vgcreate - Create a Volume Group (VG)

The vgcreate command is a part of the Logical Volume Manager (LVM) toolset and is used to create a Volume Group (VG) by combining one or more Physical Volumes (PVs). This command should be executed as the superuser (root) because it involves configuring storage at the system level.

The basic syntax for the vgcreate command is as follows:
vgcreate [OPTIONS] VG_NAME PV_NAME1 [PV_NAME2 ...] .

Here:

• "VG_NAME" is the name of the volume group you want to create.
• "PV_NAME1"," PV_NAME2", etc., are the names of the physical volumes (PVs) that you want to include in the volume group.

Some commonly used options for the vgcreate command include:

• -l: List detailed information about the creation of the volume group.
• -p: Specify the maximum number of physical volumes that are allowed to be added to the volume group.
• -s: Specify the size of physical extents (PEs) within the volume group.

This command creates a volume group named "db_vg" and includes the specified physical volumes in it.

Creating volume groups is an essential part of LVM management, allowing you to organize and manage your logical volumes effectively.
