you will need a vgextend first something like "vgextend fedora_box1000
/dev/sdb4" that will add the disk to the vg.

the df shows these 2 are mounted:
/dev/mapper/fedora_box1000-roo
t   34G  4.5G   27G  15% /

/dev/mapper/fedora_box1000-home   17G  7.2G  8.1G  47% /home

so either /dev/fedora_box1000/home or /dev/fedora_box1000/root will
need to be extended, you can also use the names shown in the df
commands...all of the different names point to the same underlying
device.
