[libvirt-users] Resizing lvm fails with fedora20

[Alex Regan]

Hi,
I'm trying to resize a 15GB LVM root partition on a fedora20 server with 
a fedora20 guest and I'm having a problem. Is this supported on fedora20?

I recall having a similar problem (maybe even exact same problem) all 
the way back in fedora16 or fedora17, but hoped/thought it would be 
fixed by now?

What are my alternatives for resizing a root partition on LVM?

Thanks,
