      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:

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

        BluejacketScott created this issue in vatesfr/xen-orchestra

            @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.

                    XSI-19 locate VHD footer based on file size

I order to locate the footer in a VHD file or stream, the total length
of that file or stream must be known. This commit passes it when it is
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 😉
