What is the purpose of the command xfs_admin in Linux?

The command xfs_admin is specifically designed for modifying parameters of an XFS filesystem, which is a high-performance file system used primarily in Linux. When you execute xfs_admin, it allows users to change various attributes, such as the filesystem label, user quota settings, and other configuration attributes that govern how the filesystem operates.

This tool is used for administrating the XFS filesystem effectively, enabling file system administrators to customize aspects of the filesystem without needing to reformat it or lose existing data. Since the command's primary function revolves around adjusting filesystem parameters, this aligns directly with the stated purpose of option B. The other options pertain to volume management operations that are related but are not the focus of the xfs_admin command, highlighting the importance of understanding the specific capabilities of filesystem administration tools in Linux.
