Workflow process with temporary storage resource reservation

摘要

A method involves: detecting a storage resource indication within a workflow request and, in response to the storage resource indication, generating an availability indication. The storage resource indication indicates a storage resource (e.g., by directly or indirectly identifying or selecting the storage resource). The availability indication indicates that the indicated storage resource is not available for subsequent workflow requests. The availability indication is generated prior to allowing the consumer that generated the workflow request to use the storage resource. The workflow request can include a request to allocate a logical storage structure (e.g., a volume or logical disk). The logical storage structure is allocated in response to the workflow request. If the workflow request is denied or expires, the logical storage structure is deleted.

1. A method comprising:
detecting a request for a storage resource, wherein
the request is generated by a requester; in response to detection of the request and prior to approval of the request:
selecting a storage resource from a pool of available storage resources, wherein the selected storage resource will be allocated to the requester if the approval is given andreserving the selected storage resource, wherein
the reserving comprises setting a flag indicating that the selected storage resource is reserved,the reserving removes the selected storage resource from the pool of available storage resources,the requester cannot access the selected storage resource until the request is approved, andany storage resource not in the pool of available storage resources is not available for subsequent requests; subsequent to the reserving, but prior to approving the request, returning the selected storage resource to the pool of available storage resources, wherein
the returning is performed in response to receiving a second request indicating that a higher-priority requester requires the selected storage resource; and approving the second request, wherein
the approval is granted by an approver, andthe approver is not the requester.
