    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.

    @jivanpal Right; I simply meant you could start using these to track from this point onward. Also other options, like Cacti, MRTG, etc.

    @olivierlambert said in Managing different locations from one XO?: The code is open source but you need to install it and configure it yourself (if you are using XO from Github) OK, that makes sense.

    @Andrew it seems that the merge fails but the watcher still report progress ( which doesn't move) Can you see if there is an error before ?

    You can't add a host into another pool until it's "blank". It's hard to "merge" two pools together. So first, migrate VMs to the destination, clean the host and THEN add it to the pool.

    No need to update XCP-ng, we don't want to introduce a dedicated agent. It will rely on another mechanism. We'll publish about it before the end of this summer

    XO 5.72 Storage Maintenance

    @geoffbland Hi, thanks for the reply... That's what I wound up doing, installing XO from source on a Raspberry PI that I had. I used it to restore my XO image from backup, once I did that I had to restore all of my guests (12 of them total). I could never figure out how to get my SR out of maintenance mode, so I wound up creating a new SR and restored each backup to the new SR. All back to normal after restoring the backup. Thank god XO backup works so well! I learned the hard way that I need to move my XO disks to local storage before I enter maintenance mode for my iSCSI SR... Oh well, lesson learned!

    Hi @olivierlambert we have just come across the same issue again today after the latest update. Please see below the log file for the delta backup schedule that performed full backups instead. I can't seem to find anything in the logs to help. 2022-07-12T16_00_00.013Z-backupNG.txt

    @pdonias said in Netbox Plugin Enhancements: Why do you have those interfaces? Could you explain your use case and why they're not visible in XO? Sorry, you're right, hosts are not synced for a simple reason: there is no such thing as host types in Netbox (or did we miss something?). So we only group VMs by pools (clusters) and that's it. Those interfaces are for example wireguard interfaces or any other virtual interfaces. Obv they are not in xo because they are virtual, but in netbox they are needed because I deploy all my wireguard stuff with them. The host thing already was answered, there are devices which you then can link to Pools. KR Peter

    XVA might be broken on Delta Backup

    @julien-f It is likely a broken xva. I did interrupt those as they were exporting, however I was a bit confused as to why it was checked by a different backup task. In other words this screen clip is from a delta backup, not a xva export. I was more expecting it to show up on the XVA export backup task.
