Then the root ZFS folders of all local drives that I think have snapshots enabled are unmounted. So I have to unmount them all hard and remount them. Also the root ZFS folders from replicated ZFS folders are unmounted. This is why I assume that there is a
link between the problems and auto-sync or snapshotting.<o:p></o:p></span></p>
