Sep 1, 2025September 2025: Focused on stabilizing the disk decommission workflow in cubefs/cubefs by preventing false alert triggers and ensuring accurate post-decommission signaling. The fix resolves a mis-triggering issue where disk decommission success alerts could be fired for disks previously marked bad if they were part of a successful decommission. The change improves alert accuracy, reduces noise, and strengthens operator trust in the monitoring system. Business impact includes lower alert fatigue and reduced risk of misinterpretation during decommission operations.
