SOLVED FOG Upload Slow/Slowing

  • Morning everyone,

    I’m currently having an issue (linked to my previous post found here: where I’m trying to upload a Windows 10 image, but the rate of the upload is constantly decreasing. It started out at about 4GB/min but now it’s decreased to 930mb/min. I’ve also noticed my FOG server is a little slow with basic commands (like logging in, listing directories, etc.) I have 50GB free out of 200GB, so I don’t believe it’s the hard drive capacity. It has 1GB of RAM as well (running as a VM on a Windows 2012 R2 host).
    Does anyone have any ideas as to what could be causing it? I really need this image to be uploaded as soon as possible.


  • @RobTitian16 Just seems to have been a slow network day I guess as it’s running through fine now at 3GB/min 🙂

  • @Wayne-Workman I’ve checked all of those things… I’ll see how it goes when I upload the next image tomorrow morning.

    The VM is type 1.

  • It could be a bad patch cable, a duplicate IP, a failing HDD, failing RAM, a number of things.

    could be the base OS as well, you might try to reboot it.

    @RobTitian16 Is the VM running on a type 1 or type 2 hypervisor?

    Type 1 (ESXi, Hyper-V)
    Type 2 (VMWare Workstation, VMWare Player, qemu, virtual box)

    Loosing connection will cause the network connection to slow down as you noted. The imaging solution assumes there is network congestion at the higher transfer rate, so it slows down until it finds a rate at which there are no errors.

  • @Wayne-Workman Apologies - I wrote the above in haste.

    FOG version is 8169.
    OS - Ubuntu 14.04
    Image OS I’m attempting to upload - Windows 10.
    Attempted a reboot to no avail. I also tried deleting the host and re-adding it to FOG to no success. The only thing I didn’t do was delete the image and re-add it, but I shouldn’t need to, should I?
    I noticed that the upload in progress repeatedly seemed to lose connection, at which point the rate would decrease. When it picked it up again, it would be much lower than when it started out. For example, it started at 3GB/min, but then decreased to 2, and then 1, and finally 600mb/min. Sometimes the rate went up slightly - say from 1 to 1.1GB/min, or 630 to 650mb/min and would then seem to resume the upload at that new speed.
    I’m going to try a different system later today to see if I can upload it then.

  • @RobTitian16 fog version, os version, and try a reboot.
