pvcreate - Creating Physical Volumes (PV) in LVM

pvcreate is a command in the LVM (Logical Volume Manager) context that is used to initialize a disk or partition and convert it into a physical volume (PV). This operation is a fundamental step in setting up an LVM storage configuration. The pvcreate command must be executed by the root user or a user with sudo privileges.

The basic syntax of the pvcreate command is pvcreate [OPTIONS] DEVICE_NAME.

Some commonly used options for the pvcreate command include:

• -f ： Force the creation of a PV even if the device is already in use.
• -y ： Answer "yes" to all prompts without requiring confirmation.
• -U UUID ： UUID: Specify a specific UUID for the PV.
• -v : Display verbose output, showing the conversion process.。
