Finally, I solved the problem by doing the followings:
# lvresize --size 455.5G /dev/mapper/bubba-storage
# e2fsck -f /dev/mapper/bubba-storage
# resize2fs -p /dev/mapper/bubba-storage
# reboot

So now I get back my /home partition and can ssh into my server.

Now, I can to use parted to resize my partitions.
What is my goal?

    /dev/sda2  bubba lvm2 a--  455.42g 20.00m

As one can see, my /dev/root partition is almost full.
I want to increase /dev/root partition to be maximum available size and
decrease /home partition to only 20 GiB.

So can be the /var directory large enough to encompass the web and other
contents. 

What are your advises, what do I do to reach my goal?
