I think you meant "dmsetup mknodes". :-)

What's also useful with a dynamic /dev (like mounted on ramfs with udev)
on a read-only root filesystem (I'm doing this here in the early system
boot rc when /dev is populated even before the filesystem checking and
mounting begins):

lvm vgscan --mknodes --ignorelockingfailure
