Yup. Boot into rescue mode, the make sure the sysimage root is not
mounted and then resize2fs && lvm resize. Since you're presumably
talking about FC2test, not FC1, you may have to lvm vgcfgbackup && lvm
vgcfgrestore to get the free PE count in the PV fixed (bug 112089,
fixed in LVM2 CVS but not yet in rawhide).

Yup, that's the beauty of LVM.

Last I tried, it didn't work. No harm done, the syscall just failed.
