            We need to see the Xen logs, too. Those are the logs with "xen" in the name.

              @scottalanmiller said in XenServer 6.2 servers down. I have no Xen skill. Most likely networking? Help!:

              I can't upload the .gz to here. Can I open the contents in wordpad? Sorry if I missed something.

                  It ate my text. How do I display the logs to you? Sorry. A lot of new knowledge in a short period of time, combined with stress.

                      Sorry, ate my text again. Unless I should be looking somewhere else...

                        Is there any way to tell why the hosts can't even attach to their own local storage, or why it was unplugged in the first place?

                          Get us the SMlog tail...

                          tail -n 100 SMlog

                                  @CitrixNewbJD okay, no need to look in the xen folder, that's not going to be a useful log 🙂

                                    I'm discussing conversion options with Scale. Looks like moving the disk images over would not be too hard as long as you can pull them off of the SAN.

                                      If you do this...

                                      cd ..

                                      It will take you back to the main logs. What is the output of this...

                                      ls | grep -i xen

                                        While you are working on that, this is a good time to discuss triage. In all honesty, this is an old, unmaintained cluster. What is the hardware of the compute nodes?

                                        The storage is poor. Even if we fix things, the system is very old in both software and hardware. So it's only a bandaid. Which is very doable, but it is what it is.

                                        Doing a migration, like right now, might be the logical path forward. Let's get your specs for the current cluster, concerns for a new one and discuss if that's a real possibility. Also, what is the moment to moment impact of the outage?
