Linux initially comes with hard drive partitioned and Logical volume made. What is that used for? On /dev/mapper, I see logical volume named after my computer and it has /home and such.... [by shuhei]

I've successfully extended a logical volume on Ubuntu server 14.04 from the initial setup volume (1 TB hard drive) to include the other SSD in the server (120 GB). KVPM says that the logical volume includes both physical volumes, but that the new SSD physical volume is inactive.
I'm thinking to get a new external hard disk and using vgextend to add it to a logical volume I have set up that needs to be pretty big. Can this work, and if yes, what would happen if the externel drive became unplugged for instance... would that bork the logical volume and perhaps cause irretrevable data loss?
On my 240 GB SSD i had at first two partitions, one containing the Logical Volume with Linux Mint and the other had contained a NTFS partition to share with Windows.
Now i removed the NTFS partition and want to extend my logical volume group to use the released disk space.
How do i extend the volume group, my logical volume containing /home and the filesystem (ext4) on /home?
I added a Volume group in Proxmox VE as Storage for KVM VMs. A new Logical Volume will be created for each VM, but in Proxmox VE under The Defined Storage which shows list of created Logical Volumes I see my Logical Volume marked as RAW format. Is this a RAW image or a Logical Volume (LVM)?
I have an LVM2 logical volume that is formatted with ext4 and mounted to a directory on /opt. On that volume is a qcow2 KVM image for a Windows 7 guest. Can I snapshot the LVM logical volume for a complete backup/clone of the VM?
