Arughhhh Farm Crashed!!!

[Ducker]

Had the best day ever yet day before yesterday, 726 points even w/tinkers on a few rigs. I should have known something bad would happen. Started yesterday off by corrupting the FAH folder (& lost all 51 points that wu was worth) in one rig when trying to squeeze a few more mhz's out of it by upping my oc. Guess that's what I get for being too greedy & not backing up before pushing it so hard. It's an 1800+ already doing 2473MHz (215x11.5). Just had to try & get it over 2.5. Then the power went off for a while. I have 3 layers currently folding on the Overclockix cd. Well there went all that folding....grrrrr :mad: 2 of em had almost completed 51 point gromacs!!! :mad: Oh well....everything’s back up & folding again. Just had to blow off some steam, when I mentioned it to my wife and kids, they just looked at me like I'm nuts. It's like so what to them. Thought I'd share my pain with some of you. Some of you have probably had this or even worse happen. Maybe we need a disgruntled folders support group. :p

Yup, that is the disadvantage of a live CD... I've lost wu's due to the occaisional power failure. But now I have small hard drives or usb pens that I use for hdd-installing the OS or for a persistent home so that I don't lose the WU's. You could even set the boxes to fold onto a windows shared drive, and I could help you out with that. It means it takes an extra minute of running some commands any time you restart (so they reconnect to your server), but it also means the folding directories are kept on a permanent medium..

Wow! that would be great. I really like useing the Overclockix cd except for that one small disadvantage! So how do I go about doing this?

yeah sorry to hear your sotry that really sucsk!! hopefully though that will stop hpapening soon enough

My mom shut the power off to 3 comps, (2 pentium pros 233Mhz, 1 k6-2 @ 450Mhz). She said they made her nervous! The two pentium pros were only 1 day away from delivering their work units too!!!!

Ok, first things first- on your windows box you need to share a partition or folder. DFo this by right-clicking and choose "sharing". Create a new share and give it a name- a simple one-word name will be best. I often just name it after the drive letter.

Now create a user called knoppix on the windows computer and set a password. You may want to go to the advanced options in order to set the password to never expire.


Now on the overclockix boxes-

open a root terminal by typing

su

kill folding by typing-

foldoff

Now mount your remote computer's shared drive so Overclockix can access the share by typing-

mountnetdrive 1 $hostname $sharename knoppix

$hostname = the name of your windows computer
$sharename = the name of a shared drive/folder on your windows computer (keep it simple)

You will get to read some notes about the script and a few seconds later you'll be prompted to enter knoppix's password that is set on the windows computer.

For every other box you should change the "1" to a 2 or a 3- basically each needs to be unique.

This script will create a directory called /mnt/netdrive1, and on subsequent boxes /mnt/netdrive2, or /mnt/netdrive3, etc- that's one place where that unique character comes into play.

Now you can type

cd /mnt/netdrive1
ls

and you should be able to see the contents of the shared folder.

Now run the command

foldnetdrive 1

Again I use the unique character as this script will move your folding directory into the shared drive and name it fold1, or fold2 or whatever.

This script does not work perfectly yet, so you should manually run the following-

ls
^
You just want to verify the folding directory has been moved

If it has, then-

rm -rf /home/knoppix/fold
ln -s /mnt/netdrive1/fold1 /home/knoppix/fold


^ Again with the unique character that should be different if you try to do this with more than one box running Overclockix. What this last set of commands does is delete the original folding directory in ramdisk and replaces it with a shortcut that points to the new location on the server.... That way the scripts foldon and viewfold, et al will still work.

In order to resume from where you left off, say after a reboot of either machine involved, you'd run the mountnetdrive script again. But instead of running foldnetdrive, you run a scritp called resumenetfolding.

resumenetfolding 1

^ Again with the unique character. You may also still have to delete the original foldiong directory in ramdisk and replace it with a shortcut as mentioned above.


Now that's a lot of explanation for a few simple commands, and these scripts have seen some small inprovements in the technomancer version. But here's some examples-


Setup remote folding for the first time-

su
foldoff
mountnetdrive 1 Guru E knoppix
foldnetdrive 1

This is for checking the status-

cd /mnt/netdrive1
ls
top
viewfold


Resume remote folding after reboot of the server-

umount /mnt/netdrive1
mountnetdrive 1 Guru E knoppix
resumenetfolding 1


Resume remote folding after a reboot of the client-

su
foldoff
mountnetdrive 1 Guru E knoppix
resumenetfolding 1

In all these examples I used a 1 for the unique character. For multplie machines use a different character and be sure to replace it in every command where you see I used a 1.

My hostname in the example is Guru and my share name is E.

This will work on both NTFS and Fat32!

Thanks Arkaine!!! I'll give it a try this evening.

Quailane, how long does it take for your Pentium 233MHz computer's to fold....say a 32 point gromac? I have an old Pentium 233MHz computer that's just sitting in my garauge takeing up room, I didn't think that it would be able to make the deadlines. If you're able to make them then I guess that I'd better fire that old antique up & let er fold.

[Fast420A]

I have seen a P166 Make the deadline, barely. If you do set it up, you may as well do Genome@Home with it and Queue up 10 WU's and let it go to town for a month or two. And if it will cost more than $10 or so to get it running, not worth it, just get an Athlon $100 rig up with used parts from the classifieds. :D
