Hey guys,Are we allowed to post instructions for gracefully shutting down your RN via SSH on here? From what I can tell my Frontview GUI has stopped responding (6.2.2) and I just want to gracefully shut down so it'll re-start. The buttons on the front and the LCD screen aren't working. I can see the NAS in RAIDar and I can SSH to it/use network shares without any issues. As far as I can tell it is not related to uninstalling an application. Any advice would be helpful.

Hey StephenB, Thanks for the answer. It totally solved the problem and after shutting down it gracefully came back up. I have a question after talking to L2 support. I wasn't home and couldn't do what she asked. She said that the first step would be to unplug my RN104 from power and just do a hard reboot followed by an OS re-install if that didn't clear it up. Isn't doing a hard reboot a 'bad' thing for a RAID? She seemed to casually throw it out like it wasn't a big deal. Also, I mentioned that I had SSH access and she said that only L3 support could give me that command and that the first step would be the unplug process. What do you guys think?Chris

Before you try rebooting or unplugging the power please let me know the output of these commands# systemctl status apache2# systemctl status readynasd# journalctl -a | grep apache2 | tail -n 20# journalctl -a | grep readynasd | tail -n 20# btrfs fi show# btrfs fi df /data# df -hDoing a hard reboot is a bad thing if you have an alternative.

Argh, sorry Mdgm. I just did it before reading this message :/. Can I get you any data after the reboot?Chris

Sure. If you still have the problem that would work.Or if you don't perhaps try sending your logs (see the link in my sig)

Looks like you do have a lot of fragmentation.

What happens when you try to start readynasd?

# systemctl start readynasd

Do any of the fixes mentioned in 6.2.3 beta http://www.readynas.com/forum/viewtopic.php?f=154&t=78866 look relevant?

I missed this message before rebooting it. The Daemon is running. After your comment, I went through and turned on some of the maintenance functions such as defragmentation. It took 2.5 hours last night. How can I tell how much fragmentation it has to make sure it's working?

You should see for Metadata, DUP that less is used than before.
