nvme-amz
A Rust library to probe NVMe devices in Amazon EC2.
It provides functionality similar to that of the ebsnvme-id
command but adds information about instance store devices, not only EBS.
To use this library, you must define one of the features ioctl-nix
or ioctl-rustix
. Either nix or rustix will be pulled in as dependencies, respectively. The chosen library is used to make ioctl system calls.
The library implements TryFrom<File>
for Nvme
, so this is how to interact with it. For example:
use nvme_amz::Nvme;
fn main() {
let file = File::open("/dev/nvme0").expect("unable to open device");
let nvme: Nvme = file.try_into().expect("unable to probe device");
println!("{:?}", nvme);
}
Output for an EBS volume:
Nvme { names: Names { device_name: Some("sda"), virtual_name: None }, model: AmazonElasticBlockStore, vendor_id: VendorId(7439) }
Output for an instance store volume:
Nvme { names: Names { device_name: Some("sdb"), virtual_name: Some("ephemeral0") }, model: AmazonInstanceStore, vendor_id: VendorId(7439) }
