Creating an Asynchronous Task for a File System
Function
This API is used to create an asynchronous task for a file system. Only tasks for querying directory usage can be created. Such tasks are also referred to as DU tasks. The value of feature in the API request path is dir-usage.
Constraints
This API is only supported for file systems created after August 1, 2023. If there are 10 tasks being executed, no more task can be created. You are advised not to submit five or more requests at a time, or the file system performance may be affected. It takes a long time to query an oversized directory. Do not submit the request repeatedly. The value of feature in the API request path can only be the following:
- dir-usage
This API is only supported for the following types of file systems:
- 20 MB/s/TiB
- 40 MB/s/TiB
- 125 MB/s/TiB
- 250 MB/s/TiB
- 500 MB/s/TiB
- 1,000 MB/s/TiB
For SFS Turbo Standard, Standard-Enhanced, Performance, Performance-Enhanced file systems, use the API for querying the file system directory usage.
