A customer performs a 1-click, non-disruptive upgrade on a 3-node Nutanix cluster. While the CVM on Node A is rebooting, a VM on Node A overwrites an existing block of data. How does Nutanix AOS ensure data integrity during the upgrade?
A.
AOS marks the replica as read only and waits until the original replica is back online to prevent corruption.
B.
AOS writes two copies across the remaining nodes to maintain resiliency
C.
AOS leverages Erasure Coding to maintain resiliency.
D.
AOS only overwrite the available copy and waits until the original copy is back online before restoring resiliency
During a 1-click, non-disruptive upgrade on a 3-node Nutanix cluster, if a VM on Node A overwrites an existing block of data while the CVM on Node A is rebooting, Nutanix AOS ensures data integrity by writing two copies of the data across the remaining nodes. This approach maintains data resiliency by ensuring that multiple copies of the data are available even when one of the nodes is temporarily unavailable.
