    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

    @Darkbeldin I wasn't sure about turning on two-factor. I went through that process and generated the "app password" and it seems to be working. Thanks for the info!

    FYI, we modified the deploy script to be able to automatically modify XOA's VIF to run on the management network. So even in case of using only bonded networks like @Low351, this will now work.

    @davidg said in Dashboard Health gives 'an error has occurred': 5.58.1 That's ancient, so not a valid comparison. It's likely that a recent commit has broken something that they will eventually identify / fix.

    @olivierlambert We are using rrd2csv to get host cpu stats into SQL to provide nice Grafana page sorted by pool. It would be nice to dial even further down to the vm's that are running high cpu or have memory burden.

    That's correct. There's no more updates, that's why you MUST upgrade to 8.2 (see https://xcp-ng.org/docs/releases.html#all-releases )

    @wade_solarch Short answer: try to avoid that. Back in the old XenServer days, you had to manually change the cpu feature flags so it would work at all. https://xcp-ng.org/docs/requirements.html#pool-requirements This confirms that you can't mix Intel & AMD in a pool https://xcp-ng.org/docs/requirements.html#pool-requirements This explains Heterogeneous pools a little

    VDI to coalesce number should decrease over time yes. If it's not, you might have a coalesce issue in your storage, check the /var/log/SMlog in the relevant host (master for shared storage, the host attached to its local storage otherwise). Rescan will scan for the LV/VHD files. But coalesce is automatically checked/started every 5 minutes. Coalesce can take time (depending on SR read/write and quantity to "merge"). Next releases will have a visible task for pending coalesce (next major XCP-ng release). Until then, you can do a ps axf | grep coalesce to see if there's something happening.

    Something is maybe interfering with websockets. Have you tried in private mode in case there's a problem with your cookies? If you have pro support, that might be the right time to open a support ticket so we can assist you remotely

    Are you sure your XOA is up to date? The question mark icon might indicate your XOA isn't registered. In that case, it's not up to date
