STATUS_LOG_FULL_HANDLER_IN_PROGRESS

STATUS_LOG_FULL_HANDLER_IN_PROGRESS is a concurrency result, not a second independent storage failure. CLFS management has already accepted a request to make space available for the registered client and may be growing the log or requesting tail movement.

The documented contract is to wait for the client growth-completion callback before issuing another full-log handling request for that client. Retrying immediately produces duplicate control traffic without creating additional capacity.

What to inspect

  • Correlate the status with the first full-log request, its managed-client identity, and the corresponding completion callback.
  • Inspect growth policies, tail callbacks, and pinning state while the request is pending rather than starting another handler.
  • Treat a completed handler that still cannot make space as evidence to investigate pins, reservations, limits, or archive retention.
