Volume Tasks
Resizing a Dynamic Volume
Chapter 4 123
• The Resize Volume task requires either the desired size or the
amount of space to add to or subtract from the volume size.
• A volume containing a file system other than VxFS cannot be
shrunk.
• Shrinking a volume with an unmounted file system can result in
data loss, so a volume containing an unmounted file system cannot
be shrunk.
• When a volume is shrunk, the resulting extra space is returned to
the free space pool.
• When the volume size is increased, sufficient disk space must be
available. When increasing the size of a volume, VxVM assigns the
necessary new space from available disks.
