We’re having difficulties with the 10GBe network card on client.
We’ve Fully disabled onboard NIC on the system (Bios).
System boots PXE (TFTP/http)… but when it wants to mount FOG it suddenly said no DHCP on ENP12S0 nic. Like it’s expecting to receive DHCP on onboard nic. Dident expect that…

Lets just be sure I understand correctly.
You can pxe boot into the fog iPXE menu. When you select something like full registration or pick imaging both bzImage and init.xz is transferred to the target computer. The target computer then starts FOS Linux, but during the boot of FOS, you get to a point where it can’t get an IP address or contact the fog server, it tries 3 times then gives up? Is that where its failing?

@Mokerhamer Something happened with the picture upload. You need to wait until the image appears in the right edit panel before submitting your post.
OK it sounds like FOS Linux doesn’t have the driver for your network adapter.
Lets start out by having your schedule a debug deploy/capture to this target computer. When you schedule the task tick the debug checkbox before you press the schedule task button.
PXE boot the target computer, after several screens of text where you have to clear by pressing the enter key you should be dropped to the FOS Linux command prompt.
At the FOS Linux command prompt key in the following and post a the screen shots here.
ip link showlspci -nn|grep -i netAlso what model of 10G adapter are you using?

@Mokerhamer If you have this nic in a running windows box. Will you get the hardware ID of it? OR from the FOS Linux run the lspci command as I’ve outlined below. I’ll look it up to see if linux supports that card.
The 10G stuff is new and may not be enabled in FOS Linux. Having the hardware ID will help (i.e. 8086:1AF2 made up number, but that is what I’m looking for)

@Mokerhamer That card driver should be included with FOS Linux it has been in the linux kernel since 4.7. I checked and its enabled in the FOS Linux build config: https://github.com/FOGProject/fos/blob/master/configs/kernelx64.config#L1447
From the FOS Linux command prompt key in
ip addr showuname -aand post the results

@Mokerhamer Well this is a good one. It should be working.
At the fos linux command prompt key in
/sbin/udhcpc -i enp11s0 --nowthen do an
ip addr show -
@george1421
Done

@Mokerhamer Ok at this point, time fixes your problem.
So if this was a 1GbE network I would say on the switch you are connected to has standard spanning tree enabled. Again if this was a 1GbE network I would recommend that you enable one of the fast spanning tree protocols like RSTP, MSTP, fast-STP. I don’t know if that translates to a 10GbE switch or not. I know on our hybrid switch 100/1000/10000 I have MSTP enabled because we have multiple stp zones.
-
Reboot? or a command to start cast? Checking out our switches meanwhile
-
@Mokerhamer You are probably better to cancel the task on the fog server then reboot. If you were unicasting and wanted to single step through deployment you would enter
fogat the FOS linux command prompt. You may be able to do that with a multicast, but I never tried. -
Resolved. Spanning-tree was not enabled on the switch port that was directly attached to system.
spanning-tree portfast on the port solved it.What for 10GBe switches are you using? i might purchase the same ones ( we’re seeking for 10GBe switch to test deployment)
-
@Mokerhamer I wanted to clear up my first reply. I’m sorry, I didn’t want to seem so negative and I didn’t fully understand what this encompassed. I apologize if I came off as a meanie. I now see you have really good ideas/plans (and the equipment to back it up). Thank you for supporting the community through awareness and testing. I wish you the best for your trials and await the results!

What for 10GBe switches are you using?
Its an older kit, Procurve 5412zl at our core switch and inside data center.
That’s great it was something simple like spanning tree. The issue is with standard spanning tree is that it doesn’t start forwarding data for 27 seconds once the link is established. Well during the pxe booting process the link “winks” 2 times. The first as iPXE takes over from the PXE rom, and the second time is when FOS Linux takes over from iPXE. FOS Linux boots so fast that by the time the port starts forwarding data FOS Linux has already given up.
Standard STP listens for a BPU then forwards. Fast-STP forwards first then listens for the BPU.
-
Procurve 5412zl does not have 10GB poorts? or i might have the wrong product infront of me
-
@Mokerhamer There are 10GbE modules for it.
-
Ever tried multi-casting on a full 10 GBE network, including clients having 10 GBE? i am really wondering what ZSTD with high compression on a 10GBE network. Prepared several machines, from 16 GB till 64 GB with strong cpu’s.
Hardware will come in Monday/Tuesday and we will push the limits curious!
