I can read it mostly but since UBIFS switches mount option to read-only when it encounters an error. After mounting as read-write, if I access /mnt/.wh..wh.plnk (with ls -al /mnt) ubifs gets error and switches to read-only mode.
> Or do you mean your /mnt is UBIFS? If so, It may be a problem of UBIFS. /mnt is UBIFS, but if I try to use /mnt as read-write partition of aufs, I can see kernel oops. (because broken .wh..wh.plnk?) It is true that call back trace shows linux not aufs. But I'm suspicious why there is no .wh..wh.plnk. Does aufs sync after writing .wh..wh.plnk? Is it possible it's been truncated? As far as I know UBIFS never sync unless sync has been issued by command or umount.
