Abstract

Aspects of data management are described. Information for updating software for a data management cluster from a first version associated with a first configuration for operating multiple storage nodes of the data management cluster and a second version associated with a second configuration for operating multiple storage nodes of the data management cluster may be obtained. Based on the information, an update procedure for the data management cluster may be performed, where after a first portion of the update procedure, the first version may be installed on a first set of the storage nodes and the second version may be installed on a second set of the storage nodes. Based on storage nodes in the data management cluster having different software versions, the data management cluster may be operated using the first configuration, the second configuration, or both, during the update procedure.

Description

FIELD OF TECHNOLOGY The present disclosure relates generally to data management, including techniques for configuration management for non-disruptive update of a data management system. BACKGROUND A data management system (DMS) may be employed to manage data associated with one or more computing systems. The data may be generated, stored, or otherwise used by the one or more computing systems, examples of which may include servers, databases, virtual machines, cloud computing systems, file systems (e.g., network-attached storage (NAS) systems), or other data storage or processing systems. The DMS may provide data backup, data recovery, data classification, or other types of data management services for data of the one or more computing systems. Improved data management may offer improved performance with respect to reliability, speed, efficiency, scalability, security, or ease-of-use, among other possible aspects of performance.

DETAILED DESCRIPTION To update the software of a cluster of storage nodes in a non-disruptive manner, an update procedure may serially update subsets (e.g., one or more) of the storage nodes. Accordingly, the storage nodes that are not being updated may continue to support services provided by the cluster of storage nodes throughout the update procedure. Because a non-disruptive update may be used to update storage nodes (or groups of storage nodes) one-at-a-time, multiple configurations (e.g., a first configuration of a first software version and a second configuration of a second software version) may be associated with the cluster of storage nodes during an update procedure. In some examples, it may be preferred for each storage node of the cluster to operate using the same configuration (e.g., an initial configuration) during the non-disruptive update procedure—e.g., for consistency and ease of operation. In other examples, it may be preferred for updated storage nodes to operate using an updated configuration during the non-disruptive update procedure—e.g., to bring performance improvements, provide additional services, or the like. However, permitting the updated storage nodes to use the updated configuration throughout the update (while the non-updated storage nodes use a different configuration) may result in errors during the update procedure. Accordingly, a system that enables updated storage nodes to use certain configuration parameters from the updated configuration (e.g., parameters that support performance improvements or additional services) during an update procedure may be desired. To enable the storage nodes to use a desired set of configuration parameters while the data management cluster is being updated, configurations associated with different software versions may include an indication of whether the configuration (and/or configuration parameters of the configuration) is to be used by a storage node during an update procedure. FIG. 1 illustrates an example of a computing environment 100 that supports configuration management for non-disruptive update of a data management system in accordance with aspects of the present disclosure. The computing environment 100 may include a computing system 105, a data management system (DMS) 110, and one or more computing devices 115, which may be in communication with one another via a network 120. The computing system 105 may generate, sto
