Device mapper error ioctl cmd 9. What is this?

Newbie-be gentle.
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"
Loading video_vg-video_lg
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 partitions).
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.
Thanks,
Nathan Richardson
