STATUS_LOG_FULL

STATUS_LOG_FULL means the physical CLFS log has exhausted space for the requested work. It is not simply a statement about free bytes on the volume: the relevant capacity is the set of usable containers after tail, archive, reservation, and management-policy constraints are applied.

For a managed log, CLFS can try to add containers or request tail movement. That distinguishes this result from STATUS_LOG_PINNED, where retained data prevents recycling, and from STATUS_LOG_FULL_HANDLER_IN_PROGRESS, where the managed response is already running.

What to inspect

  • Record total and free log space, current base and tail LSNs, container inventory, archive mode, and outstanding reservations.
  • Determine whether the caller is a registered managed client before asking CLFS management to grow the log or advance client tails.
  • Do not delete individual containers to make room; reconcile the physical-log state through documented CLFS container and archive operations.
