It means that aufs thinks that there was no "Season 1" somewhere under
/mnt/disk3 in the beginning, but, then found it unexpectedly and
suddenly. Usually it should not happen unless you created "Season 1"
bypassing aufs. I don't understand what is happening.
I need more info such like this.

----------------------------------------
When you have any problems or strange behaviour in aufs, please let me
know with:
- /proc/mounts (instead of the output of mount(8))
- /sys/module/aufs/*
- /sys/fs/aufs/* (if you have them)
- /debug/aufs/* (if you have them)
- linux kernel version
if your kernel is not plain, for example modified by distributor,
the url where i can download its source is necessary too.
- aufs version which was printed at loading the module or booting the
system, instead of the date you downloaded.
- configuration (define/undefine CONFIG_AUFS_xxx)
- kernel configuration or /proc/config.gz (if you have it)
- behaviour which you think to be incorrect
- actual operation, reproducible one is better
- mailto: aufs-users at lists.sourceforge.net
