Can't Reboot VMs (or Force Reboot) or Start VMs - Getting Blocked by SR.Scan - But Running VMs are fine?

[MichaelCropper]

Same behaviour across XO, XOA + XCP-ng Centre.

Not had this before, I'm struggling to restart VMs. I first noticed that some of the backup tasks yesterday were running way longer than they normally do, and then still running into today which is when I started investigating the issue.

The biggest clue at the moment is when running the command;

xe task-list

uuid ( RO)                : 92b59f22-15ae-2551-8839-f0f938a07af7
          name-label ( RO): SR.scan
    name-description ( RO):
              status ( RO): pending
            progress ( RO): 0.000


uuid ( RO)                : 880f0f4a-8e84-0954-2521-81831d559dd3
          name-label ( RO): Async.VM.hard_shutdown
    name-description ( RO):
              status ( RO): pending
            progress ( RO): 0.273

Tried;

xe-toolstack-restart

Made no difference.

Just seeing if there is any more debugging I can do to try and get this working without doing a full host power off/on.

It's all strange though as the running VMs are all working fine.

The Storage Repository it appears to be getting stuck on is the one storing the ISOs for the VMs. Yet nothing has changed at all.

The Host can ping the Storage Repository fine too.

Any ideas what to test to get this back working without a full Host reboot?

I've been round the loop many times of killing the stuck tasks and then trying to Start/Stop VMs and same issue each time, just goes back to the same hung state.

Storage Repository is on a Windows machine, so the only thing that is jumping to mind is some janky automatic Windows update that has kicked in and broken something. But it's strange the running VMs are still working with their ISOs sitting in that same Storage Repository (I'm not 100% clear off the top of my head if running VMs still require access to the ISO Storage Repository to be running post-boot)
