Volume Tasks
Creating a Dynamic Volume
Chapter 4 119
• You cannot use a striped pro volume for a swap volume.
• If a file system is placed on the volume and the Mount at Boot
option is selected, the file system table file is automatically updated.
RAID-5
A RAID-5 volume spreads across two or more disks, and contains parity
information. You have the option of placing a file system on the new
volume.
NOTE
• A RAID-5 volume requires at least three disks. If logging is enabled,
a RAID-5 volume requires at least four disks.
Layout: Choose RAID-5 for the volume layout.
In the Number of Columns field, specify the
number of columns (disks) across which the
volume should be striped. A RAID-5 volume
requires at least three disks (or four disks if
logging is enabled).
To specify a stripe unit size other than the
default, enter the stripe unit size in the Stripe
Unit Size field. To specify a size unit, attach an
s (sectors), k (kilobytes), m (megabytes), or g
(gigabytes) to the size.
Options: • To place a file system on the volume, click
Create a file system and specify the
file system type and mount point in the
New File System dialog box.
• To enable RAID-5 logging for the volume,
select Enable Logging. VxVM adds an
appropriate number of logs to the volume.
• To clear the volume before enabling it for
general use, select Initialize Zero.
