ACFS-05935
Oracle Database Error ACFS-05935: ACFS Primary Multi-Node Mount
Description
This error indicates that the Oracle ACFS (Automatic Storage Management Cluster File System) replication primary volume is currently mounted on more than one node simultaneously within a cluster. This is an invalid state for an ACFS replication primary, as it should only be active on a single designated primary node to maintain data consistency and prevent split-brain scenarios. It typically occurs due to clusterware inconsistencies, failed failover attempts, or incorrect manual operations.
Error Message
The ACFS replication primary is mounted on more than one node.
Known Causes
3 known causesClusterware State Inconsistency
The Oracle Clusterware might have an inconsistent view of the ACFS primary volume's mount status across different nodes, leading to simultaneous mounts.
Incomplete Failover/Switchover
A previous ACFS replication failover or switchover operation might have failed or not completed gracefully, leaving the primary mounted on both old and new primary nodes.
Incorrect Manual Mount Operations
An administrator might have manually mounted the ACFS primary volume on multiple nodes simultaneously, bypassing proper clusterware management.
