Hi Chris,

I finally got the time to check into this.

The iso is Fedora-Live-Xfce-x86_64-20-1 copied to and booted from a 
thumb drive.

I'm not sure how to reproduce the install problems elsewhere but here is 
how the problem manifests itself here:

The LVM system has this to say:

PV is 148.53GiB consumed 100% by a VG, extents are 32MiB.
pvdisplay and vgdisplay report free space 1805/56.41GiB.

The installer reports 1.71GiB available space.  Somewhere between the 
tools to which I have access and the installer 54.70GiB have gone 
unaccounted for.  I've rebooted from the thumb drive several times just 
to make sure something wasn't hanging around.

I've created and removed many LVs on this drive so my best guess is that 
somehow the installer is arriving at its idea of free space by counting 
as used space some that has been previously freed.

Any idea where to go from here?

Thanks,
Mike Wright
