Usage: nomad volume status [options] <id>
Display status information about a CSI volume. If no volume id is given, a
list of all volumes will be displayed.
When ACLs are enabled, this command requires a token with the
'csi-read-volume' and 'csi-list-volumes' capability for the volume's
namespace.
General Options:
` + generalOptionsUsage(usageOptsDefault) + `
Status Options:
-type <type>
List only volumes of type <type>.
-short
Display short output. Used only when a single volume is being
queried, and drops verbose information about allocations.
-verbose
Display full volumes information.
-json
Output the volumes in JSON format.
-t
Format and display volumes using a Go template.
