VERITAS filesystem (VxFS) documentation overview

• extent-based allocation (file storage is allocated as one or more adjacent blocks of data)

• extent attributes (extent allocation policies associated with a file)

• fast filesystem recovery (recovery following a system failure is speeded up by use of a tracking feature called ``intent logging'')

• enhanced security (the Discretionary Access Control (DAC) mechanism)

• support for BSD-style quotas

• support for large files and large filesystems (larger than 2GB)

• enhanced mount options
