VERITAS filesystem (VxFS) documentation overview
SCO OpenServer includes the
``basic'' version of the VERITAS
filesystem (VxFS). Functionality is limited
to the following:
extent-based allocation (file storage is allocated as one or
more adjacent blocks of data)
extent attributes (extent allocation policies associated with
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)
Optionally, you can license the
advanced VERITAS filesystem product (VxFS).
This adds the following functionality to the ``basic''
online administration (defragmentation and resizing of filesystems)
snapshot mounts for online backup
enhanced application interface (for pre-allocation, unbuffered I/O,
and caching advisories.
