STATUS_LOG_METADATA_CORRUPT

STATUS_LOG_METADATA_CORRUPT identifies corruption in a CLFS metadata file. A CLFS log has a base log file that contains metadata and one or more containers that contain the actual log data, so a metadata failure is not interchangeable with corruption of a particular container block.

CLFS provides validation for metadata and data before archive and after restore. The practical distinction from STATUS_LOG_METADATA_INCONSISTENT is that corruption points to damaged metadata, while an inconsistent result can describe relationships that do not agree even when data can be read.

Treat the base file and containers as one recovery set

  • Preserve the .blf file together with every container before any reset, recreate, or cleanup action.
  • Run CLFS-aware validation or restore procedures against a copy; do not replace only the base file with one from a different log.
  • Correlate the event with storage and shutdown history, but do not infer a single cause from this status alone.
