I have Debian 7.6 installed on an OpenVZ VPS with 10G hard drive space, but for some reason it claims 100% is used when I'm clearly not using that much. I ran df -h to find out the following:$ df -hFilesystem      Size  Used Avail Use% Mounted on/dev/simfs       10G  5.3G     0 100% /tmpfs            16G  1.1M   16G   1% /runtmpfs            16G     0   16G   0% /run/locktmpfs            16G     0   16G   0% /run/shmI then deleted some old files to see if it changed anything and used df -h again only to find out that usage is still 100%.$ df -hFilesystem      Size  Used Avail Use% Mounted on/dev/simfs       10G  3.9G     0 100% /tmpfs            16G  1.1M   16G   1% /runtmpfs            16G     0   16G   0% /run/locktmpfs            16G     0   16G   0% /run/shmThe control panel for the VPS says following:I can delete files but I cannot write anything new. What's up with that? Is another client possibly using up my space on the hard disk causing my operating system to be unable to access that space?I should also mention that I did a full apt-get update followed by apt-get upgrade last night. Could that have something to do with it?
