Greetings, My root filesystem suddenly shows 100% usage even though there's almost nothing there...df shows its 100% but I am sure it's not...I tried to move and even delete, uninstall some files, applications to check if the usage somehow goes down...it doesn't..du doesn't show anything extraordinary...is there something I can try to find out what's happening and or to pinpoint the culprit? Hoping for some sort of advice. Thank you.
