    In case anyone wonders how this played out. At the end of the day, I shutdown the host with the running workloads on it, kept it at BIOS boot so the 8.3 installer would upgrade it cleanly, and then booted it back up. For reasons related to my particular setup, the down time was more than 60 minutes. But that's not related to XCP-ng. The XCP-ng installer was maybe 10 of that. 20 of that was 3 reboots on a server that takes ages to boot. One thing that is a bit difficult is that the 8.3 installer doesn't notice ZFS volumes or help with ZFS. So after the upgrade, I have to follow a modified set of these instructions (modified because the package names have changed over time) to install ZFS and its components into the system. So the sequence is: Shutdown Install via ISO Reboot to single user mode Run yum update to pull in all the updates Run the ZFS commands to install ZFS on the host Reboot again Run normally Of course, I ended up rebooting more than just those 2 times, because I forgot that I would need to install ZFS (even though I did it on 2 different hosts already ) So now the pool is fully upgraded, everybody is happy. I'm now working on creating shared storage across the nodes. It's amateur hour over here. I appreciate all the help.

    @Pilow I will take a look in deep later, but the key/delta and disk usage is set during backup, even if they are merged during LTR retention

    @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.

    I think it's "because" we fixed it upstream and then Fedora packaged the fix in their latest update

    @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?

    You will need to download the desired ISO and use it to install the base OS. Then follow the official docs or use one of the available installation scripts. AFAIK, you should be fine with Fedora.

    What operating system do you have? Does it run on the same type of real server? If not. If VM it is Windows, you must reset (sysprep) or insert the hdd drivers. Acronis is a solution for that, or Dism++ and ImDisk to insert dirvers on vhd. If VM it's Linux, you don't have the correct disk name or partition ID, the boot partition must be redone. Reinstall kernel, in chroot with live CD, to solve the problem. For an easier process, I recommend Hyper-V -> VirtualBox -> XCP-ng. With VirtualBox you will have fewer problems when restoring the boot. And VirtualBox is much more compatible with XCP-ng.

    @vbits said in Delta backup fails on SMB remote: NexentaStor SC216 Yes that was the question If you have better speed with SMB stay with it NFS should be better in theory but sometime you have to go with real world reality.
