About file system resizing
A file system is assigned a specific size as soon as it is created; the file system may
become too small or too large as changes in file system usage take place over time.
VxFS is capable of increasing or decreasing the file system size while in use. Many
competing file systems can not do this. The VxFS utility fsadm can expand or
shrink a file system without unmounting the file system or interrupting user
productivity. However, to expand a file system, the underlying device on which
it is mounted must be expandable.
VxVM facilitates expansion using virtual disks that can be increased in size while
in use. The VxFS and VxVM packages complement each other to provide online
expansion capability. Use the vxresize command when resizing both the volume
and the file system. The vxresize command guarantees that the file system
shrinks or grows along with the volume. You can also use the the vxassist
command combined with the fsadm_vxfs command for this purpose; however,
Symantec recommends that you use the vxresize command instead.
See the vxresize(1M) manual page.
