      @olivierlambert Ticket created. 🙂

      It could be a problem of the backup file. I am attempting a normal restore now to see if the full disk can be restored. Could the issue be related to NBD and multiple blocks transfer?

        I don't see why it could cause that. I'm more thinking about the BR itself.

          You mean errors on the backup server? I have no error there and have been able to read all files (cat >/dev/null) without issue. The server is using Btrfs with RAID1c3 so it verifies checksums on all reads.

            I/O error on a sector is usually due to something between your XOA and the BR. It could be many things though.

              I did further testing and found that I can reproduce the issue. While the file-restore dialogue is open, it is possible to access the files via XOA console in /tmp/<xxxx mountpoint>/, but as soon as you press "OK" the access to the disk disappears and all processes trying the mount point freeze. I reported the exact details in the ticket.

                @Forza Did you ever get to the bottom of this? I am experiencing the same issue currently.

                  No. I still have an open support ticket on this.

                    @Forza I'm also experiencing the same problem (when trying to restore a file, the machine freezes). To get out of it, I have to restart the XOA service. I'm a bit embarrassed, but did you finally get a solution from support?

                      @chr1st0ph9 Hi, I have not so far. However, I didn't test this again recently.

                        I re-checked again but the issue is unfortunately not resolved. It does not happen on all VMs and files, so maybe there is something wrong somehow in the VDI?
