POST /storage/qtrees

Introduced In: 9.6

Creates a qtree in a FlexVol volume or a FlexGroup volume.

After a qtree is created, the new qtree is assigned an identifier. This identifier is obtained using a qtree GET request. This identifier is used in the API path for the qtree PATCH and DELETE operations.

Required properties

  • svm.uuid or svm.name - Existing SVM in which to create the qtree.

  • volume.uuid or volume.name - Existing volume in which to create the qtree.

  • name - Name for the qtree.

If not specified in POST, the values are inherited from the volume.

  • security_style - Security style for the qtree.

  • unix_permissions - UNIX permissions for the qtree.

  • export_policy.name or export_policy.id - Export policy of the SVM for the qtree.

  • qtree create

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.

  • Default value:

When "min_throughput_iops", "min_throughput_mbps", "max_throughput_iops" or "max_throughput_mbps" attributes are specified, the storage object is assigned to an auto-generated QoS policy group.

status

string

Any errors associated with the sample.

Whenever a sample collection is missed but done at a later time, it is back filled with the next closest collection 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 does not have the latest data.
