              @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:

                XCP-ng 8.3 up to date,

                      @Gheppy It's not clear to me. Is it fixed on latest commit on master as of now?

                        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

                              @Gheppy if this is what I think it should have been fixed by https://github.com/vatesfr/xen-orchestra/commit/3c8efb4dc3e1cb3955521063047227849cfb6ed3
