          In general, if you have an issue, the first thing to do is to rebuild on latest master commit and try again. If it persists, then it's a non-fixed bug 🙂

          Also, if you are in production, we strongly recommend to go with XO support!

              Seems pretty self explanatory to me. If that isn't the case, then you'll need to provide additional details.

                  @x-rayd Have you checked source SR to see if it is running low on disk space?

                      Coalesce after snapshot removal (or VDI removal you did), some space we reclaimed automatically.

                      It was a lack of space on destination SR, your DF Equallogic, probably using thick provisioned.

                        my Equallogic have 12TB space and only 4.5 TB space is used from continuous replication backup!xoa3.jpg

                          So? As a thick pro SR, every first snapshot will double space needed on the disk size (not space used, total disk size). If you have 4x 2TiB VM disks, a single snapshot of those won't fit.

                            you mean DF Equallogic have not much space?

                              I mean double check source and destination SRs free space.

                                  If you have 3 VMs that each have a 5TiB disk and you want to back up all of them you need at least 3x5=15TiB on the SR for the initial snapshots. Then you also need some extra GiBs or TiBs for the deltas.

                                  The workaround is to set up the SR as EXT, instead of LVM.
                                  Then it's using thin provisioning, meaning that the snapshot only uses as much space as you have data in each 5TiB disk.
                                  So if your VMs are only using 1,3 and 4 TiB of actual disk space then you only need an SR that's 1+3+4=8 TiB + the extra space for the deltas.

                                        If you get to this point, it means you are doing snapshots outside Xen Orchestra

                                            Next problem!
                                            After each backup locale storage have empty disks. Why?
                                            If delete this disks, comming after backup renewed.
