Subnet Health

Subnet Health diagnostics help ensure that the underlying infrastructure that runs MinIO is configured correctly, and is functioning properly. This test is one-shot long running one, that is recommended to be run as soon as the cluster is first provisioned, and each time a failure scenario is encountered. Note that the test incurs majority of the available resources on the system. Care must be taken when using this to debug failure scenario, so as to prevent larger outages. Health...

**NOTE**: When configuring multiple OpenID based authentication providers on a MinIO cluster, any number of Role Policy based providers may be configured, and at most one JWT Claim based provider may be configured.
