11.2. Creating a volume group
Use the 'vgcreate' program:
# vgcreate my_volume_group /dev/hda1 /dev/hdb1
If you are using LVM 1 with
devfs it is essential to use the full devfs name of the
device rather than the symlinked name in /dev
. So the above would be:
# vgcreate my_volume_group /dev/ide/host0/bus0/target0/lun0/part1 \
LVM 2 does not have this restriction.
You can also specify the extent size with this command if the
default of 32MB is not suitable for you with the '-s' switch. In
addition you can put some limits on the number of physical or
logical volumes the volume can have.
