/tmp/ is somehow out of space and contains an irremovable file
When tab-autocompleting in terminal, I'm getting the error:
-bash: cannot create temp file for here-document: No space left on device
This would appear to mean that /tmp/ is full, but it's mounted on my hard disk, which itself has lots of space left.
/tmp only contains one thing: a folder called /tmp/.mount_VCeNjK/.
I can't find out anything about it, because even sudo and su can't chmod it, read it, umount it, rm it, or stat it. They complain about permissions and say that it's busy.
What can I do? I'm nothing without my autocomplete.

/tmpis usually mounted in memory since it'stmpfsfilesystem. Rundfcommand, see what's the actual usage it reports. You can further analyze what takes up most memory viancduor justdurunning over/tmp. There's also a way to increase/tmpsize: askubuntu.com/a/199708/295286

sudo lsof +D /tmp/.mount_VCeNjK/will show you which processes have the directory (or files and directories underneath) open. When these processes finish (or arekilled), you'll probably be able tosudo rm -rf. But be aware that this will have side effects that I can't predict, so you MUST proceed with care.

@SergiyKolodyazhnyy Most Linux systems don't actually mount/tmpusing tmpfs, seemount | grep tmpfor an example.

@KristopherIves Fair enough, but I wouldn't say "most", I'd say "some" do (also this ). As far as Ubuntu goes, I had/tmpmounted as tmpfs in previous releases of Ubuntu, hence assuming it's default. Could have happened that I mounted it there myself at some point, but I don't recall doing so. There's apparently discussion on centos forum which suggests it may depend on amount of RAM

It's possible (although not common) for a ext4 file system to have remaining space but nothing reserved for inode meta data, essentially meaning the disk is "full" of a very large (millions) of small individual files.
You can run df -i to see the "IUse%" metric of a file system.
