Using the diskgroup names displayed by the previous command, list the disk
groups that have volumes on which FastResync is set:
# vxprint -g diskgroup -F "%name" -e "v_fastresync"

# vxvol -g diskgroup set fastresync=off volume
Configuring Veritas File System
After installing Veritas File System, you can create a file system on a disk slice or
Veritas Volume Manager volume with the mkfs command. Before you can use this
file system, you must mount it with the mount command. You can unmount the
file system later with the umount command. A file system can be automatically
mounted at system boot time if you add an entry for it in the following file:
/etc/fstab
The Veritas-specific commands are described in the Veritas File System guides
and online manual pages.
See the Veritas File System Administrator’s Guide.

By default, you must have superuser (root) privileges to use the
/opt/VRTS/bin/vxtunefs command. The vxtunefs command is a tool that lets
you change caching policies to enable Cached Quick I/O and change other file
