Multi-Volume File Systems
Features Implemented Using MVS

Features Implemented Using MVS
You can implement the following features using multi-volume support:
• Controlling where files are stored can be selected at multiple levels so that specific files or file
hierarchies can be assigned to different volumes. This functionality is available in the VERITAS File
System Quality of Storage Service (QoSS) feature (see Chapter 10, “Quality of Storage Service,” on
page 135).
• Placing the VxFS intent log on its own volume to minimize disk head movement and thereby increase
performance. This functionality can be used to migrate from the VERITAS QuickLogT feature.
• Separating Storage Checkpoints so that data allocated to a Storage Checkpoint is isolated from the rest
of the file system.
• Separating metadata from file data.
• Encapsulating volumes so that a volume appears in the file system as a file. This is particularly useful
for databases that are running on raw volumes.
To use the multi-volume file system features, you must install VERITAS Volume Manager and enable the
Volume Set feature.
