I have created an c3.large instance using amazons default image "amazon-linux-centos-64-bit (ami-673af20e)". When I set it up I created a root volume of only 8GB. So theoretically I should be able to create another 8GB + 16GB SSD volume (c3.large has 2 x 16GB SSD) that I could use for swapping or so. Unfortunately I can't figure out how to do this - so my question is: can I (and if so how) create another volume that takes advantage of the SSD Speed?
Edit: I tried to find out the phyical size of the device using df:
$ df -h Filesystem Size Used Avail Use% Mounted on /dev/xvda1 7,9G 3,0G 4,9G 38% / tmpfs 1,9G 0 1,9G 0% /dev/shm
Seems the device really only has 8GB.
$ swapon -s Filename Type Size Used Priority $ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT xvda1 202:1 0 8G 0 disk /
