    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.

    @olivierlambert said in Mirror failed: @AlexanderK said in Mirror failed: "OLD_447ff17a-82bc-4d49-a177-02f9086e9a04 That's the missing bit reported by XAPI/SM, indeed. Does this mean it is a bug?

    @Meth0d thanks for sharing your experience. Fortunately I was able to just hit "Convert to HVM" after my imported PV failed to reboot after upgrade from 20.04 to 22.04 - was all set to load a livecd etc too!

    yep i know but i think it is much better to have 2 Ext SR each with 1 hdd than to have 1 SR with a raid with 2 hdd, regarding downtime in case of failure disk

    @Danp I got around this by using Clonezilla to copy the disks of the 2 VMs I was having an issue with. This is very strange. The VMs booted and ran fine on the old host, I was able to clone them with Clonezilla to the new host where they also boot and run fine. There is something preventing the native tools from migrating these specific disks though.

    @DustinB As to why you're seeing "VM not found!" I don't know if that is a XO alert or something you added into the screenshot, I've never seen that so I can't speak to it. I didn't add the text, all I did was highlight it with the red surround. Just testing the backups again using the 'Delta' method and '[NOSNAP][NOBAK] Data drive' as the name of the second drive , feeling more hopeful about this one though. I'm starting to like XO the more I use it, would be good to move to this instead of switching between 2 different XCP-ng Center EXEs. depending on the XCP-ng version on the host so I really hope I can get this to work. The scheduled hourly snapshot while the guest is running looks a great feature, although I need to learn to walk with this first before I go that far

    @HamiltonWDS Thanks for the report. As it works with wget let use it! I'll switch from curl to wget in doc. In the meantime some colleagues will investigate more.

    Thank you very much for the clear explanation @HamiltonWDS ! This will be really helpful so we find a solution for that. We might default to IPv4 for a lot higher latency, and in the future maybe having closer location mirrors. Let me discuss this internally and schedule an action for that.

    Hi! Yes, we'll develop the hub in the future, we just lack the resource internally to prioritize this against the rest, but as we a growing fast, expect more things coming in here

    I have no idea for the legacy Linux tools, they are badly coded and you can get rid of them entirely We've been using them in prod since almost a year without any issue. 1.0 will come soon but it's already very stable and safe (it's written in Rust). Our goal is to get them in all Linux distro upstream ASAP.

    Posted this as I personally found this configuration quite involved, and the permissions earlier in the thread were insufficient to make it work when using AWS KMS for bucket encryption as well as the XO provided encryption secret.

    @nick-lloyd So looked at the network ports on the host it is going to. They show disconnected due to they are in a bond lacp so the 2 network ports show as disconnected but the bond shows as connected. Also have other VMs running on the receiving host so know the bond is working.

    Check XO Lite and XO 6, it will be closer to your habits, but not XenCenter is only community supported (we don't want to support it at Vates)
