      Hello,
      I have problems with continuous replication, meaning that if I choose to do it on a single SR everything is ok but if I add two or more SRs it crashes and gives the error message below.
      The problem is that it does nothing, it stays stuck and it is always the first SR in the list.
      Info:

      • XCP-ng 8.3 up to date,
      • XOCE commit 6ecab

      Here it is with only one SR and everything is ok:

      • configuration:

      • transfer:

      Here it is with two SRs

                    @Gheppy it's always easier to fix when we can build a minimal setup that reproduce the issue
                    thanks for your report

                      Hello, the problem has reappeared.
                      This time with a different behavior.
                      It hangs at this stage, and the export tasks do not even start/show.

                      Info:

                              I update to last commit, two more change is on git now

                              d1aff2fd-b61f-45fa-a375-6155ee9bfc60-image.png

                              The problem still exists. From what I've noticed, export tasks start being created and then disappear shortly after. And then a few moments later the import tasks appear and it remains blocked like this.

                              42647e87-a3ae-451c-9001-555b3ad26bf8-image.png

                              Only up to this commit 7994fc52c31821c2ad482471319551ee00dc1472 (inclusive) , everything is ok.

                              EDIT: I read on the forum about similar problems. I don't have NBD enabled.

                                  I will update to the latest version and look at the logs.
                                  Now I have version 7994fc52c31821c2ad482471319551ee00dc1472

                                          hmm,
                                          I found the solution, after I read here on forum.
                                          I enable this options and save and then disable and save and now is ok. Task is running again. It is running with last commit to
                                          So the problem is with these settings which may not exist in the task created before the update.
                                          05b77f69-6e87-49d2-9c62-d795a13d161a-image.png
