  You have a problem on your XCP-ng, this is not related to a XO issue. It's stuck doing a snapshot, which is really a basic operation that shouldn't fail at all. Double check your SMlog on the host.

  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)

  Sure, thanks. I'm using xoa and desktop app simultaneously. I hope that the desktop app will be available for long time.

  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
