I have an Amazon EC2 instance that has two EBS drives associated with it: an 8 GB drive at
/dev/sda1, and a 20 GB drive at
/dev/sdf. I didn't set this up so I'm not sure why this instance needs two drives of those sizes.
I'm trying to figure out which of these two EBS drives contains the root (
/) volume. (My goal is to disconnect that drive and attach it to another instance, where I can gain access to a key file I need at
/home/ec2-user/.ssh/authorized_keys, per this excellent answer.)
How can I tell? (What is /sda1 and /sdf?)
