Issue/Introduction

This article discusses why the vSAN on-disk format failed, detailing the vSAN On-Disk format version check in the vSAN Health Service and explaining the potential reasons for reporting an error.

Environment

VMware vSAN 7.0.x

VMware vSAN 8.0.x

Cause

The vSAN on-disk format upgrade will fail if the vCenter version is lower than the ESXi version.
