I don't know why.
I've seen that, too, though. For me it's always been relatively
short, <1min. I wonder if there are three kinds of scrub-like things,
not just two (resilvers and scrubs), and 'zpool status' is
``simplifying'' for us again?

For me, even plain filesystems are not all remounted. ZFS tries to
mount them in the wrong order, so it would mount /a/b/c, then try to
mount /a/b and complain ``directory not empty''. I'm not sure why it
mounts things in the right order at boot/import, but in haphazard
order after one of these auto-onlines. Then NFS exporting didn't work
either.
To fix, I have to 'zfs umount /a/b/c', but then there is a b/c
directory inside filesystem /a, so I have to 'rmdir /a/b/c' by hand
because the '... set mountpoint' koolaid creates the directories but
doesn't remove them. Then 'zfs mount -a' and 'zfs share -a'.
