            We don't have other reports of failed restore on LVM, so it slipped out of the radar.

            Ideally, a support ticket might be better to keep it in the TODO πŸ™‚

                XFS? That might be the reason why, I don't remember that we support XFS for file level restore.

                    @badrAZ or someone else of XO team will try to reproduce the issue. They are under heavy lot for a bunch of new exciting features, so it might take time to test.

                            I tested this functionality on ext4 and xfs and it works for me.

                            Unfortunately, i need to reproduce this issue in our lab to be able to investigate more.

                                  @othmar Install XOA in trial mode and then retest to see if the issue is present with it.

                                      It's same here. Problem is in community version and in xoa trial.

                                        There's obviously something different between the VMs you use and ours for tests. Would you be able to provide a VM export so we can deploy it on our side, backup it and see why file restore doesn't work?

                                            Do you have a VG using multiple PVs?
