      @Andrew Yes, I'm working on this and should have something to test tomorrow 🙂

        @Andrew @Gheppy, I have something new test, it's an important change concerning a low-level component of XO, hopefully I did not break anything 🤞

        The cr-issue branch has been rebased, make sure to reset it properly, re-install dependencies and rebuild:

        cd xen-orchestra/
        git checkout cr-issue
        git fetch
        git reset --hard origin/cr-issue
        yarn
        yarn build
        

        Let me know if you have any issues 🙂

            @julien-f Broken. Job failed. Lots of Error: Premature close. Data not replicated.

            Job report: job.txt (text format)

            Journal XO output: out.txt.gz (GZ format).

                I still don't understand exactly the issue, not sure if it comes from XO or XCP-ng/XenServer, but latest version does integrate a work-around, if you encounter Premature close error during CR, you can add the following to your xo-server's configuration file (usually /etc/xo-server/config.toml) :

                [xapiOptions]
                ignorePrematureClose = true
                

                It's not enabled by default until completely understand the root cause and it's properly fixed.

                @Gheppy Thanks a lot for your tests and feedbacks 🙂

                @Andrew Thank you very much for the test appliance, it was an invaluable help investigating this. If you can keep it online for the time being I'll probably have further tests to do with it next week 🙏

                  @julien-f I updated XO Source to current master and added the new ignorePrematureClose=true option. Backup ran the CR correctly again.

                  Yes, I can leave the XOA test tunnel up for testing. I'm happy to help you help me!

                    @Andrew do you still have the issue without the ignorePrematureClose?

                      @olivierlambert Yes. Still problems on the new code without the option set. 90% of the VMs fail 10% finish correctly on CR.

                          Just for info
                          I installed the latest version of XOCE, commit 083db67df9e1645a2f8fe2fac564b3aecf30d55e
                          CR is ok and can be used in case of disaster, with ignorePrematureClose = true.
                          I managed to start the VM without problems, the VM itself ( that is the CR copy ) .
                          At the moment I have a very slow copy problem of the VM that is created with CR on the seccond server ( 18Mb max ), the problem is that the same connection goes with 400Mb for a CR copy. I want to make a copy of VM-CR and start it

                              You need to add this on config file.
                              Location for me is /opt/xen-orchestra/packages/xo-server/.xo-server.toml

                              [xapiOptions]
                              ignorePrematureClose = true

                                @Gheppy Yes.. putting that in place seemed to fix DR.. but not CR.

                                  🤔 Any log or something @magicker ? Are you sure it's a CR started after modifying the config and restarting xo-server?

                                      @olivierlambert spoke too soon.. CR works in one direction but not the other

                                        @magicker Any differences between the two hosts? XCP-ng versions maybe?

                                          Jumping in as another "victim"... I have lost almost all ability to run any kinds of backups.

                                          System information:

                                          XO from Sources
                                          XO-Server: 5.109.0
                                          XO-Web: 5.111.0
                                          Commit: d4bbf

                                          I had no issues running any kinds of backups prior to applying the latest commits two weeks ago, Monday, February 6, 2023. After applying that commit, everything seemed to be OK until late that evening. At that time, one of my CR jobs started and never completed. All of the subsequent jobs failed, of course, because another job was already running. I was able to delete the job and restarted the toolstacks and rebuilt a new job. This started to spread until, eventually, all of my CR jobs would fail. That issue has now spread and my DR jobs are now failing, too. Out of the seven backup jobs that were working with no issues prior to that date, I am now only able to run one job successfully, and that is a DR job.

                                          The DR and CR jobs are written to different repositories (the CR jobs are written to the storage repository on one of the other XCP-ng servers and the DR jobs are written to an NFS share).

                                          I tried running the cr-issue branch update that @julien-f recommended, and modified my config.toml file with the ignorePrematureClose = true code that was also recommended. Nothing works.

                                          If I try to run a DR job now, even a brand-new one, it looks like it wants to start and create the snapshot, but then fails and actually shows it will start in 53.086 years.

                                          Anything I can get, just let me know what to pull and I'll add it here... hopefully that will help. Right now, I'm able to only back up a single VM!
