I've tested with LVM2 an found, that resizing is not supported at the 
moment (newest kernel with FC3).
LVM can only grow by adding PVs to the VG. Growing PVs is not supported.
The only way is to export and reimport the VG configuration with 
vgcfgbackup and vgcfgrestore and to alter the number of physical extends 
of the grown PV manually.

Greetings,
Frank
