You are surveying an unfamiliar server's storage. Type the command, with no options and no arguments, that lists all block devices as a tree showing each device's size, type and mount point.
LPIC-1 Exam 101-500, objective 104. Devices, Linux filesystems, filesystem hierarchy standard easy
Machine-checked — no person has signed for it. This question was read against the source cited below by an automated pass, which found no contradiction. That is a weaker claim than it sounds: the same kind of process wrote the question, so it can confirm its own mistake.
Treat it as a good draft rather than as settled fact, and read the source below before you rely on it. It is not used in mock exams here — only questions a person has signed for are.
How these questions are written — where each question comes from, what the verification ledger records, and what happens when one is found wrong.
Answer
Type the answer.
Accepted answers
lsblk/usr/bin/lsblk/bin/lsblk
Case sensitive — Linux is, and grading LS as ls would teach a falsehood.
Why
lsblk reads sysfs and reports block devices with their partitions indented beneath them, giving NAME, MAJ:MIN, RM, SIZE, RO, TYPE and MOUNTPOINTS by default. Adding -f replaces the size columns with filesystem type, label and UUID, which is the usual way to gather what an fstab entry needs. Unlike df, lsblk shows devices that carry no filesystem or are not mounted at all.

Reading one question is not practice. The trainer will draw a short set from objective 104 and space the ones you get wrong.

- A new disk /dev/sdb has no partition table at all. Which command writes an empty GPT partition table onto it without dropping you into an interactive editor? machine-checked
- You need the partition /dev/sdc1 on a USB stick to carry a FAT32 filesystem so that Windows machines can read and write it. Which command creates it? machine-checked
- You have just run `mkswap /dev/sdb2`. Which command makes the kernel start using that swap area immediately, without a reboot? machine-checked
- Why is it dangerous to run e2fsck against an ext4 filesystem that is currently mounted read-write? machine-checked
- On an ext4 filesystem at /dev/sda1 you want an automatic check to be forced after every 30 mounts. Which command sets that? machine-checked
- `df -h /var` reports the filesystem 100% full, but `du -sh /var` accounts for only about half that space. Nothing is hidden under a mount point. What is the most likely explanation? machine-checked
