Which in practice means that if you need it, you know it. Me, I have a startup time under one minute for my small cell of some 400 volumes over 1,5TiB data. This using a small and old Supermicro machine with ZFS and FreeBSD. My recollection was that the dafs was to be generally preferred in all cases. But I haven't interacted closely with those bits, so I'm just relaying hearsay; it would be good if someone closer to that work could chime in. -Ben
