A few minutes before I wondered why no upload to my server worked — the problem was: There is no free space left on the 15GB / partition. I found 2 files named "vx" (7GB) and "v"(2GB) in the root directory, but I have no idea where they come from and if they are important…

Do you know where they could have come from and if I can delete them?

The server is running some basic processes like php, mysql, webdav etc. thx

Run the command file vx. and file x to see what type of file they are. – Zoredache Aug 21 '13 at 21:09
btw can anyone explain why the qeustion has been voted down? Have I missed some netiquette or is it because of my dumbness (which I could understand ^^) – Luke Aug 21 '13 at 21:19
Delete them anyway.. If someone's dumb enough to leave them there, they deserve to lose them. – Tom O'Connor Aug 21 '13 at 21:27
I suspect because your quest asking something that nobody else in the world could know. If you don't know where your files came from, why should we know? If you aren't sure what something is, delete it. If it was important, then restore it from your backup. (You DO make backups right?) – Zoredache Aug 21 '13 at 22:05
Umm… yes, now I see, it was very unclear, sorry for that ;) – Luke Aug 25 '13 at 20:46

Sounds like someone was typing tar with the options in the wrong order

tar -czfv archive.tgz archive/

creates a "v" file for me (and no output) where you probably meant

tar -czvf archive.tgz archive/

You can try

 tar -tvzf my_tar.tar.gz >/dev/null

and see if you get a file listing to verify.
