Oracle Database Error ACFS-03299: ACFS Operations During Rolling Migration
Description
This error indicates that an attempt was made to freeze or thaw an ACFS (ASM Cluster File System) file system while the Oracle Clusterware or Grid Infrastructure is undergoing a rolling migration. During a rolling migration, the cluster's state is transitional, and operations that require a stable, consistent cluster-wide view, such as ACFS freeze/thaw, are temporarily restricted to maintain system integrity and prevent data corruption.
Error Message

Known Causes
3 known causesActive Grid Infrastructure Migration
The Oracle Grid Infrastructure (Clusterware and ASM) is currently undergoing a rolling upgrade, patching, or maintenance operation, which temporarily restricts ACFS operations.
Database Rolling Maintenance

Cluster State Inconsistency
The cluster is in a transitional or inconsistent state due to the ongoing rolling migration, preventing operations that require a stable, synchronized cluster view.
