Add EBS to Ubuntu EC2 Instance

add_ebs_to_ubuntu_ec2

You need to format the EBS volume (block device) with a file system between step 1 and step 2. So the entire process with your sample mount point is:

Create EBS volume.

Attach EBS volume to /dev/sdf (EC2's external name for this particular device number).

Format file system /dev/xvdf (Ubuntu's internal name for this particular device number):

sudo mkfs.ext4 /dev/xvdf
Mount file system (with update to /etc/fstab so it stays mounted on reboot):

sudo mkdir -m 000 /vol
echo "/dev/xvdf /vol auto noatime 0 0" | sudo tee -a /etc/fstab
sudo mount /vol

move your data to the new volume, then create a symbolic link from the old path to the data in the new volume.

# -m 000
#Turning off all bits in the mode is a simple indicator that nobody should be allowed to do anything in this directory until a #new file system is mounted here. It's a message that this directory has been created as a mount point. It is not required for #functionality, but sometimes avoids the mistakes of creating files when the desired volume is not mounted
