Error: "vSAN datastore is not compatible with the policy configured for vSAN Performance Service"

Products

• VMware vSAN

Issue/Introduction

• vSAN performance service fails to enable.
• Skyline health messages include:
  • "vSAN datastore is not compatible with the policy configured for vSAN Performance Service"
  • "Issue: Performance service is turned on in cluster configuration, but it is not enabled yet."
  • "Performance service is turned on in cluster configuration, but it is not enabled yet, which might be caused by network partition or vSAN datastore is not compatible. "

Environment

8.0U3

Cause

• You do not need to assign every vSAN host to a fault domain.
• If you decide to use fault domains to protect the vSAN environment, consider creating equal sized fault domains.
• Configure a minimum of three fault domains in the vSAN cluster.
• For best results, configure four or more fault domains.

Resolution

• Change the vSAN Domain Layout from a single domain with multiple servers to multiple domains with one server per domain.
• See Managing Fault Domains in vSAN Clusters
