Resolution
- What does the HCI Cluster Health - vSAN disk format version compatibility check do?
This health check validates if any on-disk format version is higher than the supported disk format version of the hosts in the cluster.
The highest supported disk format version for all hosts should be not lower than any of the existing on-disk format version in the vSAN cluster.
The highest supported disk format version for all hosts should be not lower than any of the existing on-disk format version in the vSAN cluster.
- What does it mean when it is in an error state and how to fix?
If this check fails, it means that there are incompatible disk format versions in hosts, which may cause network partition when forming a vSAN cluster.
The table included in this health check will report the host and disks with issues, and with some remediation recommendation.
To fix such an issue you can either upgrade software version on the hosts with lower supported disk format version, or form the cluster with hosts with compatible disk format which means remove the host with the higher disk format version.
