# Command: volume status
The `volume status` command displays status information for [Container
Storage Interface (CSI)][csi] volumes.
## Usage
```plaintext
nomad volume status [options] [volume]
```
This command accepts an optional volume ID or prefix as the sole argument. If there
is an exact match based on the provided volume ID or prefix, then information about
the specific volume is queried and displayed. Otherwise, a list of matching volumes
and information will be displayed.
If the ID is omitted, the command lists out all of the existing volumes and a few
of the most useful status fields for each.
## General Options
@include 'general_options.mdx'
## Status Options
- `-type`: Display only volumes of a particular type. Currently only
the `csi` type is supported, so this option can be omitted when
querying the status of CSI volumes.
- `-plugin_id`: Display only volumes managed by a particular [CSI
plugin][csi_plugin].
- `-short`: Display short output. Used only when a single volume is
being queried. Drops verbose volume allocation data from the
output.
- `-verbose`: Show full information. Allocation create and modify
times are shown in `yyyy/mm/dd hh:mm:ss` format.
## Examples
List of all volumes:
```shell
$ nomad volume [-type csi] status
ID Name Plugin ID Schedulable Access Mode
ebs_prod_db1 database ebs-prod true single-node-writer
```
Short view of a specific volume:
```shell
$ nomad volume status [-verbose] [-plugin=ebs-prod] ebs_prod_db1
ID = ebs_prod_db1
Name = database
Type = csi
External ID = vol-23452345
Plugin ID = ebs-prod

Schedulable = true
Controllers Healthy = 1
Controllers Expected = 1
Nodes Healthy = 1
Nodes Expected = 1
Access Mode = single-node-writer
Attachment Mode = file-system
Mount Options = fs_type: ext4 flags: ro
Namespace = default
```
