Module `netapp_ontap.resources.file_info`

Overview

This API is used to read a file, write to a file, retrieve a list of files and directories, and retrieve or modify certain properties of files and directories. The path field is used to specify the path to the directory or file to be acted on. The path field requires using "%2E" to represent "." and "%2F" to represent "/" for the path provided.

File data

Read and write data from/to a named file. To read a file, the Accept request HTTP header must be specified as multipart/form-data, and a value for the length query property, which represents the number of bytes to be read, must be specified. The API will fail if the length of data being read/written exceeds 1 MB. This API should only be used on normal files or streams associated with files. The results for other file types, such as LUNs is undefined.
The following APIs are used to read or write data to a file:

GET /api/storage/volumes/{volume.uuid}/files/{path}?byte_offset=0&length=40 -H "Accept: multipart/form-data"
POST /api/storage/volumes/{volume.uuid}/files/{path} -H "Content-Type: multipart/form-data" –form "file=the data to be written to the new file"
PATCH /api/storage/volumes/{volume.uuid}/files/{path}?byte_offset=10 -H "Content-Type: multipart/form-data" –form "file=the new data to be written or overwritten to the existing file starting at byte_offset"

Listing directories and files

A list of files and directories and their properties can be retrieved for a specified path.
The following APIs are used to view a list of files and directories:

GET /api/storage/volumes/{volume.uuid}/files
GET /api/storage/volumes/{volume.uuid}/files/{path}
GET /api/storage/volumes/{volume.uuid}/files/{path}?fields=*

File information

The metadata and detailed information about a single directory or file can be retrieved by setting the return_metadata query property to true. The information returned includes type, creation_time, modified_time, changed_time, accessed_time, unix_permissions, ownder_id, group_id, size, hard_links_count, inode_number, is_empty, bytes_used, unique_bytes, inode_generation, is_vm_aligned, is_junction, links, and analytics (if requested).
The following API is used to view the properties of a single file or directory:

GET /api/storage/volumes/{volume.uuid}/files/{path}?return_metadata=true

File usage

Custom details about the usage of a file can be retrieved by specifying a value for the byte_offset and length query properties.
The following API is used to view the unique bytes, and bytes used, by a file based on the range defined by byte_offset and length:

GET /api/storage/volumes/{volume.uuid}/files/{path}?return_metadata=true&byte_offset={int}&length={int}

Create a directory

The following API is used to create a directory:

POST /api/storage/volumes/{volume.uuid}/files/{path} -d '{ "type" : "directory", "unix-permissions" : "644"}'

Delete an entire directory

A directory can be deleted. The behavior of this call is equivalent to rm -rf.
The following API is used to delete an entire directory:

DELETE /api/storage/volumes/{volume.uuid}/files/{path}?recurse=true

Delete a file or an empty directory

The following API is used to delete a file or an empty directory:

DELETE /api/storage/volumes/{volume.uuid}/files/{path}
DELETE /api/storage/volumes/{volume.uuid}/files/{path}?recurse=false

File system analytics

File system analytics provide a quick method for obtaining information summarizing properties of all files within any directory tree of a volume. When file system analytics are enabled on a volume, analytics.* fields may be requested, and will be populated in the response records corresponding to directories. The API does not support file system analytics for requests that are made beyond the boundary of the specified volume.uuid.
The following APIs are used to obtain analytics information for a directory:

GET /api/storage/volumes/{volume.uuid}/files/{path}?fields=analytics
GET /api/storage/volumes/{volume.uuid}/files/{path}?fields=**

QoS

QoS policies and settings enforce Service Level Objectives (SLO) on a file. A pre-created QoS policy can be used by specifying the qos.name or qos.uuid properties.
The following APIs are used to assign a QoS policy to a file:

PATCH /api/storage/volumes/{volume.uuid}/files/{path} -d '{ "qos_policy.name" : "policy" }'
PATCH /api/storage/volumes/{volume.uuid}/files/{path} -d '{ "qos_policy.uuid" : "b89bc5dd-94a3-11e8-a7a3-0050568edf84" }'

Symlinks

The following APIs are used to create a symlink and read the contents of a symlink:

POST /api/storage/volumes/{volume.uuid}/files/{path} -d '{ "target" : "directory2/file1" }'
GET /api/storage/volumes/{volume.uuid}/files/{path}?return_metadata=true&fields=target

Rename a file or a directory

The following API can be used to rename a file or a directory. Note that you need to provide the path relative to the root of the volume in the path body parameter.

PATCH /api/storage/volumes/{volume.uuid}/files/{path} -d '{ "path" : "directory1/directory2" }'
PATCH /api/storage/volumes/{volume.uuid}/files/{path} -d '{ "path" : "directory1/directory2/file1" }'

Classes

class FileInfo (*args, **kwargs)

Information about a single file.

Initialize the instance of the resource.

Any keyword arguments are set on the instance as properties. For example, if the class was named 'MyResource', then this statement would be true:

MyResource(name='foo').name == 'foo'

Args

*args: Each positional argument represents a parent key as used in the URL of the object. That is, each value will be used to fill in a segment of the URL which refers to some parent object. The order of these arguments must match the order they are specified in the URL, from left to right.
**kwargs: each entry will have its key set as an attribute name on the instance and its value will be the value of that attribute.

Ancestors

Resource

Static methods

def count_collection(*args, connection: HostConnection = None, **kwargs) -> int

Fetch a count of all objects of this type from the host.

This calls GET on the object to determine the number of records. It is more efficient than calling get_collection() because it will not construct any objects. Query parameters can be passed in as kwargs to determine a count of objects that match some filtered criteria.

Args

*args: Each entry represents a parent key which is used to build the path to the child object. If the URL definition were /api/foos/{foo.name}/bars, then to get the count of bars for a particular foo, the foo.name value should be passed.
connection: The HostConnection object to use for this API call. If unset, tries to use the connection which is set globally for the library or from the current context.
**kwargs: Any key/value pairs passed will be sent as query parameters to the host. These query parameters can affect the count. A return_records query param will be ignored.

Returns

On success, returns an integer count of the objects of this type. On failure, returns -1.

Raises

NetAppRestError: If the API call returned a status code >= 400, or if there is no connection available to use either passed in or on the library.

def delete_collection(*args, records: Iterable[_ForwardRef('FileInfo')] = None, body: Union[Resource, dict] = None, poll: bool = True, poll_interval: Union[int, NoneType] = None, poll_timeout: Union[int, NoneType] = None, connection: HostConnection = None, **kwargs) -> NetAppResponse

Deletes an existing file or directory. Query-based DELETE operations are not supported.

DOC /storage/volumes/{volume.uuid}/files/{path}

Delete all objects in a collection which match the given query.

All records on the host which match the query will be deleted.

Args

*args: Each entry represents a parent key which is used to build the path to the child object. If the URL definition were /api/foos/{foo.name}/bars, then to delete the collection of bars for a particular foo, the foo.name value should be passed.
records: Can be provided in place of a query. If so, this list of objects will be deleted from the host.
body: The body of the delete request. This could be a Resource instance or a dictionary object.
poll: If set to True, the call will not return until the asynchronous job on the host has completed. Has no effect if the host did not return a job response.
poll_interval: If the operation returns a job, this specifies how often to query the job for updates.
poll_timeout: If the operation returns a job, this specifies how long to continue monitoring the job's status for completion.
connection: The HostConnection object to use for this API call. If unset, tries to use the connection which is set globally for the library or from the current context.
**kwargs: Any key/value pairs passed will be sent as query parameters to the host. Only resources matching this query will be deleted.

Returns

A NetAppResponse object containing the details of the HTTP response.

Raises

NetAppRestError: If the API call returned a status code >= 400

def find(*args, connection: HostConnection = None, **kwargs) -> Resource

Retrieves a list of files and directories for a given directory or returns only the properties of a single given directory or file of a 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 property. See Requesting specific fields to learn more. * analytics * qos_policy.name * qos_policy.uuid

Learn more

DOC /storage/volumes/{volume.uuid}/files/{path}

Find an instance of an object on the host given a query.

The host will be queried with the provided key/value pairs to find a matching resource. If 0 are found, None will be returned. If more than 1 is found, an error will be raised or returned. If there is exactly 1 matching record, then it will be returned.

Args

*args: Each entry represents a parent key which is used to build the path to the child object. If the URL definition were /api/foos/{foo.name}/bars, then to find a bar for a particular foo, the foo.name value should be passed.
connection: The HostConnection object to use for this API call. If unset, tries to use the connection which is set globally for the library or from the current context.
**kwargs: Any key/value pairs passed will be sent as query parameters to the host.

Returns

A Resource object containing the details of the object or None if no matches were found.

Raises

NetAppRestError: If the API call returned more than 1 matching resource.

def get_collection(*args, connection: HostConnection = None, max_records: int = None, **kwargs) -> Iterable[Resource]

Retrieves a list of files and directories for a given directory or returns only the properties of a single given directory or file of a volume.

Expensive properties

Learn more

DOC /storage/volumes/{volume.uuid}/files/{path}

Fetch a list of all objects of this type from the host.

This is a lazy fetch, making API calls only as necessary when the result of this call is iterated over. For instance, if max_records is set to 5, then iterating over the collection causes an API call to be sent to the server once for every 5 records. If the client stops iterating before getting to the 6th record, then no additional API calls are made.

Args

*args: Each entry represents a parent key which is used to build the path to the child object. If the URL definition were /api/foos/{foo.name}/bars, then to get the collection of bars for a particular foo, the foo.name value should be passed.
connection: The HostConnection object to use for this API call. If unset, tries to use the connection which is set globally for the library or from the current context.
max_records: The maximum number of records to return per call
**kwargs: Any key/value pairs passed will be sent as query parameters to the host.

Returns

A list of Resource objects

Raises

NetAppRestError: If there is no connection available to use either passed in or on the library. This would be not be raised when get_collection() is called, but rather when the result is iterated.

def patch_collection(body: dict, *args, records: Iterable[_ForwardRef('FileInfo')] = None, poll: bool = True, poll_interval: Union[int, NoneType] = None, poll_timeout: Union[int, NoneType] = None, connection: HostConnection = None, **kwargs) -> NetAppResponse

Args

body: A dictionary of name/value pairs to set on all matching members of the collection. The body argument will be ignored if records is provided.
*args: Each entry represents a parent key which is used to build the path to the child object. If the URL definition were /api/foos/{foo.name}/bars, then to patch the collection of bars for a particular foo, the foo.name value should be passed.
records: Can be provided in place of a query. If so, this list of objects will be patched on the host.
poll: If set to True, the call will not return until the asynchronous job on the host has completed. Has no effect if the host did not return a job response.
poll_interval: If the operation returns a job, this specifies how often to query the job for updates.
poll_timeout: If the operation returns a job, this specifies how long to continue monitoring the job's status for completion.
connection: The HostConnection object to use for this API call. If unset, tries to use the connection which is set globally for the library or from the current context.
**kwargs: Any key/value pairs passed will be sent as query parameters to the host. Only resources matching this query will be patched.

Returns

A NetAppResponse object containing the details of the HTTP response.

Raises

NetAppRestError: If the API call returned a status code >= 400

DOC /storage/volumes/{volume.uuid}/files/{path}

Send this collection of objects to the host as a creation request.

Args

records: A list of Resource objects to send to the server to be created.
*args: Each entry represents a parent key which is used to build the path to the child object. If the URL definition were /api/foos/{foo.name}/bars, then to create a bar for a particular foo, the foo.name value should be passed.
hydrate: If set to True, after the response is received from the call, a a GET call will be made to refresh all fields of each object. When hydrate is set to True, poll must also be set to True.
poll: If set to True, the call will not return until the asynchronous job on the host has completed. Has no effect if the host did not return a job response.
poll_interval: If the operation returns a job, this specifies how often to query the job for updates.

Returns

A list of Resource objects matching the provided
type which have been created by the host and returned. This is _not_
the same list that was provided, so to continue using the object, you

should save this list. If poll is set to False, then a NetAppResponse object is returned instead.

Raises

NetAppRestError: If the API call returned a status code >= 400
