[solved]df showing wrong info for /var

When I had issues invoking "pacman -Syu", I had a look at my df output and it showed me only 12kb were available. It appeared that I had some huge log files, which I removed (3 x 1,8 GB). The df output didnt change though and I still couldnt run the update, so I invoked pacman -Sc and finally the output changed and I could update my system. Now df still shows me that I have 156 MB of 6.6 GB available whereas "du -hs /var" gives me 1.1 GB, so 5.5 GB should be free and I am confused.

I was wondering why from time to time syslog-ng and rtorrent-mod dont always get along too and seem to cause these large log files, but thats another topic.

When you write to disk, changes aren't committed until buffers are flushed.  This includes deleting.  See man sync for more info.

Depending how you removed these files, they could be sitting in your trash can. Try looking at,

~/.local/share/Trash/files

in both your normal user and root folders and see if they are there - if so then you can remove them from there to free up space.

Well I dont have a trash can, so there is nothing there. Oddly df --sync doesnt change a thing either and I am still confused.
e: Well I restarted syslog-ng and that fixed it. The restart itself failed too at first but oh well..
