Example 1 with DiskState
use of com.yahoo.vdslib.state.DiskState in project vespa by vespa-engine.
the class ClusterStateGeneratorTest method reported_disk_state_not_hidden_by_wanted_state.

// We do not publish disk states for nodes in Down state. This differs from how the
// legacy controller did things, but such states cannot be counted on for ideal state
// calculations either way. In particular, reported disk states are not persisted and
// only exist transiently in the cluster controller's memory. A controller restart is
// sufficient to clear all disk states that have been incidentally remembered for now
// downed nodes.
// The keen reader may choose to convince themselves of this independently by reading the
// code in com.yahoo.vdslib.distribution.Distribution#getIdealStorageNodes and observing
// how disk states for nodes that are in a down-state are never considered.
