qos_policy

The QoS policy for the file. Both traditional and adaptive QoS policies are supported. If both qos_policy.uuid and qos_policy.name properties are specified in the same request, they must refer to the same QoS policy. To remove the file from a QoS policy, set the property qos_policy.name in a PATCH request to an empty string "" or "none".

Note Files which are in use as a LUN cannot be assigned to a QoS policy, instead use PATCH on /storage/luns to assign a QoS policy for such files.

Note that a QoS policy can be set on a file, or a file's volume, but not on both.

Name Type Description

_links

_links

name

string

The name of the QoS policy. To remove the file from a QoS policy, set this property to an empty string "" or set it to "none" in a PATCH request.

uuid

string

The unique identifier of the QoS policy. Valid in PATCH.

volume

Name Type Description

_links

_links

name

string

The name of the volume.

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.

  • example: 028baa66-41bd-11e9-81d5-00a0986138f7

file_info

Information about a single file.

Name Type Description

_links

_links

accessed_time

string

Last access time of the file in date-time format.

bytes_used

integer

The actual number of bytes used on disk by this file. If byte_offset and length parameters are specified, this will return the bytes used by the file within the given range.

changed_time

string

Last time data or attributes changed on the file in date-time format.

creation_time

string

Creation time of the file in date-time format.

group_id

integer

The integer ID of the group of the file owner.

hard_links_count

integer

The number of hard links to the file.

inode_generation

integer

Inode generation number.

inode_number

integer

The file inode number.

is_empty

boolean

Specifies whether or not a directory is empty. A directory is considered empty if it only contains entries for "." and "..". This element is present if the file is a directory. In some special error cases, such as when the volume goes offline or when the directory is moved while retrieving this info, this field might not get set.

is_junction

boolean

Returns "true" if the directory is a junction.

is_snapshot

boolean

Returns "true" if the directory is a Snapshot copy.

is_vm_aligned

boolean

Returns true if the file is vm-aligned. A vm-aligned file is a file that is initially padded with zero-filled data so that its actual data starts at an offset other than zero. The amount by which the start offset is adjusted depends on the vm-align setting of the hosting volume.

modified_time

string

Last data modification time of the file in date-time format.

name

string

Name of the file.

owner_id

integer

The integer ID of the file owner.

path

string

Path of the file.

qos_policy

qos_policy

The QoS policy for the file. Both traditional and adaptive QoS policies are supported. If both qos_policy.uuid and qos_policy.name properties are specified in the same request, they must refer to the same QoS policy. To remove the file from a QoS policy, set the property qos_policy.name in a PATCH request to an empty string "" or "none".

Note Files which are in use as a LUN cannot be assigned to a QoS policy, instead use PATCH on /storage/luns to assign a QoS policy for such files.

Note that a QoS policy can be set on a file, or a file's volume, but not on both.

size

integer

The size of the file, in bytes.

target

string

The relative or absolute path contained in a symlink, in the form /.

type

string

Type of the file.

unix_permissions

integer

UNIX permissions to be viewed as an octal number. It consists of 4 digits derived by adding up bits 4 (read), 2 (write), and 1 (execute). The first digit selects the set user ID(4), set group ID (2), and sticky (1) attributes. The second digit selects permissions for the owner of the file; the third selects permissions for other users in the same group; the fourth selects permissions for other users not in the group.
