10 RAID Utility User Guide
This is initially set to the size of the underlying RAID set, but you can enter a smaller
size and save the remaining space to create other volumes.
5 Click Create Volume.
You can start using the volume as soon as its icon appears in the Finder, but maximum
read and write performance isn’t available until the volume is completely initialized.
Until then, the volume status icon in RAID Utility is yellow. Initialization time depends
on the RAID level of the underlying RAID set. To check progress, click Tasks in the left
column of the RAID Utility window.
Expanding a Volume
You can use the command line to expand (add space to) an existing volume from the
available space on the RAID set that hosts it. Expanding a volume doesn’t aect data
already on the volume.
To expand a volume:
Open Terminal and enter the following command: m
$ sudo raidutil modify volume --expand -n volume -s size
where volume is the name of the volume as shown by the raidutil list volumeinfo
command and size is the amount of space you want to add to the volume.
For more information, see the raidutil man page.
Moving a Volume
If you have more than one RAID set, you can move a volume from one RAID set to
another.
To move a volume to a dierent RAID set:
Open RAID Utility, select the volume in the left column, and choose RAID > Move m
Volume.
