# Block volumes with `aral`

    aral volume create --name data --size 20 --region hel1   # size in GB, MINIMUM 10
    aral volume list
    aral volume attach --server-id <server-id> <volume-id>
    aral volume detach <volume-id>
    aral volume delete <volume-id>

Attach is asynchronous: the device appears in the guest a few seconds later
(check `lsblk` over SSH). Detach before delete. A volume survives server
deletion — it is its own resource with its own billing.
