Do not use the loopback file system (LOFS) if both conditions in the following list are met:
Sun Cluster HA for NFS is configured on a highly available local file system.
The automountd daemon is running.
If both of these conditions are met, LOFS must be disabled to avoid switchover problems or other failures. If only one of these conditions is met, it is safe to enable LOFS.
If you require both LOFS and the automountd daemon to be enabled, exclude from the automounter map all files that are part of the highly available local file system that is exported by Sun Cluster HA for NFS.
