Abstract
Disclosed herein is a technique to automatically re-bind applications and storage volumes during recovery from planned outage or platform failure and disaster recovery. Such implementations can involve managing volume management information that maps volume claim information with a logical volume identifier associated with persistent volume information; and for receipt of a request for a new volume, referencing the volume management information to retrieve an associated logical volume identifier and the persistent volume information based on the volume claim information associated with the request; and providing the retrieved persistent volume information to a volume provisioning function.
Claims9
A method, comprising:
- managing volume management information that maps volume claim information with a logical volume identifier associated with persistent volume information;
- and
- for receipt of a request for a new volume:
- referencing the volume management information to retrieve an associated logical volume identifier and the persistent volume information based on volume claim information associated with the request;
- and
- providing the retrieved persistent volume information to a volume provisioning function,
- wherein the referencing the volume management information to retrieve the associated logical volume identifier and the persistent volume information based on the volume claim information associated with the request comprises:
- determining whether a corresponding data exists in the volume management information associated with a claim name from the persistent volume information;
- for a determination that the corresponding data exists, retrieving the associated persistent volume information comprising persistent volume identifier and persistent volume attributes, from the volume management information.
A method, comprising:
- managing volume management information that maps volume claim information with a logical volume identifier associated with persistent volume information;
- for receipt of a request for a new volume:
- providing temporary persistent volume information to a volume provisioning function, and
- for the volume provisioning function deploying a persistent volume metadata responsive to the logical volume identifier and the persistent volume information:
- during a deployment of a persistent volume;
- referencing the volume management information to retrieve an associated logical volume identifier and the persistent volume information based on the volume claim information;
- and
- overwrite persistent volume metadata attributes with retrieved persistent volume attributes in the volume management information.
A method, comprising:
- managing volume management information that maps volume claim information with a logical volume identifier associated with persistent volume information;
- generating a persistent volume metadata using the logical volume identifier and the persistent volume information in the volume management information prior to receipt of a request for a new volume, and
- performing automatic binding of a persistent volume claim to the persistent volume metadata.
