The rest of us are just end-users, often misinformed. As far as I know, this is lore than surfaces periodically in the lists. = It was true in Solaris (at least in the past). But unless I'm terribly wrong, this doesn't happen in FreeBSD. ZFS sees = "disks", and they can be a whole raw device or a partition/slice, even a gnop device. No difference. That's why I mentioned in freebsd-fs that we badly need an official = doctrine, carefully curated, and written in holy letters ;) Borja.
