Horrible performance on migrated server
-
[B]UPDATE[/B]:
Started over with a completely new installation of FOG server, same IP address, did not migrate the images, used the master computers for each image to create new images. Uploaded a new image from the X201 master which went much faster and then attempted to download to 2 different X201 machines (all have the same hardware) and both of them bomb out at different points during the deployment. This is the only image that doesn’t complete and they stop at different points during the deployment. I tested the NFS setup again with the same results, took about 11 minutes to copy this image straight down to the desktop. These images were working like a charm from our initial temporary FOG server, so the only thing that’s new is the new FOG server.Any ideas? Reloading our machines from scratch is a nightmare with all the additional software and I have to get a bunch of these machines knocked out soon.

Have you tried Ubuntu 10.10 or less because I have seen post of people saying they had issues but not sure if it was imaging. So one image uploads fine but the other two crap out at different points but never fully upload? Have you thought of trying a different kernel for the PXE upload and download part?

I actually haven’t tried reversing the install, but maybe that’s the way to go and I haven’t changed any of the Kernels, so far this is the first time I have had any trouble with our network or the FOG server. I’ll have to try and find the older versions of the Ubuntu downloads, as I’m pretty sure I don’t have a CD of it.

[B]UPDATE[/B]: Ok, so after a lot of struggling, and some physical and OS changes, here’s the final solution (at least I hope so). I rolled back the OS via complete reinstall of the OS to Ubuntu 11.04 as 10.04 didn’t include the NIC drivers for this new of a motherboard and I wasn’t going to try and compile drivers for the Network Card (I already have enough on my plate without that task).
I also physically moved the FOG server into a rack in the server room and am direct now into the Pro Curve which eliminates any in wall wiring or cabling issues with it in my office. So far I’ve uploaded 2 of the problem images in less than 12 minutes and downloaded and imaged 2 PC’s with the troublesome X201 image in less than 10 minutes each with no trouble on either one.
Unfortunately I was so exasperated with the issues I ran across I didn’t do this in stages to find out what the actual problem is so I’m not sure this post will be useful for anyone looking at the same issues.
One thing I wanted to ask, what does mounting the NFS volume actually indicate, since I was able to successfully mount it and copy down the image with a very respectable speed? Basically does that indicate network problems or FOG problems? I’m sorry I’m not following the diagnostic pattern on this test.
Regardless of all of this thank you both for your help with this, I’m pretty sure I’m back and imaging happily.

mounting the volume NFS and bringing down the file helps to determine if the problem is in the FOG kernel on the client or something with the server, or something in the network. Bringing up a liveCD version of ubuntu and doing this removes the FOG client kernel from the mix and let’s you know whether the slow down is on the server or network. If the file transfer over NFS to a liveCD was slow, then the problem is in the network or the server, not the client. If the speed was not slow, then the problem is most likely in the FOG client kernel.
If the problem was found not to be on the client, then you can troubleshoot the network by removing any intermediate equipment by imaging directly from the switch to which the server is connected. If the problem still existed, you could try an “out of the box” switch with just the server and client connect and no uplink to the normal network. The would help rule out a switch config problem. If it’s still slow after all this, it’s probably something on the FOG server, such as disk performance or NIC driver issues.

Hi , iam able to boot with the network by pressing F12 iam able to see the logo of FOG but not able to boot with the images some where i don’t know where to copy the iso images i think its 100 % problem with the images i need some one help to sort it out asap.

Manjunath, please start your own thread and include what OS the server is running, what version of FOG, what model and brand of clients you are trying to image, etc. The more information you provide, the easier it will be to help.

Hi Dave, could you please confirm that you have been able to upload from and deploy to your Lenovo X230? Since this particular model is not on the ‘approved’ FOG list, I’m NOT looking forward to getting 25 of them tommorrow… Any particular setttings used?

Hi Klaus, probably already too late here but for notifications sake, I’m able to do the X230’s no problem. I had to restructure the master to a single partition and make sure the boot flag is set to the primary OS after Windows 7 sets up it’s utility partition. I also changed the AHCI settings to compatibility mode. Other than those things it went smoothly.
