      Yes, VDIs connected to a VM are by definition not orphaned. You don't want to remove those.

        just out of interest when i change the magnifying glass to "type:VDI-unmanaged"

        it lists "base copy"

        what are they?

          They are the read only parent of a disk (when you do a snapshot, in fact it creates 3 disks: the base copy in read only, the new active disk and the snapshot).

          If you remove the snapshot, then a coalesce will appear, to merge the active disk within the base copy, and get back to the initial state: 1 disk only.

                1. Please edit your post and use Markdown syntax for code/error blocks
                2. Rescan your SR and try again, at worst remove everything you can, leave it a while to coalesce and wait before trying to remove it again

                    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

                        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?

                                      @robert-wild I'm not sure about that. See this comment https://github.com/xcp-ng/xcp/issues/104#issuecomment-449381556

                                        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.
