what do you get from

     # vgs

?

if there's VFree, you can lvextend the backing LV behind /home, then 
grow the file system to use that additional space.

# lvextend -L +8G vg_ysg/lv_home
# resize2fs /home

if there's no VFree, and you want everything in /   you could reboot to 
single user mode, and do something like...

# cd /
# mkdir /home2
# mv /home/* /home2       # this will take awhile
# umount /home
# rmdir /home
# mv /home2 /home

and vi /etc/fstab and remove the mount for /home

now, you can lvremove vg_ysg/lv_home   to free up the space it used 
(will probably need a --force), then lvextend the vg_ysg/lv_root volume, 
and grow /that/ file system to suit.

note.  I typed all that off the top of my head.  TRUST NOTHING, VERIFY 
EVERYTHING, UNDERSTAND THE MEANING OF EVERY COMMAND YOU ARE DOING!!!  
Caveat Emptor.
