After upgrading to 7.0.1 earlier this morning, everything seemed to be ok.

 

But whilst reading the newspaper (electronically, stored on UNRAID) the pdf reader suddenly stopped and after some mins of waiting told me that the share was not available anymore ?!?!?

 

It turned out that whole unraid was "not available anymore".

I had to go down to the garage to turn the machine back on.

 

Checking the previous syslog, I found:

 

Feb 26 10:54:22 F elogind-daemon[2104]: Power key pressed short.
Feb 26 10:54:22 F elogind-daemon[2104]: Powering off...
Feb 26 10:54:22 F init: Switching to runlevel: 0

 

Whatever this daemon things, there was nobody in the garage and nobody pressed any button!

(the rest showed a clean shutdown, nothing bad happened)

 

So what is this and how can I prevent it to happen again?

(The garage is quite far away, its cold and raining... I don't want to run there every 2nd hour.)

Could be a button going bad (I've had it happen more than once), or a critter ran across the terminals

Yeah I know, but both are unlikely... The machine is in a 19" rack and the "button" is sealed and so small, that my fingers are too big to hit it, even if I wanted it. And even if you find it, the power to press it is beyond any critter... (ok, a tiger or lion maybe strong enough, but they wont be able to hit it with there claws. Also, there are very few (to no) wild animals running around in my (closed) garage...

Maybe a mouse, but as I said, not strong enough)

 

I will keep an open eye at it...

Doesn't have to be an animal, a bug can short it. I had a media center machine in a closet that kept turning itself off randomly during the night, and Windows reported a power button push as the source of the shutdown. Turns out the button was sticking juuuuuust enough to let the machine run but with enough thermal expansion/vibration/farts it would make contact and shut down

yeah I know, thats why I have set the title to "strange things".

Maybe there is a way to tell this daemon that "3 presses in a row" are needed to start shutdown. A single short press is dangerous.

You can change the behavior, just google 'unraid power button behavior'

ok, I have disabled the button now and will monitor the syslog if it ever happens again....

(The proposed "switch it with reset button" is not suitable here. Both are side by side and glued together (dunno how to describe it in englisch, all buttons and LEDs are together sealed in a plastic stripe and glued onto the front of the cabinet.))

Typically you would unplug and switch the wires to the headers on the motherboard, so the reset button is wired to the power header, and leave the power button wires disconnected.
