By default, the vxassist
make
command creates a concatenated volume that uses one or more sections of disk space. On a fragmented disk, this allows you to put together a volume larger than any individual section of free disk space available.
Note
To change the default layout, edit the definition of the layout
attribute defined in the /etc/default/vxassist
file.
If there is not enough space on a single disk, vxassist
creates a spanned volume. A spanned volume is a concatenated volume with sections of disk space spread across more than one disk. A spanned volume can be larger than any disk on a system, since it takes space from more than one disk.
To create a concatenated, default volume, use the following form of the vxassist
command:
# vxassist [-b] [-g
diskgroup] make
volume
length
Note
Specify the -b
option if you want to make the volume immediately available for use. See Initializing and starting a volume for details.
For example, to create the concatenated volume voldefault
with a length of 10 gigabytes in the default disk group:
# vxassist -b make voldefault 10g
