Relocating directory /export/home to a bigger filesystem

My 2GB /export/home/ directory is almost 100% full

df -k | grep /export/home
/dev/vx/dsk/rootdg/vl73 2031711 1951009 19751 99% /export/home

I intend to relocate it to a different 4GB filesystem late at night when there is no user on the system.

How do I go about it using ufsdump & ufsrestore ?

Kind Regards

First off, you don't use ufsdump/ufsrestore - your filesystem is controlled by Volume Manager - all you need to do is grow the filesystem - see the man page for vxresize or vxassist.

From Sunsolve:

To resize a UFS (grow only) or VXFS file system using Volume Manager 3.x/4.x,
you can use the vxresize command via the command line. This command will grow a
file system AND its underlying volume.

Here is an example of the vxresize command in its basic syntax:

# vxresize -g diskgroup_name volume_name new_length

To determine the amount of space available for a resize, you can use the
vxassist command:

# vxassist -g diskgroup_name maxgrow volume_name

The new_length can be specified as either the total volume length, or as an
addition or subtraction to the current size:

# vxresize -g diskgroup_name volume_name +additional_space

You can also use this command to specify which disks to use for the resize:
To find the space available on these disks:

# vxassist -g diskgroup_name maxgrow volume_name disk01 disk02

# vxresize -g diskgroup_name volume_name new_length disk01 disk02

For additional restrictions on the use of this command please reference the
Veritas Volume Manager Administration guide for the version you are running.

For information on resizing a file system by the CLI for Volume Manager < 3.0,
see Infodoc ID 14881.

if using vxassist you must make sure that you also grow the filesystem to match the new volume, use vxresize and you won't need to worry about that.
