Sure no problem, If you want to jump on IRC, and join my channel on freenode #ThePeePs, i'll help you as much as you need. If you don't have an IRC client, or dont know hoave to use one, there's a chat page on my p2pool page (see my sig for the link). Sorry to hear about your external HDD. Have you heard of SpinRite? It's saved my bacon a few times. It's $90 US, but it's well worth the price. Should be the first link in a google search.

Cool and no I haven't! I'll look into it. I was able to format mine from my PC - that's all windows wanted to do with it, so I had no other choice as I wanted to save as much as I could from my internal drive! I'm nervous about those corrupted errors I was getting while my files were being copied... but I just want to get the server fully configured before diving back into the installing what I need for the p2pool and mining.

I don't have an IRC client, but I got a lil experience using the web version - can you believe it... IRC cherry only recently popped, lol. I'll look you up

Status update -

I had to start from scratch Sad

I literally couldn't even mount my external dvd drive to boot from cd. I guess when I uninstalled the GUI, something relating to blueman got screwed up and I couldn't install or repair anything without errors. I don't use bluetooth so didn't think there would've been an issue removing/disabling those services but evidently that damn package had its hand in everything. It's a confirmed bug that's still open with no resolution.

To top that off - my external drive, where my backups were stored, was corrupted. This was probably the nemesis that caused this all, because I tried restoring from backup a couple of times. Needless to say, I ended up having to reformat the drive because my PC, MAC, or other linux system couldn't recognize it. So I lost all my data from there. Luckily I was able to copy files back onto it from safe mode, but got several corrupted errors. At this point, I don't know what can be saved from the hard drive.

Anyhoo - I went ahead and installed ubuntu server 14 and a very lightweight GUI (that I don't like). I haven't configured or reinstall anything as of yet, because I want to look in using the VM first.

ThePeePs, I could use your help with this one.

It would depend on what the error was. On my main desktop, i HAVE to run memtest86 from the CD, as it will not load from grub (never took the time to figure out why).

As for your mouning problem; fstab is only used for auto mounting (at system startup) or to manually mount per-defined mounts (that you would use on a reg basis, but not needed to be mounted at boot). If the drive shows up in /dev then it can be mounted manually in one two ways.

If you know what it gets lettered as (ie: sdb, or sdc, etc) then, as root, you can mount it by

Code:

mount /dev/sdb /path/to/mount/point

Or, open the file explorer, and look on the left, and see if you drive is listed there, if so click on it, and it should mount it for you.

I don't have a GUI anymore, so no more clicking on the icon, lol. But it used to show up there up until about a week ago, then it disappeared... I haven't been able to mount it since. I also tried the command you suggested... But I get an error. Something to do about wrong format or something... I'm on the way home but I can tell you exact error when I get there. I messed up mounting last week when I tried to change my backup config via Webmin. For some reason, some changes apply via we min and some don't. I was actually going to remove/purge and reinstall because I I'd try to add a process to start at boot or something, and it refuse to accept it. Although that was the original setting that I stopped.

I'll post more when I get home...

You can use your Ubuntu CD (or USB stick if you used that to install instead) to boot, but NOT re-install and you will have access to all of your files on your drive.

I would suggest this.

After you have all of your files backed up, reinstall, restore your files, get everything the way you want it. If it's a server, do suggest w/o a gui.

Before you fire your p2pool nodes back up, install VirtualBox, and create a VM for your P2Pool nodes (it's how i run mine). on your VM, run the coin daemons, and have their P2P port open to inet for incoming connections, as well as the P2Pool ports. Then on your host machine run the wallets (either daemon or qt) and in the conf file put connect= this way your wallet will remain synced to the network.

This serves two purposes

Your P2Pool node(s), and your personal wallet(s) are separate (less risk of losing coins)
You will be able to better track what is using resources.

Hope this helps.

Um... YES! I didn't know i could use the CD to boot, it's just the original ISO image, nice! I'm having an hell of a time trying to mount my external drive; guess I screwed that up somehow as well because it's not being recognized anymore. I'll try and do this today after work... if this works out - bounty to you!

You can use gparted to look to see if your external drive is seen by the system. (or tail the messages/syslog files and look for err msg's)

Also, iirc the CD should also have an option to boot into memtest86. I would let that run for a least a few complete passes on each test.

Okay, I'll try this too! I looked at the fstab (I think) and it showed up, I just can't seem to mount it so I can transfer my files to it Sad

I'm not a techie so I'm sure I'm doing something wrong.

I did try the memtest option from GRUB but it gave me an error. Will this test let me know whether my initial issue was due to memory?

Also wondering why under heavier (all gpus and nodes) it crashes and now it crashed on its own. Did you swap the HD cable to when you swapped drives and I would still test the memory and make sure bios updated.

Well, it's not crashing on it's own... I messed around with a few config files here and there so that's totally my fault. No, I didn't swap out the HD cable, but I used a different port (is that the same?). The bios is up to date, but I'll also test the memory as well as soon as it's back online. I can't do anything with it at this point until I fixed my big boo-boo! lol

Good lord, what have I done! GUI won't boot now. GRUB menu only allows safe boot... I tried to reinstall the desktop overlay but to no avail. This all started because somehow lightdm decided not to show its ass up at boot.

This is what I get for messing around instead of chilling waiting for someone to assist. Now my site and pool nodes are down Sad

Mining are the least of my worries now. At least I know I'm good with 3 cards, I'll settle for that. Now my focus is bringing my server back up to where it was. Shall we say .03BTC?

Just so you know... I've done this before (guilty - but I'm no techie, so no judgement, lol). Actually I've done worst than this before... but last time, I just threw the hard drive aside and started with another one... this one! And this one has all my files, so I need what's on it.

But I had this thought that I could just grab the other one and reinstalled the LAMP stack on it, giving it a very light light GUI like Awesome or Xfce. Then mount the the one (current) with the messed up config files... but leave all that crap and just snag my personals. This will work but I;m hoping for a better/faster/cleaner solution.

Have you checked bios to make sure their set to the right voltage/speed and timings?

So I changed everything back to auto.... ? The memory has speed of 1333 (i think). the CPU is an 8 core 4.something ghz

I also just tested - I was able to run 3 cards no problem. Turned the other 2 on (guess I should've tried just one) and it crashed. So 3 cards with my nodes are good.

What kind of memory is it? Processor? How many sticks are you running? My system isn't 2 months old and Im waiting on a rma of a stick of memory that lasted a week and 1/2 before the system kept crashing because of it.

Consair. I have 4 2GB sticks running in the system.

If your bios is up to date then try it with one stick of memory and it don't work try it with the other stick. If it works with one stick then most likely you have a bad stick and you can use memtest or any memory tester to test one at a time and be sure. You should be able to run whatever you want with one or two sticks it just generally may not run as well.

I tested the memory when I first put system together but I had an opportunity to play around with my server a lil bit today. I have my 4 p2pool nodes up and now it's only running at 1.57 RAM utilization. I'll try and start mining again to see if I crash. I think I'm supposed to have one gig of RAM per GPU, right? with 8 gigs this should be suffice. If it crashes again, can we rule out memory?

I take that back it doesn't directly share lanes with the memory but it does like require dma (direct memory access). The lanes are just what it uses to transfer the data on new generations being directly linked to the processor. Your pcie lanes are often directly linked to e-sata, Wi-Fi , lan ports, etc. and bios updates sort known issues out (driver conflicts etc). It can be possible for a video card to short out and you lose onboard lan port(s) or onboad wifi etc.

Ah! Gotcha. So I'm able to mine without a problem on this system, and it runs well. It's only when I try to run my coinds and p2pools while mining is the system crashes. That said... is this a memory issue? Apache logs don't even capture why the system failed... it just shuts off abruptly. But I didn't want to go out and buy memory (i have four 2 gb sticks)... because in order to realize benefits, I'd have to go up to 4 GB sticks and I'll have to buy 4 to double the memory I currently have. These rigs are a 10k investment. No doubt a few hundred bucks on memory is nothing compared to what I've already put in - but if I don't have to... I don't want to!
