      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.

                          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
