      @julien-f Ok....thanks Olivier and Julien. Changing that setting in that way had no effect on the issue. You have any idea what would cause this from one version to the other. XCP-ng is version 7.5 with a second local storage repository.

        Hello,
        I experience this problem with CR job. xo-server 5.51.1
        I revent xo-server 5.50.1. No problem with this version.

        I found these errors in xensource.log. maybe not related:

        Importing raw VDI R:55902cfbe5b0|vhd_tool_wrapper] vhd-tool failed, returning VDI_IO_ERROR
        vhd-tool output: vhd-tool: Non-zero size required (either a pre-existing destination file or specified via --destination-size on the command line)
        

        and this:

        xapi: [error|XenServer-08|12899 INET :::80|Importing raw VDI R:55902cfbe5b0|import] Caught exception: VDI_IO_ERROR: [ Device I/O errors ]

          Could this be related to this: https://github.com/vatesfr/xen-orchestra/issues/4640?

          BluejacketScott created this issue in vatesfr/xen-orchestra

          closed XO From source restore backup fails with VDI_IO_ERROR #4640

              @txsastre I'm taking snapshot of XO vm before every update. Simple revent it.

              Because it is from source so I have no support subscription. I recommend this to you.

                @rizaemet-0 thanks you've got the right. I already doing this, but I didn't know if you uninstalled it and installed a previous version.

                it was just curiosity. So I'm gonna rollback to a previous snapshot too.

                Thank you

                    @Danp thanks ! but I have rolled back to a previous version ( 5.50.1) and now I'm testing the backup again.

                      Can any comment on the fact that all of these issues are caused because 'import_raw_vdi' doesn't support Chunked transfers?

                      This used to be fine casuse the loophole that allowed a massive Content-Length has been closed.

                      known. This depends on a corresponding change in the ocaml-vhd library.

                        I saw this note relating to ZFS: It is not yet possible to import, migrate or export a VDI to/from a ZFS SR

                        Could that be why my continuous replication is failing? I'm trying to replicate from one ZFS SR to another on a different server.

                          No, since few release, ZFS should support all operations.

                            That's too bad. I don't see where anyone really had any solution.

                              Your CR issue might be related to a XO bug on master, not too a XCP-ng issue 😉
