Creating file clones

The POST operation is used to create file clones with the specified attributes in body. Set the volume.name and volume.uuid to identify the volume.

Set source_path and destination_path to identify the file path of original and copied file. In case of full file clone, the new file is created using destination_path.<br> In case of a sub file clone, set range in the format source-file-block-number:destination-file-block-number:block-count. The API returns an error for the following overlapping conditions: (a) if source and destination files are same and any of the source ranges overlap with any of the destination ranges. (b) if any of the source ranges overlap amongst themselves. (c) if any of the destination ranges overlap amongst themselves. If not provided, full file cloning is assumed.

If set to autodelete, the cloned file is deleted when the volumes are full.<br>

# The API:
curl -X POST "https://<mgmt_ip>/api/storage/file/clone" -H "accept: application/hal+json" -d '{"volume": {"name": "vol1",  "uuid": "40e0fdc5-c28f-11eb-8270-005056bbeb0b"}, "source_path": "f1", "destination_path": "f2_c1"}'

# The response:
{
"job": {
  "uuid": "0d025fd9-c4dc-11eb-adb5-005056bbeb0b",
  "_links": {
     "self": {
       "href": "/api/cluster/jobs/0d025fd9-c4dc-11eb-adb5-005056bbeb0b"
     }
  }

Parameters

Name Type In Required Description

return_timeout

integer

query

False

The number of seconds to allow the call to execute before returning. When doing a POST, PATCH, or DELETE operation on a single record, the default is 0 seconds. This means that if an asynchronous operation is started, the server immediately returns HTTP code 202 (Accepted) along with a link to the job. If a non-zero value is specified for POST, PATCH, or DELETE operations, ONTAP waits that length of time to see if the job completes so it can return something other than 202.

  • Default value: 1

  • Max value: 120

  • Min value: 0

return_records

boolean

query

False

The default is false. If set to true, the records are returned.
