Cluster File System Restrictions

• Quotas are not supported on cluster file systems.

• Sun Cluster 3.1 10/03 software does not support the use of the loopback file system (LOFS) on cluster nodes.

• The command umount -f behaves in the same manner as the umount command without the -f option. It does not support forced unmounts.

• The command unlink(1M) is not supported on non-empty directories.

• The command lockfs -d is not supported. Use lockfs -n as a workaround.

• The cluster file system does not support any of the file-system features of Solaris software by which one would put a communication end-point in the file-system name space. Therefore, 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. In addition, any fifos or named pipes you create on a cluster file system would not be globally accessible, nor should you attempt to use fattach from any node other than the local node.

• It is not supported to execute binaries off cluster file systems that are mounted by using the forcedirectio mount option.

• You cannot remount a cluster file system with the directio mount option added at remount time.

  You cannot set the directio mount option on a single file by using the directio ioctl.
