CFS recovery
The vxfsckd daemon is responsible for ensuring file system consistency when a node crashes that was a primary node for a shared file system. If the local node is a secondary node for a given file system and a reconfiguration occurs in which this node becomes the primary node, the kernel requests vxfsckd on the new primary node to initiate a replay of the intent log of the underlying volume. The vxfsckd daemon forks a special call to fsck that ignores the volume reservation protection normally respected by fsck and other VxFS utilities. The vxfsckd can check several volumes at once if the node takes on the primary role for multiple file systems.
After a secondary node crash, no action is required to recover file system integrity. As with any crash on a file system, internal consistency of application data for applications running at the time of the crash is the responsibility of the applications.
