Veritas File System 5.0 Administrator's Guide (September 2006)

enable communication services and provide storage resources. These products
are packaged with VxFS in the Storage Foundation Cluster File System to provide
a complete clustering environment.
See the Veritas Storage Foundation Cluster File System Administrator's Guide.
To be a cluster mount, a file system must be mounted using the mount –o cluster
option. File systems mounted without the –o cluster option are termed local
mounts.
CFS functionality is separately licensed.
Cross-platform data sharing
Cross-platform data sharing (CDS) allows data to be serially shared among
heterogeneous systems where each system has direct access to the physical devices
that hold the data. This feature can be used only in conjunction with Veritas
Volume Manager (VxVM).
See the Veritas Storage Foundation Cross-Platform Data Sharing Administrator's
Guide.
File Change Log
The VxFS File Change Log (FCL) tracks changes to files and directories in a file
system. The File Change Log can be used by applications such as backup products,
webcrawlers, search and indexing engines, and replication software that typically
scan an entire file system searching for modifications since a previous scan. FCL
functionality is a separately licensed feature.
See “About the File Change Log file” on page 108.
Multi-volume support
The multi-volume support (MVS) feature allows several volumes to be represented
by a single logical object. All I/O to and from an underlying logical volume is
directed by way of volume sets. This feature can be used only in conjunction with
VxVM. MVS functionality is a separately licensed feature.
See “About multi-volume support” on page 116.
Dynamic Storage Tiering
The Dynamic Storage Tiering (DST) option is built on multi-volume support
technology. Using DST, you can map more than one volume to a single file system.
You can then configure policies that automatically relocate files from one volume
