(excuse me for my poor English)
During copying I filled up the entire disk space. When I break copy process system remove unfinished file, but device still shows 99% used (all files on disk occupy only 50% of the place). I rebooted system - nothing. I want to use fsck command, but can't umont device (under CLI and web controll panel; problem with referenced?).
What can I do now? Please, help.
