vgcreate

vgcreate is a command used in Linux to create a volume group, which is a way of combining multiple physical storage devices (like hard drives) into a single, manageable pool. This pool acts as a flexible storage space that allows for easier allocation and resizing of storage for different tasks or files. By grouping disks into a volume group, users can efficiently manage and optimize their storage resources without being limited by the size of individual disks. It's an essential step in setting up advanced storage configurations using Logical Volume Management (LVM).
