raiditup Posted November 11, 2015 Share Posted November 11, 2015 I've been trying to reboot my Unraid 6 server via command line while logged in through SSH. I tried using "powerdown -r" but the -r flag seems to be ignored and all it does is power off the server completely. Is there a different command I should be using? I initially tried shutdown -r now but that causes an unclean shutdown and it does a parity check when it starts back up. Any help would be mucho appreciated and sorry if the answer has already been posted somewhere else. Link to comment
dlandon Posted November 11, 2015 Share Posted November 11, 2015 Do you have the powerdown plugin installed? Link to comment
raiditup Posted November 11, 2015 Author Share Posted November 11, 2015 No I dont. Is that required for the powerdown to work correctly? Link to comment
raiditup Posted November 11, 2015 Author Share Posted November 11, 2015 I've tried it multiple times. powerdown -r still just cleanly shuts down the server but doesn't initiate a reboot. I can reboot the server via the GUI by taking the Array offline and then initiating a reboot. Link to comment
dlandon Posted November 11, 2015 Share Posted November 11, 2015 I mean type "reboot" at the cli. That is the command to reboot. Link to comment
raiditup Posted November 11, 2015 Author Share Posted November 11, 2015 LOL. I tried "reboot" and it looks like it did an unclean shutdown. It rebooted but now my server is running a Parity Check. I think it did the same thing as a "shutdown -r now". Link to comment

I think it did the same thing as a "shutdown -r now". If you install the Powerdown plugin that it does a more robust shutdown than the built-in powerdown command. I expect that at some point the built-in version will be upgraded to make the plugin superfluous but at the moment that is not the case. Link to comment

It calls emhttp to do an shutdown that is the same as the shutdown from the webgui. It should be clean. After installing the powerdown plugin, do a cli reboot and post the log that is saved at /flash/logs so we can see what is causing the unclean shutdown. Link to comment
stealth82 Posted January 16, 2016 Share Posted January 16, 2016 I did issue a reboot command and happened to me just now: unRAID detected an unclean shutdown... Link to comment

stealth82 Posted January 16, 2016 Share Posted January 16, 2016 I don't have any /flash(boot?)/logs folder Link to comment

Are you sure you had the Powerdown plugin installed? If not then the reboot command will bypass the unRAID tidy shutdown. Instead of using reboot maybe you should try: powerdown -r as that would return an error if you have not got the plugin installed. Link to comment
stealth82 Posted January 16, 2016 Share Posted January 16, 2016 I don't have the plugin. Is it the plugin that copies the log to the flash? How is it possibile that, in order to perform the most basic of the commands in the universe of Linux, you need an additional plugin to make it work? Link to comment

How is it possibile that, in order to perform the most basic of the commands in the universe of Linux, you need an additional plugin to make it work? The shutdown of an unraid array is not the most basic of Linux commands. All processes on the array need to be stopped before the array can be shutdown and disks unmounted. The most likely culprit is a plugin that is not shutting down properly. The powerdown plugin is not a requirement, but it provides some extra features like keeping an archive of logs. To troubleshoot the shutdown problem install this plugin http://lime-technology.com/forum/index.php?topic=42881.0, click on the Help and follow the instructions near the bottom of the page. This will show you which process is holding up the shutdown. Link to comment

Yes - this is part of the additional functionality added via the plugin. I would strongly recommend installing the Powerdown plugin How is it possibile that, in order to perform the most basic of the commands in the universe of Linux, you need an additional plugin to make it work? The idea is that you should not be working at the command line, but via the GUI and then this becomes a moot point. Having said that I expect at some time (hopefully soon) the enhanced functionality provided by the Powerdown plugin will be incorporated into the base unRAID system so that even working at the CLI level it functions as expected. Possibly the most important enhancement the plugin provides is that it normally achieves a tidy shutdown even when the web GUI is unresponsive as this is one case where you are likely to be working at the CLI level.
