Are you running DevFS by chance?

I'm new to this whole LVM lark, and something isn't working right for

I've got a partition, /dev/hda2, which I'm trying to put LVM stuff on.

cfdisk says:

            First    Last
 # Type     Sector   Sector   Offset  Length   Filesystem Type (ID)
-- ------- -------- --------- ------ --------- ---------------------- 
 2 Primary  6249285 12466439       0  6217155  Linux LVM (8E)

Then I do:

root at gentoo daniel # pvcreate /dev/hda2
pvcreate -- physical volume "/dev/hda2" successfully created

root at gentoo daniel # pvdisplay /dev/hda2
pvdisplay -- "/dev/hda2" is a new physical volume of 2.96 GB

root at gentoo daniel # pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- inactive PV "/dev/ide/host0/bus0/target0/lun0/part2" is in no
[2.96 GB]
pvscan -- total: 1 [2.96 GB] / in use: 0 [0] / in no VG: 1 [2.96 GB]

All looking good... now here's the weird one:

root at gentoo daniel # vgcreate main /dev/hda2
vgcreate -- no valid physical volumes in command line

This is where I'm getting my baby steps from

I was using stock kernel 2.4.18 and tools 1.0.5 to start with, but just
1.1-rc2 with the same results on both.

I don't really know where to go further with this, don't know if it's
just me 
being stupid or what. Anyone got any ideas? I'll provide any info that I
to - just let me know what's needed!

Thanks awfully,
