1. A method for managing performance of application I/O in a cluster, the method comprising: monitoring application I/O on paths in the cluster, and on detection of the application I/O failing intermittently on the paths in the cluster, marking the paths in the cluster detected as flaky: determining whether paths from a first host to a node in the cluster are flaky; assigning the paths in the cluster marked flaky to a standby mode; and on detection of a path of the paths being flaky from the node, initiating a failover mechanism for an application I/O from the node to a second node in the cluster to transmit the application I/O in the cluster using zoning information in the cluster.
