Abstract: Aspects of data management are described. A cluster-level state machine may be instantiated for an update procedure for updating software for a cluster of storage nodes, where the update procedure may be configured to serially update the plurality of storage nodes. The cluster-level state machine may be configured to monitor the update procedure at a cluster level. One or more node-level state machines may be instantiated for the update procedure, where the one or more node-level state machines may be configured to monitor the performance of the update procedure at a storage node level. During an update procedure, the state of the cluster-level state machine may reflect a state of the cluster of storage nodes and the state of a node-level state machine may reflect a state of a respective one or more storage nodes.

Abstract: Aspects of data management are described. Information for updating a cluster of storage nodes to a second version may be obtained. Based on obtaining the information, a cluster-level precheck procedure may be performed prior to initiating an update procedure for the cluster of storage nodes. Also, during the update procedure, a node-level precheck procedure may be performed prior to initiating an update of a storage node to determine whether the storage node is in a state for successful update. Based on a result of the node-level precheck, a determination of whether to delay the update of the storage node may be made.
