Returns the description of a specific Amazon EFS file system if either the file system
CreationToken or the FileSystemId is provided. Otherwise, it returns
descriptions of all file systems owned by the caller's Amazon Web Services account
in the Amazon Web Services Region of the endpoint that you're calling.
When retrieving all file system descriptions, you can optionally specify the MaxItems
parameter to limit the number of descriptions in a response. This number is automatically
set to 100. If more file system descriptions remain, Amazon EFS returns a NextMarker,
an opaque token, in the response. In this case, you should send a subsequent request
with the Marker request parameter set to the value of NextMarker.
To retrieve a list of your file system descriptions, this operation is used in an
iterative process, where DescribeFileSystems is called first without the Marker
and then the operation continues to call it with the Marker parameter set to
the value of the NextMarker from the previous response until the response has
no NextMarker.
The order of file systems returned in the response of one DescribeFileSystems
call and the order of file systems returned across the responses of a multi-call iteration
is unspecified.
This operation requires permissions for the elasticfilesystem:DescribeFileSystems
action.
This is an asynchronous operation using the standard naming convention for .NET 4.7.2 or higher.
