      Having an issue with XCPNG Center and my xen servers SR_BACKEND_FAILURE_109. It says the snapshot chain is too long. I have read that we are probably making backups faster than XenServer can coalesce. I have attempted to force it to coalesce, but at the moment I have had no luck.

      Anyone have any suggestions?

        Hi,

        Yes, reviewing SMlog to understand why it's not coalescing. Or is it? Not enough space?

          This is a copy of the varlog I believe. I am relatively new at this and was thrown into a pit of wolves basically.

              It's for your homelab, right? However, I have the feeling it's not. Don't tell me you have this issue in a production environment 😆

                Well unfortunately the previous guy put in a production environment. He left now I'm cleaning up his messes. So yes it is in a production environment I am currently trying to resolve the issues that were created by him.

                  Ouch. And I suppose there's no pro support for this production environment?

                    Not that I am aware of. We have support individual VMs because they have paid software on them, but we don't have support on the VM manager itself.

                      While we'll try to help, that would be a good time to tell people who write the checks to think about supporting this critical part of the infrastructure 😉

                      Please provide the entire SMlog so we can take a look.

                        @ntinthomas I fixed your post above so that the log displays correctly. Please follow the below example in the future --

                        ```
log goes here
```

                                In XO: SR view, click on the SR, advanced. Can you share a screenshot here?

                                Also, do you have VMs with a lot of snapshots?

                                  This is the screen i generally see and work from. And yes we have about 13 VM's with screenshots being sent to a FreeNas box.

                                    XCP-ng center isn't an officially supported client, and worse than that, it doesn't expose the number of disks left to coalesce, unlike XO.

                                    Also, you are on 8.1, which is EOL 🙂

                                      So what would be the best solution to get this resolved?

                                        Do you have a lot of snapshots in your VMs?

                                        Having an XOA deployed would help to diagnose too.

                                          So we had them scheduled to take snapshots every night of every VM. I noticed that errors were accumulating this week. How would I deploy XOA to help diagnose the issue?
