The objects on a 4-node vSAN cluster are assigned a RAID-5 policy. A network outage occurs, causing host one to lose connectivity with the rest of the cluster. Seventy-five minutes have elapsed.
What is the health state of the objects?
A. Reduced availability with no rebuild
B. Non-availability related incompliance (non-compliance)
C. Reduced availability
D. Reduced availability with no rebuild – delay timer
ANSWER: A
Explanation:
Minimum number of hosts required for Raid 5: 2n+1.
Reduced availability – active rebuild: The object has suffered a failure, but it was configured to be able to tolerate the failure.
I/O continues to flow and the object is accessible. vSAN is actively working on re-protecting the object by rebuilding new components to bring the object back to compliance.
Reduced availability with no rebuild: The object has suffered a failure, but VSAN was able to tolerate it. For example: I/O is flowing and the object is accessible. However, VSAN is not working on reprotecting the object. This is not due to the delay timer (reduced availability – no rebuild – delay timer) but due to other reasons. This could be because there are not enough resources in the cluster, or this could be because there were not enough resources in the past, or there was a failure to reprotect in the past and VSAN has yet to retry.
