Abstract: A cluster network environment may comprise a plurality of nodes configured to perform various tasks, such as data I/O, storage, backup, etc. It may be advantageous to improve disaster recovery and reliability by creating backups that may be used to restore the cluster network environment and/or nodes therein. Accordingly, one or more techniques and/or systems are disclosed for restoring a cluster network environment and/or nodes therein. In particular, cluster configuration data, which may be stored in a healthy node or at a remote source, may be used to restore a node affected by an integrity loss. If the integrity loss affects the cluster network environment (e.g., a majority of healthy nodes are lost), then a new cluster network environment may be created from a healthy node or a restored healthy node. The creation of the new cluster network environment may be based at least in part on cluster configuration data.

Abstract: A variety of complex multiphase tasks may execute within a cluster network environment. It may be advantageous to track and analyze the processing of such multiphase tasks. Accordingly, one or more techniques and/or systems are disclosed for tracking the processing of a multiphase task within a cluster network environment. In particular, runtime support for recording task processing annotations may be embedded into a multiphase task using an analysis model. The analysis model may specify task processing annotations that are to be recorded during one or more phases of processing the multiphase task. During execution, task processing annotations may be recorded and associated with corresponding phases of the multiphase task. Task processing annotations may be aggregated into aggregated statistical task data. The aggregated statistical task data may be used to generate views of statistical data, which may provide insight into the cluster network environment (e.g., problematic nodes, bottlenecks, etc.).

Abstract translation: 各种复杂的多相任务可以在集群网络环境中执行。 跟踪和分析这种多相任务的处理可能是有利的。 因此，公开了一种或多种技术和/或系统，用于跟踪群集网络环境内的多相任务的处理。 特别地，用于记录任务处理注释的运行时支持可以使用分析模型嵌入到多相任务中。 分析模型可以指定在处理多相任务的一个或多个阶段期间要记录的任务处理注释。 在执行期间，任务处理注释可被记录并与多相任务的相应阶段相关联。 任务处理注释可以聚合成聚合的统计任务数据。 聚合的统计任务数据可以用于生成统计数据的视图，其可以提供对集群网络环境的洞察（例如，有问题的节点，瓶颈等）。
