All,

I followed the instructions from
http://netzooid.com/blog/2005/11/01/shriking-a-physical-volume-on-linux/
to reduce the physical volume on my laptop. I am trying to make room for
non-lvm partitions. Everything worked fine. I resized the physical volume
rom $57G to $27G however fdisk does not see the emtpy space. see below:
[root@hyllus ~]# pvs -o +dev_size --units h
  PV         VG         Fmt  Attr PSize  PFree  DevSize
  /dev/hda2  VolGroup00 lvm2 a-   27.81G 64.00M  55.79G

---

Is there something I am missing? Fdisk, parted and any other partition
utilties don't see any empty space. There is a mismatch  between the
physical volume size and what is being reported to the system. Is there a
way to shrink the size of /dev/hda2 without having to reformat? I would
rather not have to reformat, since /, /usr, /usr/local and other partitions
resized on /dev/hda2.

Any and all feedback would be greatly appreciated.

Enils
