[linux-lvm] Device mapper error ioctl cmd 9. What is this?

I'm trying to set up a very simple LVM logical volume and get the
following (verbose) output from lvcreate:
Creating logical volume video_lg
Archiving volume group "video_vg" metadata.
Creating volume group backup "/etc/lvm/backup/video_vg"
Found volume group "video_vg"
device-mapper ioctl cmd 9 failed: Invalid argument
Couldn't load device 'video_vg-video_lg'.
Failed to activate new LV.
All LVM utils also seem to scan all my drives, even if I don't have
them (for example, /dev/hda6 gets listed even though I only have 5
Anyway, this seems like a device-mapper issue rather than an LVM one,
but I can't tell for sure.
I'm running Fedora core 1 with a standard 2.6.7 kernel. I have LVM2
and version 1.00.19 of the DM userspace tools.
I have no problems creating the volume group, and even after the
lvcreate seems to fail, I have an entry for the LV/VG in /dev/mapper/.
I never get the entry in /dev that I apparently need for the lvcreate
to complete and to be able to actually mount the LV.
Sorry if this is unclear - if more info is needed, let me know. Any
help is appreciated.
