Re: ext2 and ext4 fsck errors when using aufs

[Jacob Burkamper]

   Off the top of my head, i can tell you that both lsof and fuser do not show
   any open files in /ro. I have previously checked this.
   I will collect the rest of the the information and get back to you.

     OK, then let's proceed next step.
     - run "lsof" after "rsync"
     Â  find the file which makes your /ro busy.
     - after "remount,rw" run "fgrep -w /ro /proc/mounts"
     Â  confirm that all /ro entries are remounted as RW.
     - split the updating files into several groups. for example,
     Â  rsync updating/etc /ro
     Â  rsync updating/lib /ro
     Â  rsync updating/usr /ro
     Â  Â  Â  Â  :::
     Â  and after for each rsync, try "remount,ro". repeating this step with
     Â  narrowing down the updating file, we can find the file which makes
     Â  your /ro busy.
