Title: KNC Miners - auto restart script Post by: DPoS on October 14, 2013, 04:29:47 PM A few of us have noticed that .93 will restart cgminer a fair bit when performance dips and enjoyed the better overall avg hashing
Since the other firmwares seem to not care and since there is no crontab installed....I wrote a simple shell script to auto-restart every X seconds Place it in your /bin dir so not to care about paths, and keep a copy in your /config dir since reboots of the miner will overwrite a lot of files I named mine tripminer.sh #!/bin/sh while true do sh /etc/init.d/cgminer.sh restart sleep 9200 done 9200 seconds is about 2 1/2 hours. Change it to whatever you like. if this helps you, a few bits in the tipjar would be nice 1Ki3sFg6bCasB6tkuMW41DCCpGFDgDHVgL Title: Re: KNC Miners - auto restart script Post by: btc_uzr on October 14, 2013, 04:59:46 PM restart only in case of a crash
Code: #!/bin/sh frequent restart as well as restart in case of a crash Code: #!/bin/sh -both untested- Title: Re: KNC Miners - auto restart script Post by: DPoS on October 14, 2013, 05:34:02 PM nice,
I think the best way to mimic .93 would be to monitor your pool's reading of Gh and have it restart after the avg stays below a certain limit for 3 or 5 checks in a row Or perhaps watch cgminer's Gh and HW errors & WU and make up a suitable floor for doing the same I know Kano has a calculation that takes all this and gives an estimate of what 'paid hashing' your miner is really doing I am currently gaining about 40Gh more on avg just by restarting every 2 1/2 hours.. of course if a miner doesn't have issues recovering cores on its own this isn't needed Title: Re: KNC Miners - auto restart script Post by: mininganon on October 15, 2013, 11:20:14 PM BUMP, this got lost in the mix there.
I'll try to play with this a bit and let you know. Title: Re: KNC Miners - auto restart script Post by: mininganon on October 16, 2013, 02:16:28 AM Just restarting CGminer every so often is not bringing it back to life, it quickly loses ghs after 30min and disturbs so many cores it doesn't help. I need an auto reboot mechanism. What I need is a similar script in the init startup to reboot every 2 hours.
If anyone has suggestions Title: Re: KNC Miners - auto restart script Post by: mininganon on October 16, 2013, 03:56:34 AM I ran your 1st script btc_uzr got this
sh cgrestart.sh cgrestart.sh: line 9: syntax error: unexpected "done" (expecting "then") [1]+ Done(127) bash cgrestart.sh Title: Re: KNC Miners - auto restart script Post by: mininganon on October 16, 2013, 11:15:17 AM I have a $5 tip for someone who gives me working script to reboot my jupiter every so many hours. Obviously it has to be run at startup and survive reboot. I have it on .91 with the reboot mod added. Thanks
It would be a bonus if it could detect ghs drop for x seconds then reboot as well.

Thanks It would be a bonus if it could detect ghs drop for x seconds then reboot as well. you'd be better off running the reboot.cgi URL web command from a remote computer on a looped script for that. and since it would be driven from a remote machine, it would be possible to read the value off your pool's page and then do some type of stop limit type trigger for it I'm not much of a web coder but I've seen stuff like this in action. probably not hard for those into that Title: Re: KNC Miners - auto restart script Post by: btc_uzr on October 16, 2013, 09:24:36 PM I ran your 1st script btc_uzr got this sh cgrestart.sh cgrestart.sh: line 9: syntax error: unexpected "done" (expecting "then") [1]+ Done(127) bash cgrestart.sh I assume you ran it on your desktop pc or similar, since the script executes fine on my KnCMiner; tested a min ago On KnC devices there's no bash but sh. /bin/sh -> /bin/busybox and for example Ubuntu links it to dash /bin/sh -> dash Title: Re: KNC Miners - auto restart script Post by: btc_uzr on October 16, 2013, 09:43:57 PM I have a $5 tip for someone who gives me working script to reboot my jupiter every so many hours.
