The CDS feature is also referred to as Portable Data Containers.
Note To use the CDS feature, a VxFS license is required that enables CDS.
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 VERITAS Volume Manager.
There are two new VxFS commands associated with this feature:
Multi-volume file systems include the following functions in the MVS API:
Note To use the MVS feature, a VxFS license is required that enables MVS.
Large File Systems and Large File Support
The 4.1 release is the first VxFS release to support a new disk layout Version 6 that enables the
creation of files and file systems up to 256 TB in size. File systems created on VxFS 4.1 will by
default use the Version 6 disk layout. File systems larger than 1 TB can be created only on 64-bit
kernels and must be created on VERITAS Volume Manager volumes. The maximum file system
size on a 32-bit kernel is still 1 TB. A 32 TB file system requires a 2 K block size, a 64 TB file
system requires a 4 K block size, and a 128 TB or larger file system requires an 8 K block size. File
systems over 32 TB are called extra large file systems and require a license to create.
An online conversion utility, vxupgrade, is provided to upgrade existing disk layouts to Version
6 on mounted file systems.
VxFS has been tested on file systems up to 9.5 TB with physical storage. Using a virtual disk driver
that emulates large devices, file systems up to 256 TB have been tested.
