Topic: [OS] nvOC easy-to-use Linux Nvidia Mining - page 408. (Read 418251 times)

That is what I thought; just wanted to make sure I understood what you where suggesting.  I didn't know I had to change ownership with chown; I have never been a *nix system administrator.   I have some linux and unix experience (about 9 years); but most of it was very specialized, and generally limited to networking.

I will add implementing your suggested changes and testing them out to the list of:

testing Asus - PRIME Z270-A mobo

improving amdOC beta

lan management monitor / push / update app

dynamically editing xorg.conf automatically

modify / test expectless version of oneBash

potentially if members want ( re-add ssd support )

 

I know that expect is not meant to be used within bash, and there are much cleaner ways to handle privilege escalation.  I want to avoid having oneBash call other scripts, keeping as much as possible within one bash script (oneBash).  It would probably be easier to make oneBash suid; by this do you mean:

sudo chmod 4750 '/media/m1/1263-A96E/oneBash'

or

sudo chmod u+s '/media/m1/1263-A96E/oneBash'

?

I am always open to suggestions for improvements.  I would also never claim to know everything about linux; which is good: because its fun to learn.

No criticism directed - you've done something VERY useful to the community. The fact you did so with little Unix experience is that more impressive! I'm just trying to help.

Both of those commands do the same thing. Here's what you'd have to do:

1. sudo chown root /media/m1/1263-A96E/oneBash
2. sudo chmod u+s /media/m1/1263-A96E/oneBash
3. sudo chmod o+x /media/m1/1263-A96E/oneBash

Now onebash is owned by root and executes with all of it's privs, and anyone on the system can execute the script. After doing that, you should be able to just delete the expect code that provides the password to elevate privs. The down side of this is that the miners now all run as root.  To take care of that, chmod u+s to each mining program and make sure it is owned by the user m1 with chown m1 . Now, each of the miner programs should drop privs when they execute.

This approach allows you to keep one big script -

You should definitely confirm all of this. I'm in management now, and I'm not on the keyboard as much

There are several ways to solve this problem, I have not solved it intentionally.  I have asked members who have asked me about ssd's like citronick if they want me to re-add ssd support in another version; and I will do so if that is what members want.  

I'm interested on everyone's thoughts on my reasoning:

I got an Asus - PRIME Z270-A yesterday, but I haven't had time to test it yet.  I will test it tonight and let you know.


In most cases you can use the newest image I have made with any mobo (whichever is listed last in the OP); and then follow these steps to edit the xorg.conf file:


I will automate this process in a later version by checking then conditionally performing this task.

For the benefit of others using a SSD, the windows partition is not automatically mounted. It is /dev/sda1 and it's type is MSDOS. You can mount it with the followng command: mount -t msdos /dev/sda1 /media/m1/1263-A96E

To have it automount at boot time, you'll have to edit the /etc/fstab file.  The easier option is just use dos2unix to remove the Windows' linefeeds from the file, and move it to a proper Unix partition. That's what I've done.

@fullzero DM me - there's no reason to be using expect here. It looks like expect is used just to handle privilege escalation for commands. You can easily just make the script suid, or call out smaller scripts that need the extra privs. I'll try and update the script when I can - the coming week is a bit crazy though.

Thanks for your work.
Would the ASUS Z270-F GAMING image work for Asus - PRIME Z270-A?
Or is it possible to have a walkthrough on how to build an image?
I haven't received them yet, can test next week.

EXCELLENT! Hopefully Gigabyte will release an updated bios that fixes that issue. I'll shoot then an email to see what they have to say about it. Glad to hear it's not just me though.

Mine is the gaming 3 and I'm using a G4400.

Thanks again for all the work, loving it. Now to see what I can push these cards to.

I will add screen and openssh-server in the next version.

If you installed on an ssd then you will need to interact with the other partition before the system will be able to find oneBash. 

see: https://bitcointalksearch.org/topic/m.19212139

oneBash is located:

Glad you got it working well.   

I didn't need to set gen 1 on my GA-B250M rig.  Maybe it is specific with these cards.  Is your mobo the gaming 3 version?  What CPU did you use?

#1 different pools have different syntax; knowing this is the case with ethermine.org is helpful.

#2 this usually occurs after the disk had an improper shutdown; to check for orphaned inodes and other possible disk errors.  If you have been forcing shutdowns this is expected, if you have not then I would get another usb key.



This is something specific with this motherboard.  I have seen similar oddities with other motherboards in the past.  I sometimes need to hit ctrl + alt + del when powering on this mobo before the bios will post.

Also quick question since you have obviously used this MB before. GA-B250M

Have you ever had trouble with it booting? When I do an initial power up I have to hit ctrl-alt-del to reboot it to get the gigabyte splash screen to show up. After that it boots fine. And it reboots fine if I restart from the OS. When i have to hit ctrl-alt-del i can see a cursor underline flashing on the screen in the upper right quadrant??

I have never experienced anything like this before.

Figured out my issue. I had to set GEN 1 in the bios for my setup to work right. Now TDP is around 115-118w for all 4 cards in Nvidia-SMI and usuage is above 95% for all cards. I appreciate your help.
Getting just under 1200 H/s on my pool with 505 watts at the wall! Pretty happy with that.


Two issues I am having, one I solved just wanted to let you know what I ran into.

#1 - I tried running ETH and kept getting it error. It was rejecting my shares. It took me a minute but I figured it out. I was trying to use ethermine.org and it was rejecting me because of the address/worker name.

On line 483

ETHADDR="$ETH_ADDRESS/$ETH_WORKER"

ethermine.org wants this input as ETHADDR="$ETH_ADDRESS.$ETH_WORKER"
The . separating them rather than the /

I am not sure if this is the case for all ETH as thats the first time I have mined for it. Just a heads up, it worked great after I made that change.


#2 - I am using the 15.5 GB ADATA 3.0 drive that you said would be ok. Sometimes it wont boot, it goes to the boot loader and shows a purple screen and never loads. Sometimes I get a black screen with
/dev/sda2:recovering journal
/dev/sda2: clean, 314012/901120 files, 2478157/3584000 blocks.
If i let it sit there it takes several minutes to finally boot up but seems to work ok after that. Sometimes it boots fine. Should I try a different Drive? Or is this another issue.

So I was finally able to get nvOC going. A few hints for those that use Macs.

1. unzip will error out on the zip file.
2. tar will extract the file but it will be corrupt.

I just unzipped on a PC, and burned there.

As a side note, the images do work on 30GB SSD's as well.

A couple of asks: please add openssh-server, and screen. The addition of both of those allows us old command line guys to still use it.

Finally - where is onebash on the file system? A find from '/' with wild cards couldn't find it.

Right now it's all manual, either by fully reimaging a USB, or for changes that don't require a new client or system change, oneBash can be replaced with an updated version ( I update the newest oneBash link on the OP whenever I make a new version) all nvOC images have a bookmark to the OP in Firefox so swapping oneBash changes from a newer version can be done on a rig itself. 

I will implement a patching system, within a monitor / push app later on.  Generally the idea is an app that communicates with each rig in a local network, getting mining stats from each rig or pushing changes to rigs.

I have had more requests for an AMD version; so I will improve the beta AMD before making the app.

I have some of those cards, I will mess around with them tonight and see if I can get their powerstate to change. 

With your risers, I would try powering two direct with molex (each from its own cable) and the other two with a sata to molex adapter (each from its own cable) so that each riser has its own cable. 

Not sure if this has been asked but how does this os support updating mining software?

I did that command and it says assigned 0.  But nvidia-smi shows P2 still.

These are EVGA 1060 sc 3gb.
I am using 1x-16x adapters v006 blue, USB from deepinthemines.
I am powering then directly with molex from my PSU (no adapters) and I only have two risers per modular molrx cable from my PSU.

Unless the card is locked; you should be able to force p0 by entering this command in the guake terminal:

sudo nvidia-settings -a [gpu:0]/GPUPowerMizerMode=0

and entering the password:

miner1

when promped

note this part is card specific: [gpu:0] for the first card, [gpu:1] for the second ect.

If that doesn't work you may be able to set p0 indirectly by setting a powerlimit of 75 (but this will lower your hashrate to around 265 sol/s per card).

This usually isn't an issue with pascal cards, but what kind of risers are you using?  How are you powering them?

Ok I was able to test some on my 1060 system today.

I seem to get different results each time I restart leading to away from a potential hardware issue??

This restart has been my best and it was a restart from the OS using the restart under the gear icon. The others have been shutdowns and startup from the off position.

All cards are choosing solver 0.

It seems to be one card with lower power draw and and gpu usage with the nvidia-smi command. Also all cards are getting fans set properly and it shows that the overclocks are applied (any way to check from guake?) All cards are running in P2? Is there a way to force p0 on this? I know my other 1060 in win 8 won't apply the memory properly in P2 and I can't force p0 like I did on my Maxwell cards.

Performance is ok. Not as good as my stand alone 1060 I have running (same card). It gets 305 sol/s at 135/400 mem

I'm getting 271,286,288,305 now on these with 135/300


I appreciate any info you can give me on adjustments to make or things to try.

I missed this part before.  Yes, nvOC should recognize your USB wifi adapter.

This mobo should have similar requirements to the z170 gaming 5; but I can't say for sure:

Other members have reported that the Version 1.7 bios is the one to use for this mobo:

Download BIOS Version 1.7: https://us.msi.com/Motherboard/support/Z170A-GAMING-PRO-CARBON.html#down-bios

unzip, copy to usb key, attach to rig, use the m-flash to flash the 1.7 bios

then ensure you set Above 4G decoding to enabled

Also you might need to use a skylake CPU: G4400

If you try this let me know how it goes.
