Well done. You’ve learnt to create, attach, detach and delete volumes from your project using the Nectar Dashboard. You’ve also learnt how to format your attached volume from the command line, and how to mount and umount your device.
Nectar Volumes really are the virtual equivalent of USB drives.
Additional tricks you can do with Nectar volumes are you can Resize them, take volume snapshots, transfer a volume to another project and make them a boot source for instances.
