A system administrator needs to quickly document the storage layout of a new Linux server. They require a command that displays all block devices, including physical disks, partitions, and logical volumes, in a clear, hierarchical format to easily visualize their relationships. Which of the following commands is the most suitable for this specific task?
The correct command for this scenario is lsblk. The lsblk command is designed to list block devices in a tree-like format, which clearly shows the hierarchical relationship between disks, the partitions on those disks, and any logical volumes or RAID arrays built upon them. blkid is used to display attributes of block devices, such as their UUIDs and filesystem types, but it does not show the hierarchical structure. fdisk -l and parted -l are used to display partition tables but do not present the information in the intuitive, nested tree structure that lsblk provides, making it harder to visualize complex storage setups like those involving LVM.
