All too often the Parallels VM (Windows 10 in this case) is being shut down uncleanly when macOS (Catalina 10.15.x) shuts down or is restartet. I don't know why this happens? Normally I would assume that the VM is also being shuw down cleanly as the host OS does. Anyway, when after this situation the VM is started again, the fsck that is due brings the whole system performance down to its knees that normal working is impossible. It hogs my machine for hours until the fsck is done. Why can't the fsck be run at very low priority?
