At first glance, a single failure might seem trivial. After all, modern ASM configurations are built on pillars of redundancy: normal redundancy, high redundancy, and robust failure groups. A single disk slowing down or a single network path intermittently dropping packets could be masked by the system’s inherent self-healing capabilities. However, the health checker is not an alarmist. It is a sentinel. The designation of “1 new failure” implies a delta from a previous state of health. Something, somewhere, has crossed a threshold from acceptable to aberrant. That one failure is the canary in the coalmine.
