Diskless Booting w/Linux - My Journey
Since most are running linux anyhow, they don't have a video card, which is fine since I access them through SSH... Well, the next step for me was to remove the hard drives, since it seemed a waste to use a 30GB hard drive, only to have a bare bones install & F@H on it... (not to mention the noise & power consumption)... I saw the one thread here about the booting off of a CD-ROM, which while nice, still required a CD-ROM... and I'm going for BARE MINIMUM! My goal was to have just a master server, and have the rest boot from their NICs to it... First I came across a link shroomer gave me about a "Prime Monster" with a guy using LTSP... So I gave that a shot last night... Basically you install the RPM which has the base OS for the systems to boot from, and edits your config files so you don't have to do much... I was able to get a machine to boot off the network, and I could access the internet by IP only... It is having "resolver" issues... I found a few threads really late last night that I am going to try out, but if that fails, then I'm going to have to create my own stuff and do it all by hand (which shouldn't be that difficult). Basically the theory goes like this: 1. Master Server holds image for remote clients to boot from 2. Client turns on, NIC makes DHCP request for a boot image 3. Master sends the kernel and other stuff so system can boot 4. Usual boot process, most stuff is RO over a common NFS mounted file system, other files are created & stored on a local RAMdisk on each client. 5. F@H folder is unique for each client, and is NFS mounted as RW. Sounds easy, which it should be, but there are just a lot of little caevats to work out... If anyone has experience setting up diskless workstations please let me know, I could use all the help I can get... |

Well I hope you get this solved I would be really interested in doing this...Is there a maximum to the amount of satelite systems that can run off of 1 server ? If so how many ?

You only need 1 copy of the main file system, and kernel. You can either store F@H on the server, which each client will need it's own directory (~10MB Max), or you can have each client create a RAMdisk, copy a clean FAH client & cfg file to it, and then run it on the RAMdisk. The only downside is, if you reboot or loose power, you loose all your work... So storing it on the server seemed a little safer at a minimal amount of disk space. However, since I think I am going to end up building a new kernel, I might go ahead and make a 12 or 16MB RAMdisk and do it that way, since it would also make upgrading to a new F@H easier.  Only time will tell... Wish me luck... If I get this going smooth, then I am going to save up some money to buy some boards & such for a nice ghetto cluster... If/When I get this thing running smooth, I'm going to do a complete write-up with files & everything so other people can set them up too.

Sounds Nice I will wish you luck on that then I hope it goes smooth
I would probably be doing the HD method since I have about 4 to 8 power outages a year in this location

EUREKA!!!! I got it to work... just the stupid gromatics server is down now... LMAO!!!
I just needed to install one extra .rpm and BAM, it worked... would of been nice if THEY INCLUDED THAT INFO!!!! Anyhow, I'll be posting a full how-to in the next couple days, it really wasn't that difficult now that I know the full extent of what to do.

Yeah, I'll probably write it up this weekend, it took a little more tweaking after I posted that previous message, but nothign complex...
It's a breeze to setup extra machines... you just have to put their MAC address in the DHCP config, edit one other config file, copy the F@H folder for the new machine, and you are set... wham, bam, thank you mam...

I'll probably crank out that writeup this weekend while it's all still fresh on my mind, it shouldn't take that long to crank out...
I'm glad I was able to do it all with LTSP RPM's... makes it much simpler for other people to install / config... And, the good thing is, with a little more modification, you can use a machine as a full fledged remote X-Terminal

Yeah, it's only for linux...
Even if you don't know anything, I think if you can get past the plain linux install then you already accomplished the hardest part... Really this guide is only for people with a lot of computers that they know will be for F@H... |
