Hi Tomas Thanks for your reply, I had tried that before, and it doesn't seem to make any difference. The disk space is only cleared once I actually unmount the aufs mount. Our application writes a lot of logs into the mount ( up to 500 times a second ! ), so I can't really unmount and remount the drive without causing problems.
