Multicasting - Not The Master Node
-
@Joe-Gill Does “Where our main fog installation is” have the images as well?
-
@Tom-Elliott
Negative. That /images directory is empty. -
@Joe-Gill So what is the storage node? Is it a nas?
-
@Tom-Elliott
Yes essentially. But it is a running FOG Storage Node. -
@Joe-Gill So it has a full install of FOG?
-
@Tom-Elliott
Yes it does. The storage node version. -
@Joe-Gill Can you check its multicast error logs then? Will be more useful info.

This is all that’s on the Storage node multicast.log.[07-27-16 1:10:11 pm] | Sleep time has changed to 10 seconds -

Could I create a new storage node (.17). Give it the IP of our server (.17). Set it to slave. Let the images migrate back to the /images directory on the server. Then after all images are copied set the storage node (.22) to slave mode.
Would this work? Or is their an easier/safer method?
I’m stuck at the moment with Unicast. I’m trying to push 10 images and my time remaining is 6:30:00… I’ve got about 300 more to do!
Thanks!

@Joe-Gill Are you sure the “storage node” isntallation is “storage ndoe?” It seems to be looking at it’s own database. (BTW, fogserver should NOT be the same on multiple systems.)
-
@Tom-Elliott
What’s the easiest way to verify? -
Well I can tell you that when I navigate to our 172.16.1.22/fog in the web browser it says this…
This is a storage node, please do not access the web ui here! -
@Joe-Gill so 22 is supposed to be the master node but the logs you’re giving us are for .17? Is 17 the main GUI or the storage node? Please understand I’m trying to help but getting totally conflicting information.
-
@Tom-Elliott
Interesting…
17 is supposed to be the master node.
22 was set to the master node somehow.17 is the main GUI.
22 is the storage node.I think I know what happened. Initially I had a FOG server, a FOG storage node, and a FREENAS storage server setup. FREENAS was giving me problems so I nixed it. When that happened I reset my Storage Node on the server. I believe I misunderstood the syntax of what the Storage Node IP was on the gui and put the wrong IP in there.
Does that help?
-
Any thoughts on this?
I’ve been stuck unicasting all day… My 10 machines still haven’t finished cloning… This lab is only on a 100MB switch though. ugh!
-
@Joe-Gill My my thought are this:
Why do you have 2 fog servers setup on the same subnet? There must be a technical reason for this?
What precisely do you have configured for dhcp option 66 {next-server}?
If you have dhcp option 66 pointing towards 172.16.1.17 how will the storage node 172.16.1.22 ever be used if the location plugin is not installed and the clients homed to that server?
But more to the point why do you have 2 fog (devices) installed on the same subnet?
-
As for the 2 FOG devices on the same subnet… I had no idea it was an issue. We have plenty (256) of subnets available. I never had a single problem multicasting last year with this setup like this. Only occasionally would I have to go in and manually clear the FOG que when I had something else (bad network cable / task didn’t delete properly / ect) fail and needed to reset things.
We don’t have the FOG server serving DHCP. We have a Windows server doing this (I’d rather go Linux but the other admin does not.) So as for option 66, I don’t know. The only thing we set on the DHCP server was for PXE to point to our server IP (172.16.1.17) in DHCP.
-
@Joe-Gill said in Multicasting - Not The Master Node:
As for the 2 FOG devices on the same subnet… I had no idea it was an issue.
It’s not an issue to have 2 fog servers on one subnet. The question is why (technically) do you feel you need to servers?
he only thing we set on the DHCP server was for PXE to point to our server IP (172.16.1.17) in DHCP
So only the Master fog server is being used for pxe booting.
Unless I’m missing something I don’t see your storage node being used at all. Since you don’t have the location plugin, I don’t see the target computers will know about the storage node.
-
Initially when I set everything up, I was under the impression that you got better overall performance having a separate storage node. Also, I thought it was necessary in order to do MulitCasting. If you can do everything from 1 server that’s great news!
What is the purpose of a FOG Storage Node? I thought that was just to store images? One thing that I may do is migrate the Storage Node to a different physical location in order to increase performance but that won’t happen this Summer. For right now my big issue is that all of my images sit on the storage node Images directory and none reside on my server.
Yes only the Master Node (172.16.1.17) is being used to PXE boot. Everything works great there.
On a side note… I will be building a Debian server to house my FOG server in mid June. So I can clean all of this up then. I would love to know how to improve things as this is all still new to me and I am still learning.
