Using Fog over subnet
-
OK thanks, I think this is my last question … do I need to configure fogserver to accept ip address from my other subnet.
for example HQ is 192.168.0.x
subsite is 10.10.10.x -
@cnkpadobi There should not be anything to keep the fog server from responding to those other subnets. Just make sure you have the gateway set correctly on the fog server and it should route to the other subnets without issue.
-
When trying to pxe from subnet I get this message… it work fine from headquaters!
-
@cnkpadobi Ok at the remote site, what is your dhcp server?
What do you have configured for dhcp option 66 and 67?
Do you have a fog server at that location or only HQ?
By the way the picture explains more than just the error message. Well done!
-
@cnkpadobi The picture you posted is showing “No boot filename received”. This sounds like the DHCP in this subnet is handing out IPs but not nextserver and filename information for PXE booting. What kind of DHCP server is serving this subnet and how are option 66 and 67 configured?
-
@george1421 @Sebastian-Roth The issue with pxe boot has been resolved.
-
@george1421 Thanks George… another question,
If I set a cronjob up in linux to start and stop the replication. Which process do I used to do this.
-
@cnkpadobi Not sure I’m following…
But the name of the service is FOGImageReplicator
You could create a bash script to stop and start the service or call your service manager directly from cron. You will probably edit the /etc/crontab file to set this up.

@george1421 I ran a replication overnight and was wondering is there a way to know for sure if the job completed. When I look at the log file I see the following. It hard to tell but the time on the log is off…

[06-20-17 2:34:10 pm] * Found Image to transfer to 1 nodeMy last question is… Since this location is physically close is there another way to get the image to the storage node without replicating it over the network
-
@cnkpadobi Apache/php may be using the wrong timezone.
As for the replication, only other way would be to manually copy the image folders to external storage and then attach that to the other machine when it’s done and copy it back to their appropriate locations. Should work, but I’m not sure why you’d want to do this.
You can change how often the service checks in in FOG settings instead of using cron jobs, by the way.
-
@Quazz Well wanted to jump start getting that image over to the remote location so my staff can start imaging without waiting for the long replication time to finish over the 1.5mpls. I only want to move 1 image over to that storage mode.
Thanks I will check that.
How I change the service checks…
Is there a way to tell if the replication completed or what percentage it is at?
-
@cnkpadobi FOG Settings -> FOG Linux Service Sleep settings
Not sure if there’s an easy way to track if replication is finished, to be honest. I don’t use multiple nodes myself, so not an expert on replication specifically.
