GET /storage/volumes/{uuid}

Introduced In: 9.6

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 Requesting specific fields to learn more.

Name Type Description

_links

_links

access_time_enabled

boolean

Indicates whether or not access time updates are enabled on the volume.

activity_tracking

activity_tracking

aggregates

array[aggregates]

Aggregate hosting the volume. Required on POST.

analytics

analytics

anti_ransomware

anti_ransomware

Anti-ransomware related information of the volume.

anti_ransomware_state

string

The Anti-ransomware state of the volume. If no "anti_ransomware_state" property is specified, the volume inherits the value from its parent SVM's "anti_ransomware_default_volume_state" property. If this value is "disabled", Anti-ransomware is disabled on the volume. If this value is "enabled", Anti-ransomware is enabled on the volume and alerts are raised if any suspect is detected for those volumes. If this value is "dry_run", Anti-ransomware is enabled in the dry-run or learning mode on the volume. The "dry_run" state is same as the "enabled" state except that the analytics data is used here for learning. No alerts are raised for any detections or violations. If this value is "paused", Anti-ransomware is paused on the volume. Additionally, three more states are available, which are only valid for GET. If this value is "disable_in_progress", Anti-ransomware monitoring is being disabled and a cleanup operation is in effect. If this value is "enable_paused", Anti-ransomware is paused on the volume from its earlier enabled state. If this value is "dry_run_paused", Anti-ransomware monitoring is paused on the volume from its earlier dry_run state. For POST, the valid Anti-ransomware states are only "disabled", "enabled" and "dry_run", whereas for PATCH, "paused" is also valid along with the three valid states for POST.

application

application

asynchronous_directory_delete

asynchronous_directory_delete

Configuration for asynchronous directory delete from the client. This is only supported on Flexible volumes and FlexGroup volumes.

autosize

autosize

clone

clone

cloud_retrieval_policy

string

This parameter specifies the cloud retrieval policy for the volume. This policy determines which tiered out blocks to retrieve from the capacity tier to the performance tier. The available cloud retrieval policies are "default" policy retrieves tiered data based on the underlying tiering policy. If the tiering policy is 'auto', tiered data is retrieved only for random client driven data reads. If the tiering policy is 'none' or 'snapshot_only', tiered data is retrieved for random and sequential client driven data reads. If the tiering policy is 'all', tiered data is not retrieved. "on_read" policy retrieves tiered data for all client driven data reads. "never" policy never retrieves tiered data. "promote" policy retrieves all eligible tiered data automatically during the next scheduled scan. It is only supported when the tiering policy is 'none' or 'snapshot_only'. If the tiering policy is 'snapshot_only', the only data brought back is the data in the AFS. Data that is only in a snapshot copy stays in the cloud and if tiering policy is 'none' then all data is retrieved.

comment

string

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

consistency_group

consistency_group

Consistency group the volume is part of.

constituents

array[constituents]

FlexGroup Constituents. FlexGroup Constituents can be retrieved more efficiently by specifying "is_constituent=true" or "is_constituent=true&flexgroup.uuid=" as query parameters.

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 volume. If a volume is being created on a single aggregate, the system creates a flexible volume if the "constituents_per_aggregate" field is not specified, or a FlexGroup volume if it is specified. If a volume is being created on multiple aggregates, the system always creates a FlexGroup volume. The root constituent of a FlexGroup volume is always placed on the first aggregate in the list.

convert_unicode

boolean

Specifies whether directory Unicode format conversion is enabled when directories are accessed by NFS clients.

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

flash_pool

flash_pool

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.

flexgroup

flexgroup

granular_data

boolean

State of granular data on the volume. This setting is true by default when creating a new FlexGroup volume, but can be specified as false at the time of creation via a POST request. On FlexVol volumes, the setting is always false, as only FlexGroup volumes and FlexGroup constituents support this feature. Once enabled, this setting can only be disabled by restoring a Snapshot copy. Earlier versions of ONTAP (pre 9.11) are not compatible with this feature. Therefore, reverting to an earlier version of ONTAP is not possible unless this volume is deleted or restored to a Snapshot copy that was taken before the setting was enabled.

  • Introduced in: 9.11

guarantee

guarantee

idcs_scanner

idcs_scanner

Inactive data compression scan looks and picks up blocks that have not been read for a certain amount of time(threshold_inactive_days). These blocks are then compressed in 32K chunks. All attributes are valid for GET only, expect for 'op_state' that is valid for PATCH and GET, and is used to start/stop the scanner.

is_object_store

boolean

Specifies whether the volume is provisioned for an object store server.

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.

max_dir_size

integer

Maximum directory size. This value sets maximum size, in bytes, to which a directory can grow. The default maximum directory size for FlexVol volumes is model-dependent, and optimized for the size of system memory. Before increasing the maximum directory size, involve technical support.

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.

msid

integer

The volume's Mirror Set ID.

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

queue_for_encryption

boolean

Specifies whether the volume is queued for encryption.

quota

quota

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

rebalancing

rebalancing

Configurations and settings involving non-disruptive volume capacity rebalancing for a FlexGroup volume.

scheduled_snapshot_naming_scheme

string

Naming Scheme for automatic Snapshot copies:

  • create_time - Automatic Snapshot copies are saved as per the start of their current date and time.

  • ordinal - Latest automatic snapshot copy is saved as .0 and subsequent copies will follow the create_time naming convention.

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_count

integer

Number of Snapshot copies in the volume.

snapshot_policy

snapshot_policy

This is a reference to the Snapshot copy policy.

space

space

state

string

Volume state. Client access is supported only when volume is online and junctioned. Taking volume to offline or restricted state removes its junction path and blocks client access. When volume is in restricted state some operations like parity reconstruction and iron on commit are allowed. 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.

status

array[string]

Describes the current status of a volume.

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. The style "flexgroup_constiutent" is not supported when creating a volume. flexvol ‐ flexible volumes and FlexClone volumes flexgroup ‐ FlexGroup volumes flexgroup_constituent ‐ FlexGroup constituents.

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.

tiering

Name Type Description

min_cooling_days

integer

This parameter specifies the minimum number of days that user data blocks of the volume must be cooled before they can be considered cold and tiered out to the cloud tier. Note that this parameter is only used for tiering purposes and does not affect the reporting of inactive data. The value specified should be greater than the frequency with which applications in the volume shift between different sets of data. This parameter cannot be set when volume tiering policy is either "none" or "all". The default value of this parameter depends on the volume's tiering policy. See the tiering policy section of this documentation for corresponding default values. If the tiering policy on the volume gets changed, then this parameter will be reset to the default value corresponding to the new tiering policy.

object_tags

array[string]

This parameter specifies tags of a volume for objects stored on a FabricPool-enabled aggregate. Each tag is a key,value pair and should be in the format "key=value".

policy

string

Policy that determines whether the user data blocks of a volume in a FabricPool will be tiered to the cloud store when they become cold. FabricPool combines flash (performance tier) with a cloud store into a single aggregate. Temperature of a volume block increases if it is accessed frequently and decreases when it is not. Valid in POST or PATCH. all ‐ This policy allows tiering of both Snapshot copies and active file system user data to the cloud store as soon as possible by ignoring the temperature on the volume blocks. auto ‐ This policy allows tiering of both snapshot and active file system user data to the cloud store none ‐ Volume blocks will not be tiered to the cloud store. snapshot_only ‐ This policy allows tiering of only the volume Snapshot copies not associated with the active file system. The default tiering policy is "snapshot-only" for a FlexVol and "none" for a FlexGroup. The default minimum cooling period for the "snapshot-only" tiering policy is 2 days and for the "auto" tiering policy is 31 days.

supported

boolean

This parameter specifies whether or not FabricPools are selected when provisioning a FlexGroup without specifying "aggregates.name" or "aggregates.uuid". Only FabricPool aggregates are used if this parameter is set to true and only non FabricPool aggregates are used if this parameter is set to false. Tiering support for a FlexGroup can be changed by moving all of the constituents to the required aggregates. Note that in order to tier data, not only does the volume need to support tiering by using FabricPools, the tiering "policy" must not be 'none'. A volume that uses FabricPools but has a tiering "policy" of 'none' supports tiering, but will not tier any data.
