See “Initializing and starting a volume created using vxmake” on page 303.
Initializing and starting a volume
If you create a volume using the vxassist command, vxassist initializes and
starts the volume automatically unless you specify the attribute init=none.
When creating a volume, you can make it immediately available for use by
specifying the -b option to the vxassist command, as shown here:
# vxassist -b [-g diskgroup] make volume length layout=mirror
The -b option makes VxVM carry out any required initialization as a background
task. It also greatly speeds up the creation of striped volumes by initializing the
columns in parallel.
As an alternative to the -b option, you can specify the init=active attribute to
make a new volume immediately available for use. In this example, init=active
is specified to prevent VxVM from synchronizing the empty data plexes of a new
mirrored volume:
# vxassist [-g diskgroup] make volume length layout=mirror \
init=active
Warning: There is a very small risk of errors occurring when the init=active
attribute is used. Although written blocks are guaranteed to be consistent, read
errors can arise in the unlikely event that fsck attempts to verify uninitialized
space in the file system, or if a file remains uninitialized following a system crash.
If in doubt, use the -b option to vxassist instead.
This command writes zeroes to the entire length of the volume and to any log
plexes. It then makes the volume active. You can also zero out a volume by
specifying the attribute init=zero to vxassist, as shown in this example:
# vxassist [-g diskgroup] make volume length layout=raid5 \
init=zero
You cannot use the -b option to make this operation a background task.
Initializing and starting a volume created using vxmake
A volume may be initialized by running the vxvol command if the volume was
created by the vxmake command and has not yet been initialized, or if the volume
has been set to an uninitialized state.
