[linux-lvm] lvm2 problems adding a new physical volume

[Darrel Wages Jr.]

I have a vg darrel I wish to extend to a new disk.  I installed the new
disk and ran 
pvcreate /dev/hdd

it returns 
 No physical volume label read from /dev/hdd
 Physical volume "/dev/hdd" successfully created

pvscan returns 
  PV /dev/hdb    VG darrel   lvm2 [19.08 GB / 0    free]
  PV /dev/sda    VG darrel   lvm2 [8.48 GB / 0    free]
  PV /dev/hda2   VG darrel   lvm2 [26.33 GB / 0    free]
  PV /dev/hdd                lvm2 [115.04 GB]
  Total: 4 [168.93 GB] / in use: 3 [53.89 GB] / in no VG: 1 [115.04 GB]

I try to extend vg darrel with vgextend but it failed. So I ran
pvdisplay

it returns 

  --- Physical volume ---

  --- Physical volume ---
  PV Name               /dev/hda2
  VG Name               darrel
  PV Size               26.33 GB / not usable 0
  Allocatable           yes (but full)
  PE Size (KByte)       4096
  Total PE              6740
  Free PE               0
  Allocated PE          6740
  PV UUID               1Z1XPp-SzFQ-osnY-HqU5-WGsh-JXjG-TXkDoP
    
  --- NEW Physical volume ---
  PV Name               /dev/hdd
  VG Name
  PV Size               115.04 GB
  Allocatable           NO
  PE Size (KByte)       0
  Total PE              0
  Free PE               0

  PV UUID               k14iEH-C7W2-904v-DEh1-ANlT-rhD3-H3O0oP

So I try pvchange -v -x y /dev/hdd

    Using physical volume(s) on command line
  /dev/cdrom: open failed: Read-only file system
  Allocatability not supported by orphan lvm2 format PV /dev/hdd
  0 physical volumes changed / 1 physical volume not changed

I have searched the net and found nothing about this.  I have also tried
fdisk and added a lvm partition /dev/hdd1 with the same results.  I can
however make a linux partition on the disk and it works fine.  I have
used dd and blockdev as discribed in the howto to wipe the partition
table on the disk.  I am using FC2 with all the updates and latest
kernel.  This drive is a new IBM drive 120 G. 

Thank you.
