EC2 disks all identified as SSD. #76
Description
On an EC2 instance, disko identifies both SSD and HDD as SSD.
Here is an example, from a c1.medium:
- xvda is an 8GiB volume type gp2
- xvdc is a swap volume
- xvdd is a instance store (ephemeral0)
- xvdf is a 1GiB volume type standard
Block device mappings are:
$ u=http://169.254.169.254/latest/meta-data/block-device-mapping/;
$ for x in $(curl --silent $u); do echo $x=$(curl --silent $u/$x); done
ami=/dev/sda1
ephemeral0=sdd
root=/dev/sda1
swap=sdc
$ ./demo/demo disk scan
