    @cmanos No problem, glad I could helped. As Olivier also pointed above, it's not an issue anymore when using QCOW2 which is currently in beta, so hopefully it's only a short workaround

    interesting can you try to do a perfomance test while using block storage ? [image: 1762419476977-81709355-5c09-4581-a424-9245a367bbdb-image.png] This will store backup are multiple small ( typically 1MB ) files , that are easy to deduplicated, and the merge process will be moving / deleting files instead of modifying one big monolithic file per disk. It could sidestep the hydratation process. This is the mode by default on S3 / azure, and will probably be the mode by default everywhere in the future, given its advantages (Note for later : don't use XO encryption at rest if you need dedup, since even the same block encrypted twice will give different results)

    Yes, they are created either: on demand for users when we need in XO 6 Now, XO 6 is becoming the main driver for new endpoint as the UI is providing more and more features.

  • Terraform, Packer or any tool to do IaC

    This approach isn’t entirely foolproof since I can’t use a wildcard, and I don’t know how many disks will be attached to the VM. For now, it will never exceed two disks, so I can explicitly include both in the ignore_changes statement. That’s an acceptable solution for us. Thanks for your support.

    @florent Limiting concurrency did not fix my S3 backup problem, but it's working again after updating the build. So I guess it's resolved.

    You should probably be able to fix this issue by installing the ntfs-3g package. As you mentioned you're running it on a Synology, you can do that in DSM by opening Docker -> Container -> Select your container -> Details -> Terminal and enter the below in the console. apk update apk add ntfs-3g Let us know if it helped.

    @olivierlambert Well, for now, I'm mostly playing around with this tech to teach myself about it, gaining experience and coming up with ideas. Maybe someday I'll be able to return some profit with the business I'm building / trying to figure out (hosting game servers). Then I'll sign up for some Pro support - and maybe then we can work on the concept of HA XO I understand what you're saying. I think I can come up with a good enough way of achieving the HA I'm looking for. Anyway, thanks for takning the time to respond. I understand your schedule is busy.

    If you use XOA, I would strongly suggest to open a support ticket. This way, we can investigate properly on your XOA and see what's going on.

    Weird Issue with NFS and Synology Hyper Backup

    It's important to understand the components you are using, especially on a software that you use without support/training In short: SR: a Storage Repository is access by your host/dom0/XCP-ng, and will be used to store ISOs and/or VM disks. It's running on a relatively old CentOS release (7.x), and will mount with some specific settings BR/remote: a Backup Repository where Xen Orchestra will send the backup of your VMs. Usually, Xen Orchestra runs (in XOA) inside a Debian 11 VM, with default NFS mount options (default: ie from the operating system point of view). It's hard to tell exactly the issue since you are likely using XO from the sources, so a XO that you choose to install on a system where we (aka "XO devs") have precisely 0 control on. Plus the NFS configuration part is also out our scope because it's not running inside our infrastructure too. That's a lot of moving pieces, that's why it's important to understand what you do so we can assist here the most efficient way we can

    There’s usually little to no reasons to expose any mgmt systems to internet in actual production environments. Especially if it’s strictly for internal mgmt purposes. XO is no exception. Not because the system would be unsecure, but you simply want to make any attack surface as small as possible. It’s just a best a practice.

    @olivierlambert said in Orchestra 5.61.0 VM Doesn't Auto-Start in XCP-ng 8.2: Try to disable/re-enable autostart then. Hi, I had this trouble, on XCP 8.2 / XOA agent 7.4.50-1, the Olivier's advice fixe the problem.

    @ronivay Ok. In between jobs I did a new VM install of debian 11 and on it the XO community version. Version numbers now: xo-server 5.100.1 xo-web 5.101.1 I seem to have everything working again. Thanks for the help and tip. Now it seems really solved. If I come across anything else, which I don't think I will, I will report back. Greetings and thanks, Jan

    @Forza Hey - thanks for the input. It would be valid if I would reboot xcp host though. All this is happening on live xcp server which is problematic. It's no the end of the world but there has to be a way to debug it. Any tips on that?
