Create LVM volume from multiple disks

Recently I had to crate an Amazon EC2 Instance with a storage capacity of 5Tb, unfortunately, Amazon only allows us to create 1Tb volumes so I had to create 5 volumes, attach them to the instance and create a 5Tb LVM device.

My instance was running Ubuntu and I hat to install the lvm2 package:

apt-get install lvm2 

The volumes attached to my instance where named from /dev/xvdg to /dev/xvdk

to find the names you can use the command:

fdisk -l

First we have to prepare our volumes for LVM with:

pvcreate /dev/xvdg /dev/xvdh /dev/xvdi /dev/xvdj /dev/xvdk

You can run the following command to check the result:

pvdisplay

The next step is to create a volume group, I used the command:

vgcreate storage /dev/xvdg /dev/xvdh /dev/xvdi /dev/xvdj /dev/xvdk 

And used the command:

vgdisplay

to check the result, you can also use:

vgscan 

Now we need to create the logical volume, in this case I wanted to use the entire available space so, I used the command:

lvcreate -n data -l 100%free storage

And

lvdisplay 

to check the new volume if every thing goes well it should be on /dev/storage/data 

you can also use the command 

lvscan

Now you just have to format the new device, you can use:

mkft -t ext4 /dev/storage/data

When ready you can mount it with:

mout /dev/storage/data /mnt
