        xe vm-disk-list vm=(name or UUID)

        im going to cross refernce it with this

        xe vdi-list sr-uuid=$sr_uuid params=uuid managed=true

        and any vdis that dont match im going to delete with

        xe vdi-destroy

        is this corect?

            It's not XOA that's not working. XO is the client, sending commands to the host. You had a pretty clear error coming from the host, so the issue is there.

            Also, please edit your post and use Markdown syntax please, otherwise it's hard to read.

                Why? How it's related? Have you cleaned the maximum number of VDIs?

                            so i know my continous backup replicas arnt happening because it cant do a coalesce any of my VDI's

                            WARNING: Failed to connect to lvmetad

                            so if i run this command in my xen server 7.6

                            vgchange -a y --config global{metadata_read_only=0}

                            the next time my xen server does an auto coalesce any of my VDI's, will it become good again?

                              think i have answered my own question -

                              https://support.citrix.com/article/CTX207574?_ga=2.182110311.1347118359.1579810336-430666083.1579810336

                              basically dom0 is protecting the source vdi until vbd operations complete but theres nothing to complete

                              you think this is worth a shot

                                This is already something visible in Xen Orchestra, in Dashboard/Health view, we exposed all VDI attached to a control domain, it's one click to solve it.

                                  so its still attached to my DOM0 ie xenserver the host itself

                                    You need to unplug before remove it. XO does that automatically.

                                      thanks Olivier,

                                      i thought while im having this nightmare i mightaswell update my XOA at the same time

                                      so if XOA auto unplugs the vbd to the vdi, why is it throwing errors?

                                        This is a message for XO team, it should do that normally.

                                          its still there ie the host is still atached to that vdi

                                          im thinking this is the issue why my backups wont run anymore

                                          if not i will do it on the xen server cli, but it would be nice to know why this isnt working
