+  snapshot-id         ID of the snapshot affected by the action.
+  [terminal-status]   Expected terminal status, will wait until this status is reached. (unknown_status | creating | available | error | deleting | deleted | in_use | locked | exporting)
+  [zone=fr-par-1]     Zone to target. If none is passed will use default zone from the config (fr-par-1 | fr-par-2 | fr-par-3 | nl-ams-1 | nl-ams-2 | nl-ams-3 | pl-waw-1 | pl-waw-2 | pl-waw-3)

 ## A Block Storage volume is a logical storage drive on a network-connected storage system. It is exposed to Instances as if it were a physical disk, and can be attached and detached like a hard drive. Several Block volumes can be attached to one Instance at a time
 
 Block volumes can be snapshotted, mounted or unmounted.
