      Hi,

      For unknown reason my master server crashed and I managed to restore the service by following this guide
      My VMs are working again but my XOSTOR storage is no longer working.
      Do I need to set the HA back on again before I can start using XOSTOR again with :
      xe pool-ha-enable heartbeat-sr-uuids=<UUID>

      tail -n 500 /var/log/SMlog -f return the following:

          @fred974 it looks like the logs say it cant find the controller can you confirm if it is running on any of your hosts.

          im no expert but its a start

                So we know its not running to that host as the command is targeting a single hosts uuid.

                have you run it on all your XCP-ng servers to confirm if the controller is running on any of them. perhaps check to make sure the lunstor controller is available on any host

                  @brodiecyber yes, it says 'False' on all 4x hosts. The controller isn't running on any hosts

                    ok so thats our problem the lunstor controller is not running on any node so XOSTOR has no way to initialize. Im going to do some reading and see what comes up

                      Maybe also post in the XOSTOR thread
                      A controller failure should be on the radar for possible failure scenarios.

                        also see if this script is available on the last host that has the controller which we can assume is the host that failed the first time. Maybe it has some data on why the controller isn't initializing
