STATUS_LOG_POLICY_ALREADY_INSTALLED
STATUS_LOG_POLICY_ALREADY_INSTALLED means an attempt was made to install a CLFS management policy whose type is already present for the log. CLFS policy-based management covers such controls as growth, shrink behavior, maximum and minimum size, container naming and size, and log-tail behavior.
The status is about a duplicate policy type, not proof that the existing policy is wrong. It differs from STATUS_LOG_POLICY_CONFLICT, where a policy prevents an operation, and from STATUS_LOG_POLICY_INVALID, where the installed policy set itself is invalid.
Query before replacing policy state
- Query the policy of the requested type before installing another one.
- Coordinate policy updates among clients that share the same physical log; they are all subject to the same policies.
- Use the documented remove or replace path only after recording the existing policy and its operational effect.
