Hi I am using aufs for a project, and have some issue with reported disk space usage. I use aufs between a tmpfs set at 50MB, and a directory on an iscsi server, with the mount point also being another directory on the iscsi server. We have an application which writes log files into the aufs mount point ( which are written into the tmpfs part of the aufs ), and then I have a seperate application which copies down the logfiles from the tmpfs into the bottom layer of the aufs, and then deletes the copy from the tmpfs. My problem is that the aufs mount seems to do some cacheing so that over time the tmpfs fills up. Even when I stop the application and remove all files from the tmpfs, it still shows as having disk space used, until I unmount and remount the aufs. It takes a long time to fill up, perhaps 3-4 days of operation, so the amount of data is small.
My mount options are mount -t aufs -o dirs=/vid/ram/00:/vid/00/logs_rw udba=reval /vid/00/logs Can you tell me why the disk space shows as being used, and if there is something I can do to ensure these caches are cleared ?
