        @tgidwani Please as well run grep USERNAME /var/www/html/fog/lib/fog/config.class.php and post results here.

        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)

            with CentOS 7

            Why didn’t I see this any earlier?!??!

            Please run command getenforce on your FOG server and post output here.

              @Sebastian-Roth I followed all the steps in the mentioned article when setting up my CentOS 7 VM and before installing FOG.

              Here is the screenshot:

              selinux-status.PNG

              When I got the update database failure, I disabled and stopped firewalld and set selinux=disabled in /etc/selinux/config and restarted my CentOS 7 VM. Re-ran the capture process but still continued to get the same failure of updating database.

                @tgidwani Seems like we need to work this out manually. Use a ftp command line utility (Windows or Linux) and connect to the FOG server using the credentials you see in /var/www/html/fog/lib/fog/config.class.php.

                Try connecting, then create and rename a directory just to see if things work like expected:

                shell> ftp 192.168.2.5
                Connected to 192.168.2.5.
                220 (vsFTPd 3.0.3)

                ftp> pwd
                257 "/home/fogproject" is the current directory
                ftp> cd /images/dev
                250 Directory successfully changed.
                ftp> mkdir test12345
                257 "/images/dev/test12345" created
                ftp> rename test12345 12345test
                350 Ready for RNTO.

                221 Goodbye.

                    @tgidwani Alright, FTP is not an issue I am fairly sure now. Seems like I was miss-lead by the messages we saw in the php-fpm log file. Those probably came from the time before you disabled SELinux… I reckon.

                    So do you still see it failing on database update at the end of the task?

                    Please check the log files again but this time only take a look at the last 10 lines: tail -10 /var/log/php-fpm/www-error.log

                      @Sebastian-Roth I cleared all three error log files today before posting the screenshots here. With or without SeLinux disabled I keep getting the same failed to update database error.

                        Don’t you get new log entries when doing a new capture? There is no possible way we can help you without getting more evidence on what exactly is causing this. Logs are usually the best way to figure this out.

                          @Sebastian-Roth My apologizes for the confusion. I meant I cleared them only today to eliminate the possibility of looking at stale logs entries.

                          I do get new log entries every time I run a capture. I continue getting the same error every time. Update database failed with the same ftp_put failure. Would you like me to re-run the capture? Since I have not changed anything I am not why the problem would go away?

                          Do you think it is a version issue? I am running 1.5.6? Does updating the database process depend upon DNS or a default gateway by chance?

                            @tgidwani Ahhh, I see, got that wrong, sorry. I will take a look at our code again to see if I can figure out what might be causing this.

                            Just to be sure, Do you still get the full list of exact same ftp_… messages in the log everytime even when SELinux is disabled/permissive?

                              @tgidwani Looking at out code more closely I noticed that most of those ftp_... warnings are perfectly fine. FTP is not able to remove a directory that isn’t empty yet. So we do some kind of recursive delete which leads to print out all of the “ftp_delete” and “ftp_rmdir” messages which are not important. I’ll still remove those in the next release we get less confusion.

                              But the “ftp_rename” and “ftp_put” warnings make me think there is something wrong with your NFS shares. Just guessing here but let’s give it a try. Please run exportfs -v as root on your FOG server and post output here. As well take a picture of the Storage Node setting in the web UI and post a picture here.

                                    @tgidwani Ok, lets try to focus on the following warning in the logs: ftp_put(/images/dev/ac1f6bb0690e): failed to open stream: No such file or directory

                                    What FOG does is it boots the FOS (FOG operating system) on the clients and mounts /images/dev directory (NFS export) to write the new captured image into /images/dev/<MAC-ADDRESS> - in your case the client MAC should be AC:1F:6B:B0:69:0E - please double check just to make sure there is no culprit in this. Now after the image capture is finished FOS calls back to the FOG server and tells it to move that newly captured image from /images/dev/<MAC-ADDRESS> to /images/<IMAGE-NAME> and this is exactly the point where things seem to fail for you.

                                    Thinks to check:

                                    • When capturing an image, do you see files being written to /images/dev/ac1f6bb0690e -> if not we need to figure out why!!
                                    • When the capture is finished, do you still have those files in place? They should still be there if rename/move failed. -> Then try to rename/move those manually via FTP to hopefully see why it fails. Connect via FTP as below and run: rename /images/dev/ac1f6bb0690e /images/Imagename

                                      @Sebastian-Roth When I was experiencing said error the intermediary directory was never being created.

                                      It is working now. As mentioned in my previous reply asking about the default gateway, I think it has something to do with the Gateway configured in my network interface’s configuration file.

                                      Within the config file, GATEWAY= was pointing to an IP address that was not assigned to any machine on the current network when I moved networks. When I removed the GATEWAY= line from the config and ifdown and ifup my network interface, the update database error was resolved.

                                      Does FOS when communicating with the FOG server go through the default gateway even when both the client running FOS and the FOG server are on the same network?

                                        @tgidwani Wow. Really glad you figured that out. I have done a lot of networking but I wouldn’t have expected the gateway setting to cause such an error. In theory the gateway information is only ever used when the host tries to connect to a machine that is not within it’s own subnet. So gateway shouldn’t play a role here as long as both were in the same subnet.

                                        Are you able to replicate the issue when putting the GATEWAY= line back into the config??
