STATUS_CLOUD_FILE_PROPERTY_BLOB_CHECKSUM_MISMATCH

Cloud placeholder property metadata is corrupt or stale

This warning is specific to the Cloud Files placeholder model. The on-disk property blob does not match its computed checksum, so the platform cannot trust that metadata as-is.

The file contents may be separate from the placeholder property metadata. Diagnose sync-root provider state, property updates and whether another component modified placeholder metadata incorrectly.

What to inspect

  • Validate provider-written custom properties and their sizes.
  • Check sync-root registration and Cloud Files API call history.
  • Resynchronize placeholder metadata rather than assuming user file content is corrupt.
