Preparing Shared Storage
In some systems, the logical volume manager is
available to create the necessary disk partitions. When using raw
devices, carefully partition the disks to insure partitions are
sized adequately. The LVM (Logical Volume Manager) is very useful
and makes the management of raw devices more flexible.
Use pvcreate
to create a physical volume for use by the logical volume
manager.
$ pvcreate -d
/dev/sda
For a single partition on a multi-partition
drive, use the partition designator such as
/dev/sda1.
Use vgcreate
from a root session to create a volume group for the drive or
for the partition that will be used for the raw.
$ vgcreate -l
256 -p 256 -s 128k /dev/sda
The above command allows 256 logical partitions
and 256 physical partitions, with a 128K extent size.
