        This is for task destroy, not a task creation.

          @olivierlambert it is all I see from:

          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.

                      So now everything is back online but despite that you got the task?

                        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.

                                Host #2 has been powered off during these checks. I will power it on so that all pool members are available and try xe task-cancel again. Then proceed with your suggestion. Standby.

                                  OK this is interesting (host1 is master). I powered on host2 and ... the task disappeared from xe task-list and XO Tasks.

                                  I powered off host2 again and the task is back.

                                    I am powering up host2 again only to remove it from XO and follow your direction.

                                      Both servers are running in the pool.
                                      Both removed from XO.
                                      Toolstack restarted on both servers via XCP-NG Center at 12:50pm local time.
                                      Server communications re-established automatically in XCP-NG Center at 12:52pm.
                                      Pool master added and 2nd server added to XO at 12:54pm.
                                      No tasks are listed on either server with xe task-list.
                                      No tasks are listed in the XO UI.
                                      Powered off server 2 from the server's console screen (not XCP-NG Center or XO being the point).

                                      I have a task in the master on the CLI and XO again.

                                        @dsiminiuk You should only be adding the pool master in XO, not the slaves.

                                          http://xo/#/settings/servers is only for the pool masters not pool members?

                                          I don't see where it says to not add pool members other than the master
                                          https://xen-orchestra.com/docs/manage_infrastructure.html#home-view

                                          I am grateful for the help but it didn't solve this issue. The task is back.

                                            Quoting the doc:

                                            Add a host
                                            Just click on "Add server", enter the IP of a XenServer host (ideally the pool master if in a pool)

                                            So yes, in a pool, only the master is needed to connect to all machines.
