    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.

    Question about XO snapshot location

    Yes indeed, in CR, you'll send a copy of the disk toward a destination SR. But still, the snapshot is made on the same storage. However, I get your point, and I think in theory, it could be doable with some heavy changes in the storage stack (to have a snapshot located "elsewhere"). However, for each read in the VHD chain, you'll have to read on multiple storage at once, which can be complicated technically speaking (especially if they are shared)

    Kubernetes Recipe - Basic setup not working

    It seems that Debian Buster has some problems with Kubernetes. While this base setup is working, one should also assure that every tool uses the legacy iptables. If not, pod's will not be able to reach the kubernetes api... And then... failure all over! So we also need: update-alternatives --set iptables /usr/sbin/iptables-legacy update-alternatives --set ip6tables /usr/sbin/ip6tables-legacy update-alternatives --set arptables /usr/sbin/arptables-legacy update-alternatives --set ebtables /usr/sbin/ebtables-legacy ```

    Hi, Audit logs aren't in the same location than the xo-server logs. To get Audit logs you can use this command xo-cli audit.getRecords which returns an array of records. xo-cli audit.getRecords This command has an option ndjson, which allows you to export logs in a ndjson format. xo-cli audit.getRecords ndjson="json:true" @=<outputPath>

    @Rocky most like a connection issue, but since you already restarted I think the logs are already gone. If it was a one-off I wouldn't worry about it (but do make sure that the backup is actually working, may be a good idea to do another full backup).

    XO debian 10 cloud ready VM template (cloud-init)

    I was able to find the reason XO is not working with cloud-init. XO attaches iso with the cloud-config data as additional disk xvdb and it does not work. But if you provide it as a cd? It will. That is why - as for now you will need to create your own iso and attach it as a cd-rom. You do that this way: Get your files ready (meta-data network-config user-data). My examples below: metadata: instance-id: local-nocloud local-hostname: myhost.example.com network-config: network: version: 1 config: - type: physical name: eth0 subnets: - type: static address: 10.0.0.5/24 gateway: 10.0.0.254 - type: nameserver address: - 8.8.8.8 - 8.8.4.4 search: - example.com - type: physical name: eth1 subnets: - type: static address: 192.168.0.5/24 user-data: #cloud-config ### RUN CMD runcmd: - /usr/bin/apt -y install mc - /usr/bin/date >> /root/testfile # set system default user system_info: default_user: name: testuser gecos: Default Cloud User # password auth - comment out if not using passwords password: testpassword ssh_pwauth: true chpasswd: { expire: false } # do some package management #package_update: true packages: - iptraf - mtr - screen - net-tools - atop Generate iso genisoimage -output myiso.iso -volid cidata -joliet -rock user-data meta-data network-config Upload iso to XO home -> storage -> iso's -> disks -> new disk Prepare VM/template Install Debian 10.6 with xo-tools install cloud-init and cloud-initramfs-growroot remove all network configuration leave just "allow-hotplug ethxxx" (network config will be added in /etc/network/interfaces/50-cloud-init. It will not overwrite yours) shutdown the machine and create the template if you want or just restart VM. DO NOT LET IT BOOT! - keep it in grub. attach your iso let it run It will do whatever you need on the machine.

    @olivierlambert said in Detached Backups: You can do that already if you like (combined rolling snap and delta backup). But what's the point? Oh, wow. You can combine backup methods in the same job (as long as they are compatible methods (i.e. Delta and CR). This is cool. I currently have separate jobs for my deltas and CRs. I'll need to make time to make the changes, but this will simply things greatly. I'll even throw in a few extra snapshots to retain. So, yea, this is pretty much what I was thinking of. I didn't realize it was there. Why would I need this? Well, when my WSUS installed the Xen drivers on all my Windows VMs, I went a day before realizing what happened. A snapshot would have been sufficient, if I had one from the day before. Instead, I restored the backup which broke the chain. @olivierlambert said in Detached Backups: edit: about your previous question, restoring without breaking the chain. That might be possible. In theory, after restore, we should take a snapshot before booting the backup and then re-link the restored VM to the backup folders. It's doable (renaming some folders correctly) but I'm not sure this will be very useful. I'll look into this when I get some time. Thanks.
