Fedora Cookbook: Resizing a logical volume

[moi]

Root FS resizes imho usually requires the Rescue mode. Perhaps when 
growing, but shrinking is a bit tough...

You may - in rescue mode - import the Volume Group (when using LVM) and 
do the resize operations. Do not forget to do a partprobe /dev/xda, as 
the kernel will still be using the old filesystem tables when resizing 
(one of our customers did a shrink on the root partition and ran fsck, 
this made a lot of errors afterwards).
