Various similar issues I've spotted on Reddit re. Windows updates breaking SMB Mounts over the last 12-18 months with updates. Impossible to track down the specifics so not even going to bother.
Then found this issue too, https://xcp-ng.org/forum/topic/10545/long-delays-at-46-when-creating-or-starting-a-new-vm
Which was solved by moving from SMB Mount to NFS Mount.
That isn't going to work with my infrastructure setup as the Windows machine is on a Home Edition, and NFS is only supported on Business or Enterprise edition.
As it stands right now, and given nothing I've tried to get the SMB Mount to work again, feels like I'm at a dead end to get this fixed. Looking like I'll need to re-address the architecture for storing the ISOs and one of the backup routes (thankfully there are many types of backups in place for redundancy)
Not the end of the world, but a tad annoying which feels like it's probably a Windows update that broke this with one of the almost daily automated updates/shutdowns/restarts that kicks in. Only started happening yesterday, all previous backups via the SR were working fine until then. That's the only thing I can put this down to really.
