Detailed help on each option may be obtained by pressing the F1 or “!” keys.
At the upper-right-hand corner of the screen is a box containing information regarding the current size and free
space within the volume group this logical volume is assigned to, and information on the original and minimum
size of the logical volume. This information is helpful to determine how much free space is available in the
volume group for enlarging this logical volume (and its corresponding filesystem, if any) or how much space is
freed by reducing it to the minimum size required to restore the data.
The “Create this LV?” field will be “Create Option” if installing the system. The options for this field vary
depending on whether you are installing the system or recreating the logical volume on an active system:
1. Press “y” to create and restore (if installing the system) this logical volume.
2. Press “n” if you do not want to create or restore the logical volume.
3. Press “c” (only available if installing the system) if you want to create the logical volume but do not want to
restore the data.
Changes to the following fields will change the amount of space used in the volume group for this logical
volume and will change the volume group space reflected in the upper-right box on the screen:
1. Volume group: if you move the LV to a different volume group, the information in the VG Space Avail field
will reflect the new volume group.
2. LPs: This changes the number of logical partitions used by the logical volume. This number times the
number of copies equals the number of PPs (physical partitions) used in the volume group. Changing this
value will also change the value of the Megabytes field below.
3. Megabytes: Likewise, when changing this field, the LPs field will be changed accordingly, and will also
change the number of PPs used in the volume group. If the number of megabytes selected is not evenly
divisible by the partitions size of the volume group, it will be rounded up to the next partition size.
4. Copies: Increasing the number of copies by 1 effectively doubles the number of PPs used by this logical
volume, and will be reflected in an increase to the number of PPs used in the volume group.
By default, the logical volume may be placed on any physical volume available in the volume group. You may
also select the physical volumes on which to place the logical volume by moving to the Physical Volumes field
and pressing the F4 or “$” key. When doing so, a list of physical volumes within the selected volume group will
