out of sync with the webui. I have a tutorial on how to get everything back in alignment here: https://forums.fogproject.org/topic/11203/resyncing-fog-s-service-account-password

            The fog service account should exist on the fog master node the storage node should have their own service account too.

            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!

              I can deploy from and capture to the master fog server perfectly fine.

                Thanks for the reply Sebastian!

                Only the node subnet has changed, I re-ip’d it as per the book!

                  You can’t normally capture to a storage node. Only the master node in a storage group can be used to capture images. I just want to make sure we are on the same page here.

                    node. Only the master node in a storage group can be used to capture im

                    I’ve always captured to a node, I have a separate storage group with one node in it which is the master for that storage group!

                    But I think you may have just nailed the problem…when I moved the node I renamed it and re-ip’d it and something tells me I may have deleted the old “named” node and added the newly “named” node but not clicked “master”

                        @Kevin-Talbot I just made the node a master but that has not cured the problem!

                                @Kevin-Talbot your image didn’t upload but lets try this.

                                In the storage node definition for the remote storage node in question. There is a management user account and password. From your windows computer, can you ftp to that remote storage node using those credentials? Those credentials should match the contents of the /opt/fog/.fogsettings on the remote storage node.

                                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!

                                  @george1421 Yes I can FTP with Filezilla to the node using “fog” and the very long generated password!

                                  The DEV folder has the images under folders named by the mac addresses as it should do but clearly cannot rename and move them to the IMAGES folder?

                                        @Kevin-Talbot OK let make sure we understand a few things (building a truth table).

                                        1. The storage node in question is 172.16.220.246?
                                        2. You were able to ftp to that storage node using the user name of fog and that long password from storage node page?
                                        3. The image is arriving on the 172.16.220.246 server in /images/dev/<mac_address> directory?
                                        4. We see the failed to update database message
                                        5. The actions were it failed are in the FTP section of the code.

                                        Here is where I’m going:

                                        1. What does the permissions look like on the /images and /images/dev directory?
                                        2. Does the linux user fog have rights to move/create files?
                                        3. Do the permissions on these directories match the FOG Master Server’s directories?

                                        I believe where the process is falling down is when the target computer connects to the fog server (node) using FTP. At this point it needs to move the images from /images/dev/<mac_address> to /images/<image_name>. It should do that with the ftp mv command. One should be able to do the same steps from a FTP client connected to the remote storage node.

                                        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!
