    I got the XO VM back up by rebooting my Pool Master XCP Host which forced the VM to shutdown. Not thrilled this happened. Migrating the XO VM in XO needs work. So, for the process of rebooting XCP Hosts after applying patches, either via RUP or manually, use the following process (Vates Team correct as needed): 1. Apply patches 2. Migrate all VMs off the Master XCP Host. If the XO VM is on this Host, do not migrate 3. Log out of XO 4. SSH into the XO VM and shut it down 5. Log into the Master XCP Host XO-Lite 6. SSH into the Master XCP Host and reboot it 7. Once the Master XCP Host is back online, power the XO VM back on via XO-Lite 8. Migrate VMs back to Master XCP Host as needed 9. If Master role changed to another Host, from the Pool > Advanced tab, change the Master back to desired XCP Host 10. Reboot other XCP Hosts in Pool to finalize applying patches. Before doing so, make sure to migrate VMs off

    hello running xcp-ng version 8.2.1 build date 2025-05-07 restart of node has been done netdata-ui version 1.19 release 6.xcpng8.2 from xcp-ng-updates repo netdata version1.44.3 release 6.xcpng8.2 from xcp-ng-updates repo confirmed following also installed xen-dom0-libs-devel yajl-devel xen-devel i have removed and reinstalled netdata-ui as well this was working fine before but sometime in the last few months , maybe when netdata updated to the versions above and the interface all changed, VM's are no longer visible in netdata [image: 1747811341191-c0b11d3e-0a0f-41dc-b122-4f1e769a92fe-image.png] use to be a giant list of VMs here, this is happening on all my xcp-ng servers, not just the one. they are all at the above mentioned xcp-ng version and netdata version. anyone else experiencing this? have any suggestions on whats going on, why the VM's are not showing up in netdata anymore on any of my hosts?

    Backup a VM with all its snapshots?

    @Zevgeny For a few snapshots it's fine - the issue comes when you have large numbers. Most of my first-hand experience with this specific issue comes from Hyper-V but the logic applies here. This is from VMware but the concept is the same and has some good reading on snapshots in general. Running a virtual machine on a snapshot for extended periods of time can cause instability and data loss. https://kb.vmware.com/s/article/1015180 The underlying issue stems from the nature of snapshots. With none you have a single VHD containing all of the data for the VM, once you take a snapshot a new delta VHD is created with all new data written going forward from the time of the snapshot. So, in order to have a complete VM you have the original VHD + the delta VHD. This is fine in smaller numbers, but once you start having 10, 15, 20+ snapshots, every one of those represents an additional VHD in the chain. This results in performance degradation because you're reading from multiple potential files as only new data is written to the deltas. This is actually from XO's blog: https://xen-orchestra.com/blog/xenserver-coalesce-detection-in-xen-orchestra/

    Happy to do baby steps If / when you guys add some kind of "register" option to get a count on things I'd add my instance(s), as long as it doesn't break the existing install / upgrade scripts at least! Generally I have no issues with just clicking it away since I'm the only one that sees it. If it were a viable option sometime in the future, those would be my ideal "features". I've really enjoyed using XO coming from ESXi / vCenter at work and formerly running my home lab. Your vision of support is similar to Nutanix's which is partially why we went their route for our server overhaul and I think it's excellent. I'm hoping by the time we're due for a refresh the hyper-converged offering is fleshed out and production ready. Though I would miss my integrated firmware upgrades.

    @olivierlambert Yes this is really great. I have a windows box where I experiment with bluetooth a bit and having backup on this machine at least once a week or so feels very good I think I think it also makes sense that a machine that needs to be taken down in order to make backup also probably will need another backup schedule.

    @ronivay very good point thank you! I guess hourly is excessive when snapshots are available. Will just schedule hourly snapshots instead as the main point is to be able to revert in the event of a breaking change.

    @julien-f Restore showed that there were backups even when it said it failed.... I did not test one, sorry. I deleted the snapshots and old backup data which forced a full backup to S3 and XO was happy. A delta backup after that was also successful.

    @MilitaryNerd Have you restarted the host since removing this bond? It's reporting that bond0 is still attached to an OVS bridge, so it may need a reboot. You can also ensure the bond is really gone by running xe bond-list, it should return nothing. You could also still have the bond PIF existing or other networks using the old bond, check that you don't have any PIFs with device ( RO): bond0 listed when running xe pif-list

    @andrewreid Not that this helps with your error, but my nightly S3 delta backups to Wasabi have been working just fine. I'm using XO source and keep mostly up to date with master. S3 and NFS are different backup formats so NFS working does not mean S3 will work. Sometimes Wasabi causes failures but not recently and not that last more than a few VMs in one night. The next backup run (manual restart or next nightly) seems to work correctly. I force a full backup every 3 months just to make sure I have a good checkpoint in case undetected corruption creeps into the delta data. Plus I have replication and other backups. I did have a problem once (not exactly yours) with a VM and just deleted the S3 backup data which forced a full backup again. Sucks because you don't have the weeks of deltas anymore. Error #3 (date-time) is strange. May be a backblaze issue. You could create a new S3 remote to backblaze (new bucket or directory) and test one failing VM backup to the new remote and see if it works (and works again for delta). You could set the retention low to test merge too. I have a setup like this with a local MinIO server for S3 testing and local backups.

    @olivierlambert I want to move them on NFS in order to be able to backup later from NFS to S3 in more granular way Generally, we are talking about XO - NFS. S3 would be out of XO.

    Just if somebody else is searching for the same thing, although it is not directly related to XOA: If you want to get these alerts by mail and you are not using XCP-ng-Center, you can activate them with: xe pool-param-set uuid=pool-uuid other-config:mail-destination=mail@example.com xe pool-param-set uuid=pool-uuid other-config:ssmtp-mailhub=mailserverip:port KPS

    @geoffbland No problem. It's the first time I see this error with tapdisk (and it's it's even more surprising to have it on this type of SR...). It had all been working fine and I had not changed anything on the share - it just stopped working In this case, maybe there was a problem with the XAPI, a lock on the device or something else. Not easy to find the cause without remote access. Don't hesitate to ping us if this problem comes back.

    Migrating large disk - any risks?

    It's more a less that. In short, the new disk is created on both sides, and blocks mirrored on both sides. First, the read only "parent" VDI with frozen blocks is copied, when it's done, the VM is briefly paused, the memory migrated to the destination and then unpaused on destination. Consequently, only the blocks written during 11 hours will use space for new blocks on the source SR (and destination, since it's mirrored).

    @sbz71 The stable channel should not have the issue, not sure when we'll release a fix for latest. If you have an XO subscription, you can open a support ticket and a support tunnel and we'll be able to patch your install My bad, I misunderstood the question
