>
> DiskBalancerYaml.readDiskBalancerInfoFile() currently accepts some malformed
> diskbalancer.info content without failing at the YAML read boundary. For
> example, missing operationalState, missing or unsupported version, or invalid
> persisted configuration values can be read into DiskBalancerInfo and only
> fail later during service initialization, status/report generation, or
> persistence.
> This makes startup failures harder to diagnose and can leave DiskBalancer
> with partially invalid in-memory state. The YAML reader should validate
> persisted data immediately and fail with a clear IOException.
