Title: Avalon controller restarted, how can I find root cause in the logs Post by: ogombii on February 28, 2018, 12:54:51 PM Help please.
I know my cluster of 741s restarted 2 hours ago, I’m guessing the controller restarted, where can I find the event and trace the root cause the logs?

Sometimes reboots just happen, you lose like 1 minute of mining time on a reboot, not really worth expending a bunch of effort on figuring out what happened.

I think mine had done it 2 times in the last 3 months. Everytime it restarts and goes about it's business. I got worried the first time because I got a pool notification, and by the time I got to my setup everything was fine. So I stopped worrying about it.

Make sure you are using a minimum of 2 amps and make sure it is true power and not a chinese knockoff 2 amp that is normally only around 1.5

BUT I would say it's only 95% of the time. SD cards go bad a lot too. I have several pieces of equipment run by RPi, not just miners. 1st thing to check is the power. 2nd thing to do is burn a new SD card. That is if it's a "name" brand SD card, the cheap no name ones are truly bad. But one random reboot here and there is not a big deal. -Dave Title: Re: Avalon controller restarted, how can I find root cause in the logs Post by: ogombii on February 28, 2018, 07:35:47 PM I really appreciate the input, so thinking ahead, it’s best for to have a spare controller, spare SD card with pool settings and spare RPi wall wart ready to swap out; if needed.
Thanks to all who gave insight into cause and how to react to any future event. Happy Mining. |
