I thought virtualizing really killed the I/O throughput?

Are you running a version of Ubuntu higher than 10.04? I’ve been wondering if I should make plans to upgrade the Ubuntu version as well.

Hey all,

Working on making some upgrades to our FOG servers to increase performance and streamline some maintenance. We currently run FOG on Ubuntu 10.04 desktops with a single hard drive that houses everything. I’ve had the thought of splitting the FOG server storage and the image storage into two devices.

Within the device, the images would be stored on a standard 1TB hard drive for lots of space that will help with temporary transfers, etc. I know you can have /images stored on a different drive so I’m not too worried about that.

Our plan is to install Ubuntu/FOG on a 60GB SSD to really increase performance, especially while network booting a machine while another machine is already being imaged. This will also allow us to backup the OS on our own without having to worry about backing up images.

My question to the FOG community, are there any snags with running an SSD in Ubuntu 10.04 that I should be aware of? I would assume that the amount of I/O produced by an Ubuntu OS that is only used sparingly would give the SSD some longevity.

any advice is appreciated

[quote=“pavlito, post: 972, member: 402”]JBurgin, can you descripe how have you add a WinPE to fog? I try with BartPE… I have add this like the delldiag above, using memdisk, but when BartPe is loading I became a bluescreen.[/quote]

Sadly, I can’t provide much help outside of everything posted here. My WinPE iso is a raw one created from basic Microsoft Instructions. (listed [URL=‘http://technet.microsoft.com/en-us/library/cc709665(WS.10).aspx’]here[/URL], skipping step 4) BartPE tends to be a heavily customized one so I would say that something in BartPE doesn’t like being PXE booted.

what I did instead, to provide me with some useful diagnostic applications on a regular WinPE ISO, is place several portable apps on a shared folder on one of my servers and then use the ‘net use’ command to map a drive letter to that server once loaded in winpe, where I have access to all my apps I need. This cuts down on the iso file size and allows me to constantly update the applications without updating the ISO. This obviously will not work if WinPE doesn’t support my network card, but so far I’ve only had it happen on one model.

Hope this can help.

I believe it should be said, with the usage of memdisk, that you should careful how big your ISO is. As it’s being loaded into memory, if you have a large enough amount of ram, it may fail out.

But, thanks for the quick primer. I’ve added isos to my boot menu in the past and they’re extremely useful. I have a WinPE iso added to ours that gives us access to Windows boot recovery, partition tools, chkdsk, and not to mention network drive access (90% of the time) to run portable apps such as Spyware scanners, etc.

I’m using FOG to schedule a wakeup of 30 computers at the same time every morning during the weekday. We used the cron style scheduling, however the computers are not waking up. We want to go into the Schedule Tasks section of Task Management to delete the scheduled wakeup, but the Scheduled Tasks list is empty. Do cron style scheduled tasks (repeatable tasks) show up in Scheduled Tasks or is my installation messed up?

Thanks for any and all help. We’re running Fog 0.32 and Ubuntu 10.04.
