- What is tmpfs and why is it using most of my hdd space?
By coincidence your tmpfs use is about the same size as the unassigned space I can see how you would assume that is where your HDD is being used up if you don't know how the filesystems work As explained by Florian, tmpfs are RAMdrives and have nothing to do with your HDD udev is the device path, it also is not related to HDD space
- Where does tmpfs come from and how is it mounted
The “device column” shows tmpfs because many configurations are unimaginative and use the same string for the device name as for the filesystem type The tmpfs driver ignores the “device name” since it doesn't load data from anywhere These filesystems are created by mounting them and are destroyed by unmounting them
- tmpfs usage and resizing - Unix Linux Stack Exchange

- Why does df contain several tmpfs entries? - Unix Linux Stack Exchange
tmpfs isn’t a pseudo file system, it’s a real file system that stores its contents in virtual memory The difference is that pseudo file systems offer a representation of something else, whereas real file systems store artefacts directly Significantly for df, pseudo file systems can’t run out of storage in the usual way, because data can’t be added to them directly Real file systems
- filesystem - What is udev and tmpfs - Ask Ubuntu

- tmpfs - How to create and mount a RAM disk at computer startup? - Unix . . .

- (How) can I create a tmpfs as a regular (non-root) user?
Linux provides a tmpfs device which any user can use, dev shm It is not mounted to a specific directory by default, but you can still use it as one Simply create a directory in dev shm and then symlink it to wherever you want You can give the created directory any permissions you choose, so that other users can't access it This is a RAM backed device, so what's there is in memory by
- tmp on tmpfs: fstab vs tmp. mount with systemd
I always disable tmp being a tmpfs because it takes away from valuable RAM especially on systems like Raspberry Pi Thus, I use systemctl mask tmp mount to disable it on systemd Also, I don't want my tmp to be cleared with every boot nor do I want to think about storing semi-temporary files in var tmp Temporary to me means "not system critical" but it doesn't mean "unnecessary between
