Hi, all. I need your help to find out what happened to my hard disk. The problem I've met is according to the used space in my /dev/sda8, there should be 6G left. But there's only 1G now. I can't move a file larger to 1G to that partition. Tried, but failed. I've also run some test and repairs. Unfortunately nothing's changed. Now I show you the results.

It cannot be journal. At least before yesterday sum of used and free sizes always equaled total size, refered to "df". So far as I could recall, the mistake may be that I deleted a directory in that partition when a extraction of files was running unnoticed into the same directory. Anyhow it was deleted afterwards. -- Mit freundlichen Grüßen Zichen Chen
