I have a huge RAID6 array 21TB+ already partitioned in GPT. This is to be used as the storage location for my company's backup server, and I want to access it as one logical volume. Is this ... [by kroby]

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?
So, I've done something foolish. I didn't know at the time that it was foolish.
I built a RAID 6 array. And instead of just putting a simple EXT3 or EXT4 file system on it. I created a Physical Volume and put a Volume Group on the volume that the RAID 6 array made. There was no real problem with that, until the machine that I built that on died.
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?
Is it possible to create a volume group from a logical volume instead of a physical volume? If so, are there any pitfalls in doing so?
Installing OpenStack Compute on a a system that already has all of the physical volumes assigned to a singe volume group. The nova-volume service requires a separate volume group, as described in the documentation.
