[linux-lvm] Question about Physical volume

[Thomas Marmetschke]

Hi,

is it possible to extend a phyiscal volume?

I have a strange problem, i resized the /dev/sda4 partion (8e Linux LVM)
from 130GB to 220GB. so far so good.

But with pvdisplay i still get the 130Gb Partion :

 pvdisplay
  --- Physical volume ---
  PV Name               /dev/sda4
  VG Name               msa
  PV Size               130,98 GB / not usable 0
  Allocatable           yes
  PE Size (KByte)       4096
  Total PE              33530
  Free PE               6394
  Allocated PE          27136
  PV UUID               TnggaW-0rIL-JaRp-JiwR-ZRlP-JJ83-LOjHfg

Can i do something like a Rescan? that the Information will be updated.
The big problem is that on this server a productive data so i can´t
remove any partions.

thx!
