Create a Volume

There are four ways of creating volume. Using option --size creates a default, empty volume. Where as --snapshot, --source, and --image copies existing volumes.

--description <volume-description> can be added for additional descriptions.

openstack volume create --size <size-in-GB> <volume-name>
openstack volume create --snapshot <snapshot-name-or-id> <volume-name>
openstack volume create --source <volume-name-or-id> <volume-name>
openstack volume create --image <image-name-or-id> <volume-name>

Delete a Volume

openstack volume delete <volume-name-or-id>

Attach a Volume to an Instance

Two useful options are --enable-delete-on-termination and --disable-delete-on-termination.
--enable-delete-on-termination deletes the volume once instance is deleted.
--disable-delete-on-termination keeps the volume in the project once instance is deleted.

openstack server add volume <instance-name-or-id> <volume-name-or-id>

Detach a Volume from an Instance

openstack server remove volume <instance-name-or-id> <volume-name-or-id>

Extend a Volume

openstack volume set --size <size-in-GB> <volume-name-or-id>

List Snapshots

openstack volume snapshot list
