Veritas Storage Foundation™ for Oracle 5.0.1 Administrator's Guide

You can now mount the newly created file system.
See “Mounting a file system ” on page 59.
Large file system and large file support
In conjunction with VxVM, VxFS can support file systems up to 8 exabytes in size.
For large database configurations, this eliminates the need to use multiple file
systems because of the size limitations of the underlying physical devices.
Changes implemented with the VxFS Version 6 disk layout have greatly expanded
file system scalability, including support for large files. You can create or mount
file systems with or without large files by specifying either the largefiles or
nolargefiles option in mkfs or mount commands. If you specify the nolargefiles
option, a file system cannot contain files 2 GB or larger.
Before creating a VxFS file system, review the following:
■ See the mount_vxfs (1M) and mkfs_vxfs (1M) manual pages for
detailed information on mounting and creating file systems.
■ See the fsadm_vxfs (1M) manual pages for detailed information
about large files.
Usage notes
To enable large files on a file system that was created without the largefiles option
◆
Use the fsadm command as follows:
# /opt/VRTS/bin/fsadm -F vxfs -o largefiles \
/mount_point
Note: Make sure the applications and tools you use can handle large files
before enabling the large file capability. Applications and system
administration utilities can experience problems if they are not large file
aware.
Multi-volume support
The multi-volume support feature enabled by VxFS Version 6 disk layout allows
several volumes to be represented by a single logical object, known as a volume
set. The vxvset command can be used to create and administer volume sets in
Veritas Volume Manager.
VxFS's multi-volume support feature can be used with volume sets. There are two
VxFS commands associated with multi-volume support:
