Question
A user cannot save large files to a directory on a Linux server that was accepting smaller files a few minutes ago. Which of the following commands should a technician use to identify the issue?
- A. pvdisplay
- B. mount
- C. df -h Correct
- D. fdisk -l
Explanation
Small files still save but large ones fail, so the file system holding the directory is most likely running out of free space. The df -h command shows used and available space for each mounted file system in human-readable units. pvdisplay shows LVM physical volume details, mount lists mount points and options, and fdisk -l lists partition tables, so none of them directly shows how much free space is left.
