STATUS_LOG_METADATA_INVALID
STATUS_LOG_METADATA_INVALID means CLFS encountered a metadata file that it cannot recognize as one created by the log file system. The CLFS base log file is the metadata component of a log; it has to match the containers and the log format expected by CLFS.
This is distinct from STATUS_LOG_METADATA_CORRUPT. A corrupt result describes damaged metadata, while this status is about metadata that does not satisfy the requirement of being valid CLFS-created metadata. Renaming an arbitrary file to a base-log name or combining files from unrelated logs will not make a valid recovery set.
Verify provenance before recovery
- Check that the base log came from the same log creation, archive, or restore set as the containers being opened.
- Confirm the intended dedicated or multiplexed log name and stream naming convention before recreating files.
- Use CLFS creation and validation APIs to establish a new log rather than trying to convert unrelated file contents into metadata.
