ark "No space available on device" error despite 300gbs of space

when i try to extract a 2 gig .rar file in ~/Downloads to my ~/Downloads/w using the ark gui i get the error:
No space available on device ‘/home/nice/Downloads/w/file’

the output of df -h is:

My ark using tmpfs mounted in /tmp. I see how eating space there when I am looking into zip file. Your tmpfs in /tmp is not enough big for 2GB file.
But something strange happened because this tmpfs in /tmp dir is not /tmp in root directory. Maybe someone can explain where it is?
