      xe task-list

      Oh, that was too easy. There it is.

      uuid ( RO)                : e1896255-fbec-76d6-c2f4-9c2829c1f72b
                name-label ( RO): Async.host.power_on

      xe task-cancel uuid=e1896255-fbec-76d6-c2f4-9c2829c1f72b
      

      Doesn't cancel it.

        Okay and a toolstack restart on the master doesn't clean it?

          @olivierlambert It did now but never did before 😕

          I wonder if it is because the same host the command was run against was the master at the time and is now. Perhaps server 2 as master previously failed when the command was on server 1.

          Makes no sense to me. All good for now. Thank you.

            @olivierlambert Nope, I didn't wait long enough. It's back.

                @olivierlambert correct, which tells me it has been added again by something else. XO? Where I initated the command originally?

                  You can check who did this in the audit.log file of your master 🙂

                      This is for task destroy, not a task creation.

                        fgrep Async.host.power_on /var/log/audit.log

                          Grep on host.power_on to see if it's better.

                              It's possible that XAPI recorder the host.power_on and loop on trying to do that, but to be fair, I never saw that before 😄

                              Can you power on that host to see if it stops?

                                Going back as far as I can to audit.log.7.gz only takes me back to June 30 and this has been a problem for more than a month so I don't think I can find the original request.

                                  I had the whole rack powered off yesterday, 2 - XCP-NG 8.1 servers (DL380 Gen9), 1 Freenas (DL380 Gen9) for iSCSI VDIs. It still came back.

                                      Yes, everything is up and working, just the task appears in XO and also on the master's tasks list as we see.

                                        Weird. Can you disconnect XO from this pool, restart toolstack on master, and see if the task is popping again? I think it will, I don't see why XO would do that.

                                          I would remove the hosts from XO, restart toolstack, add hosts back to XO? Is this correct?

                                            Don't add host back in XO for few minutes, and check if xe task-list got the task appearing without any XO connection.
