Which command is used to display the filesystem parameters such as label or UUID?

The command that is used to display the filesystem parameters such as label or UUID is xfs_admin. This utility is specifically designed for managing XFS filesystems, allowing users to view and modify filesystem parameters. When executed, it can provide important information about the filesystem, including the UUID, which is a unique identifier for the filesystem, and the label, which is a human-readable name.

The other commands listed serve different purposes in Linux storage management. lvcreate is used for creating logical volumes in a Logical Volume Management (LVM) setup. vgcreate is employed to create a volume group in LVM. pvcreate is the command for initializing a physical volume for use with LVM. None of these commands provide information about filesystem parameters like label or UUID, which is why xfs_admin is the correct choice for this specific query.
