Consider the following points when you plan cluster file systems.
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.
Process accounting log files - Do not locate process accounting log files on a cluster file system or on a highly available local file system. A switchover would be blocked by writes to the log file, which would cause the node to hang. Use only a local file system to contain process accounting log files.
Although you can create a UNIX domain socket whose name is a path name into the cluster file system, the socket would not survive a node failover.
Any FIFOs or named pipes that you create on a cluster file system would not be globally accessible.
Therefore, do not attempt to use the fattach command from any node other than the local node.
