      And moments after that last post, Robinwood fell off…

      I expect them all to be not-reporting in the morning if the issue is consistent.

        The main and one of the nodes I checked does not have mod_evasive installed.

          Any ideas on this?

              I rebooted that particular Storage Node. For the moment, it appears to be reporting its version correctly. I expect it to quit again after some time passes.

                Update on this.

                The two storage nodes I’ve rebooted are sticking around with version reporting… Man this is weird.

                I guess now the next step is to reboot them all and see what happens.

                  I checked the nodes version reporting and interface reporting this morning - it’s still working.

                  So - I have no idea why but - the moral of the story is if you change your fogstorage password on the main database, after changing the snmysqlpass field in /opt/fog/.fogsettings on each node and re-running the installer, reboot the node.

                    I spoke too soon.

                    They are all not reporting again. Considering - they stayed reporting all night long into the morning before anyone got here - this must be load related somehow.

                      I wrote a script that reboots them all, and ran that. They are all now reporting again…

                      This wasn’t an issue until I changed the password for fogstorage - Why would that cause this?

                        Below is the apache error log from one of the nodes, snipped from when the server rebooted to when the issue happened again. The server operated for exactly 37 minutes before falling off again. All storage nodes fell off at the same time - since they were all rebooted at the same time.

                          Found a blurb about this error on Stack Overflow:

                          http://stackoverflow.com/questions/14748499/fatal-error-too-many-open-files

                          Quote:

                          Don’t store DirectoryIterator objects for later; you will get an error saying “too many open files” when you store more than the operating system limit (usually 256 or 1024).

                          For example, this will yield an error if the directory has too many files:

                          <?php 
                          $files = array(); 
                          foreach (new DirectoryIterator('myDir') as $file) { 
                              $files[] = $file; 
                          } 
                          ?>
                          

                          Presumably, this approach is memory intensive as well.

                              I’ve found this site that shows how to set new limits properly on Ubuntu.

                              https://www.drupal.org/node/474152

                              I’ve converted the commands for CentOS 7/Fedora/RHEL - and made it into an SSH command ran against a remote server.

                              ssh aifog "echo 'apache soft nofile 1600' >> /etc/security/limits.conf;echo 'apache hard nofile 65535' >> /etc/security/limits.conf;systemctl restart httpd"

                              Note that the above is an ssh command that uses aliases and pki-based certificates - that my project called ssh-pki-setup has already established for me. That command executes the commands in double quotes against the remote server, and it successfully added the options to the remote server’s file and restarts httpd.

                              If successful, I’ll do this for all storage nodes - and post commands that can be ran manually too if you don’t have so many servers to manage as I do and prefer manual.

                                After the last reboot - all storage nodes are still reporting. But I assume they will eventually fail. I’m just waiting for that to happen - to see if the one I modified hangs in there.

                                In the mean time, I’ve been watching the number of files open by apache with this command I put together: lsof -l -u apache | wc -l

                                Open files have been steadily growing:

                                [root@wgfog ~]# lsof -u apache | wc -l

                                  Ok, the node I’ve been monitoring open files on - just fell off.

                                  And - the magical limit is… 8006 files open by Apache - causes everything to just stop.

                                  And… the one storage node I modified… it stopped reporting too… 😞

                                    This article seems relevant but I don’t see how it could help in the case of FOG. https://httpd.apache.org/docs/current/vhosts/fd-limits.html

                                      I think this must be a file descriptors leak in the storage node configuration.

                                      I’m going to patch it myself after lunch.

                                        It would also appear that Apache is upping the file descriptors limits as it can - but it just can’t keep up, because there are so many files getting opened so fast, and not closed.

                                        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!

                                          Figured out the bandwidth monitor is the primary file that’s getting so many calls. bandwidth.php

                                          Currently hunting down every place where it’s used - including it’s define line in config.class.php called STORAGE_BANDWIDTHPATH
