Abstract: Techniques are provided for metadata management for enabling automated switchover in accordance with a configuration of storage solution that expresses a preference for either maintaining availability (e.g., a non-zero RPO mode) of the storage solution or avoiding data loss (e.g., a zero RPO mode). In one example, responsive to detecting a switchover trigger event, a node of a local cluster of a cross-site storage solution determines whether performance of an automated switchover from a failed cluster to a surviving cluster of the cross-site storage solution is enabled. Responsive to an affirmative determination, the node selectively proceeds with the automated switchover based on the configuration.

Abstract: Techniques are provided for metadata management for enabling automated switchover. An initial quorum vote may be performed before a node executes an operation associated with metadata comprising operational information and switchover information. After the initial quorum vote is performed, the node executes the operation upon one or more mailbox storage devices. Once the operation has executed, a final quorum vote is performed. The final quorum vote and the initial quorum vote are compared to determine whether the operation is to be designated as successful or failed, and whether any additional actions are to be performed.

Abstract: A method, non-transitory computer readable medium and storage node computing device that reserves one of a plurality of data storage devices that is designated as a coordinator data storage device. A section of the storage cluster that is unowned is identified. Ownership of a subset of the data storage devices that is in the section of the storage cluster is obtained. A determination is made when the subset of the data storage devices includes the coordinator data storage device. The reservation of the coordinator data storage device is released, when the determining indicates that the subset of the data storage devices does not include the coordinator data storage device.

Abstract: A method, non-transitory computer readable medium, and storage node computing device that identifies a subset of a plurality of sections of a shelf that is unowned based on a determined ownership status of a plurality of storage devices hosted by the shelf. Obtained section discriminant data is applied to one of a plurality of ordered storage node identifiers to identify one section of the subset of the sections. Ownership of one or more of the storage devices corresponding to the one section is obtained.

Abstract: Techniques are provided for metadata management for enabling automated switchover. An initial quorum vote may be performed before a node executes an operation associated with metadata comprising operational information and switchover information. After the initial quorum vote is performed, the node executes the operation upon one or more mailbox storage devices. Once the operation has executed, a final quorum vote is performed. The final quorum vote and the initial quorum vote are compared to determine whether the operation is to be designated as successful or failed, and whether any additional actions are to be performed.
