When a WAFL inconsistency is detected, the first step is to stabilize the system before attempting any repairs or recovery.
Stabilize the System:
Ensure that the system is not experiencing ongoing hardware or software issues.
Avoid making changes to the affected aggregate or volume until the system is stable.
Assess the Impact:
Determine which aggregates or volumes are affected and the severity of the inconsistency.
Steps to Handle WAFL Inconsistency:
A. Run wafliron:
Running wafliron should only be done after stabilizing the system and under guidance from NetApp Support.
C. Force offline the affected aggregate:
Forcing an aggregate offline without proper assessment can lead to data loss.
D. Run a dump to null:
Dumping data is not relevant for resolving a WAFL inconsistency.
Why Other Options Are Incorrect:
"NetApp WAFL Troubleshooting Guide" specifies that stabilization is the first step after detecting inconsistencies.
NetApp Support documentation provides guidelines for handling WAFL inconsistencies safely.
