    I spoke too soon. The issue has returned the following day which means it is most likely the nightly backups triggering the issue.

    @gcpeters4 said: @john.c This is a good idea as well. If the previous suggestion of trying to do a DNS round robin approach doesn't work, this may be my best option. Thanks for taking the time to provide your suggestion! By the way my suggestion is recommended best practice from Microsoft for their Active Directory software and/or technology. My suggestion will be more likely to work if your DNS servers and requests have issues with Round Robin configuration. Plus with my solution you can easily add more servers as domain controllers to the cluster, as required and use replication to keep them consistent and up to date.

    the last rewrite of the stream processing ( spring 2025 ) focused on stability and memory footprint, and , on a standard cpu, it tops at around 300MB/s per backup job. Your benchmarks are very interesting, and they confirm most of it. this limit was not really an issue since, in most case the xapi was limiting around 100MB/s per disk , but it will be more a more visible limit Note that master have some fixes on the memory usage (not related to backups) That's why we have started an internal workforce focused on performance, with all the teams from the kernel to the backups, including storage, network and xapi. If I can brag a little : [image: 1779106650898-afd7b59b-a4f0-4a92-88ee-2c7ba52d18bf-image.jpeg] i9 , nvme disk , backup to a nvme disk in passthrough, xoa and vm are on the same host, so it's quite far from real world data, but it shows where the limit is

    It looks like I can remove the remotes and set them up again, and configure the backup jobs to address the new share. That's okay, there are not too many.

    You need one XOA, connected to both pools. It will stream the VM content (delta) from the source to the destination. You don't need any directly link between your SR in both DCs. You DCs can be isolated with just one XOA connected to both, and it will work.

    No XCP-ng/XenServer workaround, it's a "built-in"/by design limitation (it's considered as "stalled"). So your goal would be to avoid these extremely long tasks (ie: to finish before the task is destroyed)

    You'll end up with a chain, yes (so every read will need to make "hops" on each member of the chain). Longer the chain, slower the operation. But it shouldn't be too catastrophic either (for a heavily IOPS loaded VM, you'll notice the difference, but not in other less IOPS hungry scenarios)

    No, because those logs are useful in case of problem (to find a potential bug). However, they are garbage collected automatically (the oldest ones) after a while.

    All I can tell is that's not an usual issue. Never heard of problem of this kind before… So yeah, there is something weird. Could be related to NFS permissions maybe, or something between XCP-ng and your NFS host. It's not XCP-ng code directly, because otherwise everyone else using NFS will endure the same problems. So it's more a "combo" between XCP-ng and your NFS within your infrastructure. Please read the wiki on where to check logs (especially SMlog) to spot potential hints on where's the issue.

    @S-Pam Having a VIF for management and one for storage-traffic is a good solution, we do it that way to avoid crippling management during backups.

    Any ideas for a more elegant way than to write a script? For my point of view vApps should work without HA mode but unfortunately it doesn't work on my XCP-ng server. Only console/script start of the vApp using xe appliance-start uuid= "set here the uuid of the vAppp" is working. But it is again rework for the next XCP-ng version, I think manually set vices in systemd are not persistent through an update. Will vApp supported also in future? there are some discussions about it, if really needed.

    A soft reboot will try to migrate existing VMs (ie running on this host) to another host in the pool. Using Xen motion, so only if there is a shared storage. If it fails, then you need a force reboot, that will shutdown the VM, and then reboot the host.

    IIRC, we based the button in XO to do both modification at the same time when you set it up for a VM (in the pool if it's not enabled and in the VM). However, it's been a while I didn't check the code, I'll take a look to be sure
