ERROR_LOG_DEDICATED

The target is a dedicated CLFS log

A dedicated CLFS log is created when the log name identifies only the physical log and no separate stream name is supplied. The dedicated stream owns its physical log, unlike a multiplexed log where several named streams share containers. An API or code path written for multiplexed stream management can therefore be invalid when applied to a dedicated handle.

Record the exact log name and handle-creation path. If the application expected a multiplexed log, check whether the stream suffix was omitted or lost during configuration or string construction. If a dedicated log is intentional, use operations appropriate for its single stream and physical log. Converting an existing deployment by renaming files is not sufficient; dedicated versus multiplexed mode is part of how CLFS creates and addresses the log. Plan migration through supported log creation and client recovery semantics.

What to inspect

  • Inspect the CreateLogFile name and whether a stream component is present.
  • Verify the caller selected APIs and management logic for the actual log type.
  • Recreate or migrate intentionally; do not infer multiplexing from filename layout alone.
