 About an hour ago the NYA, pass-thru, and de nodes went down for several minutes. When they came back up - my 4 Avalons (3x 721, 1x 741 on 1 controller) at work have now lost a total of 7-8THs! Rebooted several times, restarted cgminer several times - no go. Before the outage I was running 27-28THs with them, now down to 20-21THs. The 741 at my GF's house is also now running slow - down to 5.6THs. I see that Canaan has also massively dropped from a couple PHs down to ~500THs. What has changed that the Avalons don't like?  ?? All my Bitmain miners came right back up to normal speeds.

I have also run into this problem from time to time with my 721 and I've been able to fix it with reboot in the web GUI Avalon Devices Status. |

All my Bitmain miners came right back up to normal speeds. The disconnect was NYA - 17:56:50 UTC - it reconnected only a few seconds later 17:56:55 - so miners should have just failed over and back again. Also - it's a node, not a passthru - minor difference It had no effect on Canaan, they lowered their hash rate over half an hour, from around 17:15 to 17:45, before that, and don't use NYA. If HagssFIN's suggestion doesn't help, check your PSU to see if that was the cause of the problem? I've managed to kill my PSUs on my 721 that's why it doesn't mine at the moment - the 741 I have much better PSUs on it. Otherwise contact Canaan support. |

Rebooting in Avalon Device Status with subsequent restart of cgminer always brings it back to 6.x |

There was a second reconnect on NYA at 21:49:31 UTC
While the server provider had stated there were issues in New Jersey a couple of hours after the previous very short network dropout, it hadn't affected the hash rate.
However, the node code crashed at 21:49 and automatically restarted as per normal if that happens, so everyone on NYA will have again reconnected at 21:49:31

Interesting. I have the NYA node as pool 0, the pass-thru as pool 1, and the DE node as pool 2 on both Avalon controllers (at work and GF house). All 3 dropped out on both locations. I just restarted cgminer on hers (a 741) and it's back to full speed. Interestingly, AFAIK only one of the Bitmains complained (beeping), an underclocked s7 in my office. The ones at work: Tried cgminer restart. the 3x 721's on the controller are fine, the 741 barely over 6.1THs. GUI reboot of the 741. Same. Hard boot of the the controller and all miners on it. Same. All PSU's are APW-1600's and have always been trouble free. Got a hunch the 721 and 741's don't play well together on same controller and have another Raspi hanging around so will try the 741 on it's own control. |

Ditto on the 721 reboot thingy...happens here occasionally. Considering the issues I had with the S7s, that's nothing.
|
To infinity and beyond...on two 741s and one of only 3...nope, make that 4...full nodes in Hawaii...on <30A. (I have other gear on the Hoth ice planet)

Even more curious. Just checked the detailed Awesome Miner log for my 2x s9's and 2x R4's at home and only 1 R4 shows a blip for the issue. I'll have to check the log at work to see if it's the same. Again, only 1 s7 at work lost connection long enough to start beeping so problem is restricted to the controllers (both are Avalon's) and in my case at work, possibly running 721 and 741's on same Pi. Different chains but 1 Pi.
EDIT: 8:50p EST, looks like the 741 at work has finally gotten up to full speed. Considering how long it took using 721's and 741's together vs each type on its own controller bet thass the reason. TBC in the Avalon thread.

Well March stats are complete - it's now April UTC After a slow start and a pretty low luck run in the middle, the pool average payout ended up 97.81% - thanks to the high transaction fees we gathered. Better than 'certain' top pools It's been a good rise in hash rate this month, getting back lost ground from before, and there should be a very good rise coming in this month also. Mine on |

I'll be upgrading the SG and JP mining nodes in about 17 and 17 1/2 hours at:
SG 1-Apr 23:00 UTC
JP 1-Apr 23:30 UTC
The web site shows this now also.
The expected outage is less than 5 minutes for each node.
I've separated the update by 30mins in case anyone is mining to them both as primary and backup - they won't need to change anything.
If you only mine to one Kano node and it's one of those two nodes, make sure you also have a secondary backup Kano node.
No other mining will be affected - only SG and JP.

DE node just dropped off the air for about 2 minutes there (at 12:01 UTC) but is back on again.
Anyone mining on the DE node will have failed over and back again.
All DE miners have reconnected, and about 70% have failed back already also (that can take up to 5 minutes)
