Just wanted to say thank you to the Hashra guys and everyone else who helped me narrow down the possible issues with my machines.  As it turns out a bad ethernet hub was creating a data collision domain with all the machines.  Once removed all was well.  Thanks again!!

Can anyone successfully running 20 GRDS on a single Pi give me a full list of the hardware they are using from USB hubs to power supply and everything in between so I can keep troubleshooting this.  I have so far not discovered the reason for the random crashing.  Would be very helpful to know what is working for people.

Normal raspbian OS with all the dependencies to build cgminer.
Not sure which cgminer 3.7.2 it is, andareed or girhes. http://i.imgur.com/clzwtn2.jpg?1
USB hubs http://[Suspicious link removed]/Ify5L3
Lutro power plugs
Monoprice USB cables.

Thanks man I appreciate that, what are you using for power to the gridseed units?  What kind of SD Card with the RPi?

i know you said you have re-imaged multiple times, but have you used the same image file each time? Maybe thats the issue. Try re-downloading the file and go from there if you havnt already.

Spot on… Yes please try this out.

Regarding HUBs we suggest to use the most powerful you can get, the 20 port versions we have on our site for the Atlantis is one we get made to order here in Shenzhen… uses 90W power… I am sure there was a stability increase when we started using these.

I'm sure someone is selling these on ebay.

Could you link me to this exact hub by chance?  Thanks!

at the moment I am using a 8Gb KINSTON SD SD4/8GB CLASS4

http://www.scan.co.uk/products/8gb-kingston-sdhc-memory-card-class-4

which has been fine for weeks


the image is the  darkknight version (see above) written with the applePi-Baker then updated

What are you using for USB hubs and for a power supply?  I'd be interested to know all the components of a working system.  Do you run 20 Gridseeds on a single Pi?  Thanks!!

I wish I had purchased this now, but I bought Sandisk class 10 8gb cards.  Hopefully they will work.  Right now the machines are running off of the NOOB cards delivered with the Pi.

I want to clarify when I say the Pi is 'crashing'  I mean that the GUI locks up, mining stops and I get the message from the pictures above when trying to log into the Pi over the web GUI.  For all intents and purposes the Pi looks like it is still running but only a hard reboot will get me back in.  The things stop mining every like 6 hours at this point and I am baffled as to what could cause this.  Some of them also seem to stop mining at the exact same time and I cannot figure out why that would happen either.  They aren't linked to each other in any way.

maybe you have a problem with your electrical supply something that is putting an intermittent high draw on the power or adding noise to the line

Is it possible that the power draw to the Gridseed units changes depending on what coin they are mining?  I am using a multipool stratum (clevermining.com)  If certain faster or slower coins caused the power draw to change I could see this being a possibility.

Thanks AmDD I will try that.  I am also buying some class 10 Sandisk 8gb cards to see if maybe I got a bad batch of NOOBS cards shipped with the Pi's...always a possibility.  Not much more I can try if that doesn't do the trick.

Anyone else having this issue with the Controla software or can I pretty safely say that I am having some type of hardware issue?  What is everyone using for USB hubs for 20 miners?

It's unlikely that hub problems are crashing the pi all they will do is drop the gridseeds that said I am using the Etekcity® 10 Port USB 2.0 Hub Powered External with 3A Power though it may be called something else in your country.
http://www.amazon.co.uk/gp/product/B00ELPSEVW/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1

Raspberry Pi crashes are down to a faulty/damaged SD card image or the pi not getting enough stable power

This sounds like good reasoning.  Is it possible that the cards themselves are faulty?  Or just the image?  I have re-imaged the cards many times so if the image keeps becoming faulty the cause of that would be bad SD cards maybe?  Or perhaps the fact that the Pi is crashing and hard booting, I suppose this might corrupt the SD card.  But that still wouldn't explain why the Pi's are crashing.  And also when I say the Pi's are 'crashing'  all I mean is that they are locking up, the hashra interface GUI is inaccessible and mining has stopped.  They dont actually shut off.

I've had PI crashes because of unstable power. A good way to tell if you're having unstable power is if the red power LED is flickering. TP1 and TP2 on the RPi should measure above 4.75V with the Pi active and hashing away. Best to use a known good power adapter (like a good original phone charger that's at least 1A capable).

Is it possible that the power adapters that came with the Pi are not suitable for stable power delivery?  I do have all my equipment plugged into the same outlet for each rig, maybe I should separate the Pi's to a different outlet.  Anyone recommend a power supply with a micro usb connection thats good quality for the Pi?  Thanks guys.

I wanted to post a picture of the message I am seeing on the GUI when it locks up,  this may point to me having received trashy SD cards or possibly a corrupted image file on the cards.  I am going to use Apple Pi Baker to re image the SD cards to see if this fixes anything tonight.http://s1.postimg.org/9tqfsmr27/Screen_Shot_2014_04_16_at_5_47_20_PM.png

Yes, think this is wise to do. Make you obviously click update firmware once downloaded to make sure you have the latest version running.


Thanks for all the help unfortunately the re imaged Pi did not seem to resolve any issues, still recurring instability across the machines.  Could I have been sent bad SD cards somehow?  Really not sure where to go from here..

I had the same issue after I did the last update. And again the other night. Stayed up all night trying to fix it.
Came across a very useful article and I followed the steps and it worked.  If you have 2 or more SD cards, its probably the image is corrupted on it. Which seems to happen from time to time with the PI.

Use one of your good cards and back up the image on it. "clone" it.  Then use the clone for any cards that might have a problem.  It worked for me.

As I mentioned I re imaged the cards multiple times with no success.

what's the freq?
what pool?

which I think to be pretty decent quality hubs.  The ones I got shipped when I bought the units were trash 6 dollar hubs from china.  Not a single one of them worked properly.  I wasn't even able to boot a pi with 20 units.  Since I bought these hubs everything boots up and runs fine its just a matter of working out the shutdown issue.  Can I work around this problem by maybe entering a large number like 500 for an 'n' value of time between restarts on the GUI?  As I mentioned the issue seems only to occur when the GUI sends the command to restart.  A hard reboot works fine and they come right back up and start hashing.. Also would there be anyway to program the pi to hard reboot the machine every set amount of time?  Thanks for the help!

If you think the restart is causing the hanging, you can set this to 0, which means, it will never restart the mining process. But still, It's strange, It should run fine with 20 miners. I am using a different hub though. What model PI are you using ? the model B?

If model B has the dual USB ports then yes it is model B.  Yes I find this issue very odd as well... The only thing I can figure is that is must be the GUI is some way whether it is corrupt on the SD card or otherwise.  Would be odd for it to be corrupted across all 5 cards however...  Some people recommend daisy chaining the USB hubs together rather than utilizing both ports on the Pi but it doesnt seem to be an issue on startup so I dont see why that would cause a problem on a restart...  Also not that this is related but I notice when I go to manually restart the machines that the GUI has completely locked up and sends me to a nearly blank html page that looks like an empty repository or the like.  This will sometimes occur after a few minutes of mining and the GUI will not be available to me until a fresh hard boot of the Pi...  The machines continue mining through this issue so I never really thought it was a huge problem but perhaps my intermittent ability to access the GUI is related to a corrupted image or a bad kernel?

In fact now that I think on it this inability to access the GUI may be why the machines only seem to fail when they attempt to restart after the programmed 'n' number of hours as the GUI has locked up and does not become an issue until this command is sent...  This seems plausible but I am still totally in the dark as to why the GUI would do such a thing... I guess that it points more toward a corrupted SD card or bad kernel of the Controla software however.

Can anyone assist me on this issue?  It seems to crash at the point that it is set to autorestart, I guess it just forgets about the restart part...  they dont all crash at the same time.  I has one crash after 4 hours then 3 crashed at 8 hours then the last one at 12 hours.  Very odd and I have not sure where to go from here...  any help would be VERY much appreciated.  Thanks.

How many MINI's you have on the Pi?

We suggest 20 in Scrypt.... 10 in Dual mode.

I have 20 units on a single Pi.  They boot up and all run perfectly fine until the shutdown command gets sent from the GUI and they just don't boot back up it would seem.  I'm running them off a 30AMP 360w 12v power brick which I really doubt is an issue as they run flawlessly when they are online... Could the Pi SD card be corrupted?  Keep in mind I have 100 units across 5 Pi's and this is happening on all machines so whatever the issue is it would have to apply to everything not just one or two machines.  And since they dont all seem to crash at the same intervals the issue gets a bit more convoluted.... Hopefully someone can assist.  I really like the Controla interface so I hope that is not the issue.

-Andrew

20 units should be fine with Controla at 850 Clock speed.

What USB hub you using? sounds alike it could be a hardware issue. Really want to use really good quality powerful HUBs if possible, does make a big difference.

I am using these hubs

http://www.amazon.com/Plugable-USB-Port-Power-Adapter/dp/B00483WRZ6/ref=sr_1_3?ie=UTF8&qid=1397679929&sr=8-3&keywords=10+port+usb+hub
