volgroup

The volgroup Kickstart command is optional. It creates a Logical Volume Manager (LVM) group.

Syntax

              volgroup name [OPTIONS] [partition*]
Mandatory options
  • name - Name of the new volume group.
Options
  • partition - Physical volume partitions to use as backing storage for the volume group. At least one partition has to be specified when creating a new volume group.
  • --noformat - Use an existing volume group and do not format it.
  • --useexisting - Use an existing volume group and reformat it. If you use this option, do not specify a partition. For example: 
    volgroup rhel00 --useexisting --noformat
  • --pesize= - Set the size of the volume group’s physical extents in KiB. The default value is 4096 (4 MiB), and the minimum value is 1024 (1 MiB).
  • --reserved-space= - Specify an amount of space to leave unused in a volume group in MiB. Applicable only to newly created volume groups.
  • --reserved-percent= - Specify a percentage of total volume group space to leave unused. Applicable only to newly created volume groups.
Notes
  • Create the partition first, then create the logical volume group, and then create the logical volume. For example: 
    part pv.01 --size 10000
volgroup my_volgrp pv.01
logvol / --vgname=my_volgrp --size=2000 --name=root
  • Do not use the dash (-) character in logical volume and volume group names when installing Red Hat Enterprise Linux by using Kickstart. If this character is used, the installation finishes normally, but the /dev/mapper/ directory will list these volumes and volume groups with every dash doubled. For example, a volume group named volgrp-01 containing a logical volume named logvol-01 will be listed as /dev/mapper/volgrp--01-logvol--01.

    This limitation only applies to newly created logical volume and volume group names. If you are reusing existing ones by using the --noformat option, their names will not be changed.
