Create a qtree in a FlexVol or FlexGroup volume

08/29/2024 Contributors

POST /storage/qtrees

Introduced In: 9.6

Creates a qtree in a FlexVol 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.

Recommended optional properties

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.

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:

For example, if the aggregation of data over multiple nodes fails then any of the partial errors might be returned, "ok" on success, or "error" on any internal uncategorized failure. 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.
