    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

    @probain Your role seems to neither install or pin node js itself so it does not fully follow the official steps from Xen Orchestra docs. Xen Orchestra docs state to use LTS node js - installing it is something that the the ronivay XO script does. Due to this part missing in your role it can not be executed on a freshly provisioned VM, something that is not really best practice. A role that was made for the purpose of deploying a software should also install / manage it's dependencies. Other than that, thanks for sharing your role. Every contribution towards this community is great IMO.

    I concentrated here, after upgrading my second server: Error: /lib64/libstdc++.so.6: version `CXXABI_1.3.8' not found (required by /root/xen-orchestra/node_modules/argon2/lib/binding/napi-v3/argon2.node) I've found circumstantial evidence that this depends on libraries found in newer gcc than is in the Cent OS 7 repo at this time. strings /usr/lib64/libstdc++.so.6 | grep CXXABI CXXABI_1.3 CXXABI_1.3.1 CXXABI_1.3.2 CXXABI_1.3.3 CXXABI_1.3.4 CXXABI_1.3.5 CXXABI_1.3.6 CXXABI_1.3.7 CXXABI_TM_1 so argon2.node requires something newer than centos7 can provide?! and upgrading gcc does the trick? I may have to try when I have more time. https://stackoverflow.com/questions/63374392/node-module-argon2-usr-lib-x86-64-linux-gnu-libstdc-so-6-version-cxxabi-1 Indeed here is Centos 8. $ strings /usr/lib64/libstdc++.so.6 | grep CXXABI CXXABI_1.3 CXXABI_1.3.1 CXXABI_1.3.2 CXXABI_1.3.3 CXXABI_1.3.4 CXXABI_1.3.5 CXXABI_1.3.6 CXXABI_1.3.7 CXXABI_1.3.8 CXXABI_1.3.9 CXXABI_1.3.10 CXXABI_1.3.11 CXXABI_TM_1 CXXABI_FLOAT128 and yes, I understand that XO doesn't target CentOS, but its our 'standard' right now.

    @bsodmike Increase memory to node.js as described in the docs under memory management. Adding mem to VM is insufficient in isolation, so my post above may have been misleading (sorry!).

    @olivierlambert I think that the default behavior should be VMs stay on the SR that they are on. If you are taking a host down and moving the VMs to another host why would you move the VM storage location, that defeats one of the reasons you use shared storage.

    Yes, that's the plan: involving community for feedback. But keep in mind we don't want to make a clone of XenCenter It's a web application, so it comes with some perks but also drawbacks from a heavy client (you are running in a browser with XO, and we don't want to change all web behavior without necessity to do it). Thanks for the feedback (so feature wise I think we are at parity level, UI it's another story I agree)

    It's not a matter of believing, it's a matter of providing a way to reproduce the issue It's really hard to fix something if: we aren't aware of the issue we can't reproduce it

    Not enough space means not enough space to coalesce, and therefore XO will prevent to continue and fill entirely your storage because of uncoalesced chains.

    @tonyp90 I did file a feature suggestion, https://github.com/vatesfr/xen-orchestra/issues/4273 , but not a bug report. I'm using the xsconsole on the xcp-ng server itself in the few cases where I need to re-attach an SR. gitterdude created this issue in vatesfr/xen-orchestra closed Reattach SR icon is non-obvious #4273

    That would be interesting. This won't rule out everything but at least we might notice something different.

    Every HA or load balancing setup is too take it seriously. Consequences might be high, so use it only if we really know what you are doing.

    You need to enable hardware assisted virtualization in your hardware (in the BIOS).
