GET /storage/volumes/{uuid}

Retrieves a volume. The GET API can be used to retrieve the quota state for a FlexVol or a FlexGroup volume.

Expensive properties

There is an added cost to retrieving values for these properties. They are not included by default in GET results and must be explicitly requested using the fields query parameter. See DOC Requesting specific fields to learn more.

Parameters

Name Type In Required Description

uuid

string

path

True

Unique identifier of the volume.

fields

array[string]

query

False

Specify the fields to return.

Response

Status: 200, Ok
Name Type Description

_links

_links

aggregates

array[aggregates]

Aggregate hosting the volume. Required on POST.

application

application

autosize

autosize

clone

clone

comment

string

A comment for the volume. Valid in POST or PATCH.

consistency_group

consistency_group

Consistency group the volume is part of.

constituents_per_aggregate

integer

Specifies the number of times to iterate over the aggregates listed with the "aggregates.name" or "aggregates.uuid" when creating or expanding a FlexGroup. If a volume is being created on a single aggregate, the system will create a flexible volume if the "constituents_per_aggregate" field is not specified, and a FlexGroup if it is specified. If a volume is being created on multiple aggregates, the system will always create a FlexGroup.

create_time

string

Creation time of the volume. This field is generated when the volume is created.

efficiency

efficiency

encryption

encryption

error_state

error_state

files

files

flexcache_endpoint_type

string

FlexCache endpoint type. none ‐ The volume is neither a FlexCache nor origin of any FlexCache. cache ‐ The volume is a FlexCache volume. origin ‐ The volume is origin of a FlexCache volume.

guarantee

guarantee

is_svm_root

boolean

Specifies whether the volume is a root volume of the SVM it belongs to.

language

string

Language encoding setting for volume. If no language is specified, the volume inherits its SVM language encoding setting.

metric

metric

Performance numbers, such as IOPS, latency and throughput.

movement

movement

Volume movement. All attributes are modify, that is, not writable through POST. Set PATCH state to destination_aggregate to initiate a volume move operation. Volume movement on FlexGroup constituents are not supported.

name

string

Volume name. The name of volume must start with an alphabetic character (a to z or A to Z) or an underscore (_). The name must be 197 or fewer characters in length for FlexGroups, and 203 or fewer characters in length for all other types of volumes. Volume names must be unique within an SVM. Required on POST.

nas

nas

qos

qos

QoS information

quota

quota

Quotas track the space or file usage of a user, group, or qtree in a FlexVol or a FlexGroup volume.

size

integer

Physical size of the volume, in bytes. The minimum size for a FlexVol volume is 20MB and the minimum size for a FlexGroup volume is 200MB per constituent. The recommended size for a FlexGroup volume is a minimum of 100GB per constituent. For all volumes, the default size is equal to the minimum size.

snaplock

snaplock

snapmirror

snapmirror

Specifies attributes for SnapMirror protection.

snapshot_policy

snapshot_policy

This is a reference to the Snapshot copy policy.

space

space

state

string

Volume state. A volume can only be brought online if it is offline. Taking a volume offline removes its junction path. The 'mixed' state applies to FlexGroup volumes only and cannot be specified as a target state. An 'error' state implies that the volume is not in a state to serve data.

statistics

statistics

These are raw performance numbers, such as IOPS latency and throughput. These numbers are aggregated across all nodes in the cluster and increase with the uptime of the cluster.

style

string

The style of the volume. If "style" is not specified, the volume type is determined based on the specified aggregates. Specifying a single aggregate, without "constituents_per_aggregate", creates a flexible volume. Specifying multiple aggregates, or a single aggregate with "constituents_per_aggregate", creates a FlexGroup. Specifying a volume "style" creates a volume of that type. For example, if the style is "flexvol" you must specify a single aggregate. If the style is "flexgroup", the system either uses the specified aggregates or automatically provisions aggregates if there are no specified aggregates. flexvol ‐ flexible volumes and FlexClone volumes flexgroup ‐ FlexGroups.

svm

svm

SVM containing the volume. Required on POST.

tiering

tiering

type

string

Type of the volume. rw ‐ read-write volume. dp ‐ data-protection volume. ls ‐ load-sharing dp volume. Valid in GET.

use_mirrored_aggregates

boolean

Specifies whether mirrored aggregates are selected when provisioning a FlexGroup without specifying "aggregates.name" or "aggregates.uuid". Only mirrored aggregates are used if this parameter is set to 'true' and only unmirrored aggregates are used if this parameter is set to 'false'. Aggregate level mirroring for a FlexGroup can be changed by moving all of the constituents to the required aggregates. The default value is 'true' for a MetroCluster configuration and is 'false' for a non-MetroCluster configuration.

uuid

string

Unique identifier for the volume. This corresponds to the instance-uuid that is exposed in the CLI and ONTAPI. It does not change due to a volume move.

status

Name Type Description

code

string

Encryption progress message code.

message

string

Encryption progress message.

encryption

Name Type Description

enabled

boolean

Encrypts an unencrypted volume. When set to 'true', a new key is generated and used to encrypt the given volume. The underlying SVM must be configured with the key manager.

key_id

string

The key ID used for creating encrypted volume. A new key-id is generated for creating an encrypted volume. This key-id is associated with the generated key.

rekey

boolean

Indicates whether the volume has any corrupt data blocks. If the damaged data block is accessed, an IO error, such as EIO for NFS or STATUS_FILE_CORRUPT for CIFS, is returned.

boolean

Indicates whether the file system has any inconsistencies. true ‐ File system is inconsistent. false ‐ File system in not inconsistent.

files

Name Type Description

maximum

integer

The maximum number of files (inodes) for user-visible data allowed on the volume. This value can be increased or decreased. Increasing the maximum number of files does not immediately cause additional disk space to be used to track files. Instead, as more files are created on the volume, the system dynamically increases the number of disk blocks that are used to track files. The space assigned to track files is never freed, and this value cannot be decreased below the current number of files that can be tracked within the assigned space for the volume. Valid in PATCH.

iops

iops

The rate of I/O operations observed at the storage object.

latency

latency

The round trip latency in microseconds observed at the storage object.

status

string

Errors associated with the sample. For example, if the aggregation of data over multiple nodes fails, then any partial errors might return "ok" on success or "error" on an internal uncategorized failure. Whenever a sample collection is missed but done at a later time, it is back filled to the previous 15 second timestamp and tagged with "backfilled_data". "Inconsistent_ delta_time" is encountered when the time between two collections is not the same for all nodes. Therefore, the aggregated value might be over or under inflated. "Negative_delta" is returned when an expected monotonically increasing value has decreased in value. "Inconsistent_old_data" is returned when one or more nodes do not have the latest data.

timestamp

string

The timestamp of the performance data.

Whenever a sample collection is missed but done at a later time, it is back filled to the previous 15 second timestamp and tagged with "backfilled_data". "Inconsistent_ delta_time" is encountered when the time between two collections is not the same for all nodes. Therefore, the aggregated value might be over or under inflated. "Negative_delta" is returned when an expected monotonically increasing value has decreased in value. "Inconsistent_old_data" is returned when one or more nodes do not have the latest data.
