Method for finding failing components in a large distributed storage system connectivity

Abstract:

Embodiments of the present systems and methods may provide techniques for finding failing components in a distributed storage system. For example a method may comprise measuring problems and health of a plurality of physical and logical components in a distributed storage system, the plurality of physical and logical components forming nodes of the distributed storage system, and generating a graph of the nodes organized in a plurality of hierarchical levels, generating, for each node in the graph, a score summarizing the measured problems and health of the node, determining a highest score at a highest hierarchical level of the graph and determining the associated node as a failing component at a most significant level.
