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?

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?
