Shutdown process can't finish : what to do ?

[icy]

Hi all,
Ready Nas Ultra 4 using os 6.1.9

2 days ago; i've initiate a shutdown on the nas, using the front panel button. But the nas want not to shutdown...

- The nas is perfectly available(read/write) with samba.

- Accessing the web interface, i receive a "Device is offline" ... indeed, the nas is not present in the Device section.

- The nas osd blink with a "shutdown ..." message. If I press the button again, nothing changes...

- I can ssh as root! But with a "ps -ef|grep shutdown", no process appear... My linux knowledge are limited...
- a shutdown -c , give nothing.

I guess I can't simply (and safely) unplug the ac adapter... so what to do?

Thx for the help....

Try this command:

rn_shutdown now

You can force a shutdown by pushing the power button for 5 seconds.

Sounds like a service or app must be preventing it from shutting down somehow.

What services are you running and what apps,do you have installed?

Thanks for all your answers 🙂

I am not sure that the 2 methods are the same in terms of the risk of "bricking". I always thought the long press was reasonably safe, but unexpected power loss is more problematic?

What about

# systemctl

[icy]

Today, again I can't reboot...
All previous command won't work.

But today, the samba process (smbd) take 100% of 1 core since a while :

Broadcast message from root@ReadyNas (Sun, 14 Dec 2014 15:22:49 +0100):
 3984 root      20   0  246m 2380  976 R 100.1  0.2  10314:22 smbd
13287 root      20   0 28484 1704 1176 R   1.0  0.2   0:00.48 top

I tried to stop it, kill it nicely and hardly ... it won't be killed...

I've tried :

but

root@ReadyNas:/data/Videos# systemctl
Failed to get D-Bus connection: Failed to authenticate in time.

So once again, i did a hard reset 😐
