My Impression of Avalon Machine (cooling info updated)

[loshia]

Hello,

How is going with Avalon stability? Is it ok or you need to act when it stop hasshing.
---------------------
6 there is some monitoring logic in cron, but it does NOT prevent the machine to get wonky (jgrazik & me both have experienced, crying~~).
Here is a snippet might be useful.
(default port is 4028. I'm not responsible for any loss if the snippet doesnt work as expected. you should know a little bash scripting)
RESTART_MONITOR="(echo -n 'devs' | nc ${IP} ${PORT} | grep 'MHS 5s=0.0') && (echo -n 'restart' | nc ${IP} ${PORT})"

----------------

As i can understand that this script is not much reliable. Can you clarify why from the following options

1. (echo -n 'devs' | nc ${IP} ${PORT} | grep 'MHS 5s=0.0')  - it is not reliable and even avlon not hashing you are never finding string 'MHS 5s=0.0'
2. echo -n 'restart' | nc ${IP} ${PORT} - Restarting cgminer is not solving the problem
3. restart the machine (soft reboot) from ssh/telnet with reboot command is not slowing the problem
4. Power Off and On (hard reboot) is the only solution?

In general i am interested to know the following:
1. Is there automated way (via script locally) to find out for sure that avalon is not hashing
2. Only power off/on solves the problem or soft reboot from the script will do the job?

Yes there are a LOT of statistics available via the API.
It's simply a case of finding what stats show the problem they are having with the hardware and using that.
(Yes from what was said before 'MHS 5s' did not go down to 0 when the problem occurred)

Thanks Kano i missed that info:)

techwtf any chance of some small guide been provided on what you did to configure it and get it up and running. I know The units has as much as own system and connection and web inter phase any details on setting up checking temps speeds.

Any chance of some videos and guides regarding this?

updated some details about monitoring. it should have no difficulty if you have played with openwrt before. make sure you save and apply the settings.

Never used openwrt before that is why was asking how to or make some videos or instructions to get running ad awaiting arrival of own unit

Hey,It is easy:)
Have you configured scho router via web interface?  
IP/MASK/GW DNS or DHCP client(!!!Shall be avoided static ip is preferable) - as long as utp is connected to WAN
Cgminer has a web backed as far as i can see - you have to enter pool url , user(worker) and password form openwrt web interface

That shall be all

Im curious about the temperature of the room before starting the machine

so its some sort of interphase like a router connect to ip and you connect to it and define settings for it to use and thats it?

23 deg.

techwtf,

Is there a free unpopulated usb port on the internal usb hub?
I wanna install 3G as backup so i am wondering if i shall prepare additional usb hub or built-in one will be just fine?

10X

PS: How about instability issues are they fixed with latest images?

1: yes, 4 total, 3 remaining.
2: you should use another router as upstream.
3: running & capturing debug info, if the problem appear again, related info will be submitted to xiangfu for more investigation. I do hope I can remove the monitoring script above.

Thanks!

I will use same router:)

I will install 3g USb outside the box
3g ppp interface will be up all the time and when internet dies a script will change default route only
There are no hanging issues currently right?

the hanging issue is now under investigating, even other owner have reported fine for 7days+.

That number represents the last time 'valid' work was returned by the device.
Thus e.g. with an Avalon, it should NEVER reach 60s in the past (current time = STATUS/When) so you will know quickly if something has gone wrong.
It's using device difficulty (not share difficulty) i.e. it's before the share is validated as being above required difficulty, but after it is validated as not being a hardware error.
... you may find it useful

There is a cron job monitor the cgminer: (compare the Accepted every 5mins, if there is no Accepted in 5mins. restart the cgminer)
   https://github.com/BitSyncom/cgminer-openwrt-packages/blob/master/cgminer/files/cgminer-monitor

Can you paste the cgminer log.  remove the '-q'. add '-D --verbose > /tmp/cgminer.log' under /etc/init.d/cgminer. and the 'dmsg' output.

You may want update to latest 703n image:

10X xiangfu!

My 8M image with chip is waitng for the unit - with latest Avalon cgminer branch. Just for the record does soft restart of cgminer solves the potential issues or Power off/on is required?

I think it is a strange single? problem worth fixing, but you may never experience if you're lucky ... I mean, you should do enough monitoring, prepare for the worst. most of times power cycle is not required. if the machine needs power cycle, the light on the back of the fan will become red.

Anyway I do have snmp power relay switch so i can plug off/on power when i need to automatically:)

Thank you very much for your response techwtf:)
