I came home this evening and went to start a video from our Dune media player.  The media player locked up and would not start so I rebooted the media player and tried again, same issue.

 

Next, I went to my PC and tried to check the server status.  Neither the main unRaid screen nor unMenu would respond.  I guess I should have tried to telnet in, but it didn't occur to me at the time. 

 

1st Question, For future reference, can someone tell me the command to manually shut down the server if I run into this again??

 

Anyway, so I did the thing that you really never want to do and manually powered it down (yes hold the button).  I was confident there was no disk activity at the time.  No other sources could have been reading / writing and the parity drive is connected to the MB so with no disk activity light nothing could be in the write or parity process.

 

After reboot, I could see on a connected monitor it was to the login point so everything should have been fuctional.  However at first I still could not get the unRaid main screen to come up.  After much delay unMenu did come up but out of the 12 drives in the array, only the single SSD was showing up as having any data on it.  Note the SSD s connected to a seperate SATA card.  The other drives, none of which showed anything, are connected straight to the MB or do my Supermicro AOC-SASLP-MV8 card.  Also no network shares would respond via Windows explorer.

 

I gave it another 5 or more minutes, finally everything started acting normal, and a parity check started automatically.  I'm guessing the parity check is because of the bad shutdown.  I stopped it and rebooted properly.  This time everything came up correctly.  I will run the parity check tonight just to be safe, but think its fine.

 

I did dump the syslog from by strange restart where nothing wanted to start right and have uploaded it here. 

 

2nd Question, Can anyone see a reason why this would have occurred? 

 

Thanks

Not sure why it happened, but assuming you have UnMenu's Clean Powerdown module installed, you should only have pressed the power button momentarily -- NOT held it in to force an immediate power-off.    A momentary press will initiate a proper powerdown ... just wait a minute or so and the system should shut down.

 

If for some reason that's also hung, THEN you can do the "hold the button" bit.

 

 

... Just noticed your list and you do indeed have the Clean Powerdown installed, so that's what you should have done.    You could have also simply unplugged the UPS (simulating a power failure); and the APC UPS package would have initiated the power down after whatever interval you have set for that (I believe it defaults to 5 minutes if you haven't changed it).

I tried the quick click of the power button, but it didn't work, and did wait a few minutes with no response.  I didn't think about the UPS but I think it's set for shutdown when it gets to 15 or 20% battery, and it's a smart UPS 1500 so it will run for 20 or 30 minutes unless it's running a parity check.  Given it wasn't responding to anything else it's doubtful that would have worked either (right?).

 

Thanks for having a look.

You're likely correct => the UPS package uses the same Clean Powerdown package that is tied to the power switch ... so if a momentary press of the power switch didn't work; the UPS probably wouldn't have worked either.

parity check ran fine.  All is functional again.

 

thanks.
