vgcreate

Used to create LVM volume groups.

Description

The vgcreate command is used to create LVM volume groups. A volume group (VG) organizes multiple physical volumes into a single entity, shielding the details of the underlying physical volumes. When creating logical volumes on a volume group, specific physical volume information does not need to be considered.

Syntax

vgcreate (option) (parameter)

Options

-l: Maximum number of logical volumes allowed in the volume group;
-p: Maximum number of physical volumes allowed in the volume group;
-s: PE (Physical Extent) size for the physical volumes in the volume group.

Parameters

• Volume Group Name: The name of the volume group to be created;
• Physical Volume List: The list of physical volumes to be added to the volume group.

Examples

Use the vgcreate command to create a volume group named "vg1000" and add physical volumes /dev/sdb1 and /dev/sdb2 to it. Enter the following command at the command line:

[root@localhost ~]# vgcreate vg1000 /dev/sdb1 /dev/sdb2  # Create volume group "vg1000"

The output information is as follows:

Volume group "vg1000" successfully created
