> it tells her its hard drive is full despite seeming to have 16 gigabytes free. If she has a lot of small files she might have run out of inodes [0] which will report "no space left on device" when trying to create a new file, although there's still space left. Inodes store a file's attributes. In ext4 they're limited to total disk space / 16Kb, so a lot of files <16kb will cause trouble. You can check inode usage via `df -i`. 0: https://en.wikipedia.org/wiki/Inode https://en.wikipedia.org/wiki/Inode
