I see no problem, you can do for example:

# rm /sbin/reboot
# rm /mnt/HD_a2/fun_plug.d/sbin/reboot
# ln -s /usr/sbin/do_reboot /sbin/reboot
# ln -s /usr/sbin/do_reboot /mnt/HD_a2/fun_plug.d/sbin/reboot

This will allow you to cleanly reboot by using the 'reboot' command.
The same will apply for shutdown, but the link should point to '/usr/sbin/do_shutdown'.

Thanks, I have updated the script (version 1.1) with your suggestions

* Problem:

When you install fun_plug in your DNS-323 or CH3SNAS box, it runs most of the programs from the mounted hard disks, so it prevents them from being unmounted cleanly.

You have this problem if your dmesg shows the following line:

Code:

EXT2-fs warning: mounting unchecked fs, running e2fsck is recommended

Hi Pof,

My installation of (minimal) fun_plug does not run any programs from mounted disks after startup, and thus I am able unmount all disks through TELNET.  I still get the EXT2-fs warnings.

Even if fun_plug is not installed, it seems the DNS-323 does not shutdown cleanly.  In this case, cleanboot would be useful even if fun_plug is not installed?

Hi Pof,

I notice that you have provided a patched version of do_reboot.  I cannot seem to find the source in the GPL distribution from D-LINK.  Could I ask where you got the source from, or if you reverse engineered it from scratch.  The script it generates and run seems simple.

I would recommend some changes to the scripts:

1. in pof-clean*. , first run through the stop scripts and then kill the daemons that are still running with kill -9. Maybe you could extent that list also a bit (upnp, rsyncd, unfsd)
2. make /mnt/HD_a2/fun_plug.d changeable in a central place. i have installed it in /mnt/usbstick

uploaded version 1.3, which includes oxygen's suggestions

@knireis: make sure you have internet connection available (gateway & dns server) set in your DNS323 configuration. Otherwise you can just download the .tgz and place it in your storage through the network instead of using wget.

I have released cleanboot 2.0 (see first post) which includes the following changes:

It no longer depends on the patched do_reboot binary which is not available in dlink or conceptronic GPL sources, I disassembled the do_reboot using radare and found it's pretty simple to implement the same functionality in C. So I rewrote it and put all its functionality in a shell script (/sbin/cleanbot.sh) instead of a binary program, so it should be easily customizable for advanced users.

For those interested in seeing the source it's here:

Instructions to upgrade from 1.x to 2.0 are also in the first post

Hi - I've tried to use version 2 for fp 0.4 but I'm not sure that it's working.

After following the install instructions I telneted to my device and ran "reboot". The telnet session is killed but not much happens in the way of an actual reboot happening. After leaving it for a few minutes I can no longer telnet until I restart via the web UI.

funplug.log shows (below) that the script is starting

"* Running /mnt/HD_a2/fun_plug.d/start/cleanboot.sh start ...
Setting up cleanboot... "

Any idea what I might have got wrong?

I think the only thing I'm running that is not a start script is mediatomb so I'll have a look at that.

Cheers

mmmh... weird, what you've done seems fine.

Is the 'shutdown' command working?
Which firmware version do you have?

No, shutdown doesn't work either.
I'm using he latest stock firmware I could find - 1.04
As I do not see, to have much luck with it, what's the best way to remove the script?
RAP

To remove script you only have to delete cleanboot.sh from your ${FUNPLUGDIR}/start, and also remove ${FUNPLUGDIR}/share/cleanboot directory... restart your NAS and that's all...
