Logging is required for UFS and VxFS cluster file systems. Sun Cluster software supports the following choices of file-system logging:
Solaris UFS logging – See the mount_ufs(1M) man page for more information.
SPARC: Veritas File System (VxFS) logging – See the mount_vxfs man page provided with VxFS software for more information.
Both Solaris Volume Manager and Veritas Volume Manager support both types of file-system logging.
