last days one of my Pi2 crashed over night. At morning i realized the Pi is down (no response on network, plugged to monitor and keyboard did not give any response) I plug out/in the power supply to restart the Pi. The red and green LED are on bright and steady.

Okay first thought was a corrupt SD card, i put the card in another Pi2 and it booted without any issue. Back in the faulty Pi again both LEDs are on. I tried another SD card with a fresh downloaded Raspbian image but no changes - no boot. Changed the power supply no changes... seems to be dead.

I was quite busy and couldn't investigate more so left the Pi without Power for 2 Days. Today i decided to throw it in the trash but before I plugged again the power and it booted. I rebooted serval times and the Pi seem not to have an issue. Now it runs since 7hrs in normal condition.

  • What could be the cause of the fault?
  • I backuped the SD after crash, in which logs i could find details for the crash?
  • is the Pi still trustworthy for 24/7 or would it be better to replace it?

Alive.

It was probably the polyfuse. Your shady power supply might have tripped it, unless it was from a reputable source.

Other than that, an accessory might have pulled too much power from the Pi, blowing the polyfuse.

For past logs, you can check out /var/log/kern.log if you're on Raspbian.

Yes, it may still be trustworthy. I would't worry about it. Just check your accessories if they draw too much power.

If, for example, you have 4 external HDDs attached, you may want to get a powered hub.
