Title: Empty tmpfs mount reported as full Status in linux package in Ubuntu: Won't Fix Bug description: After using a tmpfs mount for a while it starts reporting that it is almost full and become unusable. $ mount ; df ; sudo ls -alR /tmp/test/ <snip> none on /tmp/test type tmpfs (rw,uid=1000,gid=1000) none on /home/ken/.wine type aufs (rw,br:/tmp/test:/home/ken/.wine.dotnet20) Filesystem Size Used Avail Use% Mounted on <snip> none 1003M 881M 122M 88% /tmp/test none 1003M 881M 122M 88% /home/ken/.wine /tmp/test/: total 12 drwxrwxrwt 4 ken ken 100 Aug 6 20:35 . drwxrwxrwt 10 root root 12288 Aug 6 20:38 .. -r--r--r-- 1 root root 0 Aug 6 19:08 .wh..wh.aufs drwx------ 2 root root 40 Aug 6 19:08 .wh..wh.orph drwx------ 2 root root 40 Aug 6 19:08 .wh..wh.plnk /tmp/test/.wh..wh.orph: total 0 drwx------ 2 root root 40 Aug 6 19:08 . drwxrwxrwt 4 ken ken 100 Aug 6 20:35 .. /tmp/test/.wh..wh.plnk: total 0 drwx------ 2 root root 40 Aug 6 19:08 . drwxrwxrwt 4 ken ken 100 Aug 6 20:35 .. As you should be able to see the tmpfs mount on /tmp/test claims to be using ~900 MB but it's really only using a few bytes. It works perfectly for a while but then does this. I have been using the mount with aufs and the copy-on-write files are stored here. Since starting this report the "used" amount has dropped around 20 MB but there's no reason for this. There is no longer anything running that would use this directory. Nothing seems relevant in dmesg or the syslog. I don't know how to debug further. I will check the upstream kernel, but this is likely to cause other problems and will probably be difficult to recreate. I will report back once I know.
