I’m on CentOS 7 using FOG 1.5.0. Can anyone tell me how to schedule image replication for after hours? It’s killing our daytime bandwidth to have it replicate to so many storage nodes during work hours. I’ve read that I need to use a cron job to start the service and then another cron job to stop it. Can anyone tell me the exact Linux commands to do this? I’m a Windows guy and this particular Linux command is evading me.

The problem seams to have self resolved. This can be closed. FYI, nobody changed any settings. It just started pulling from the correct node on its own.

I’ve gone ahead and disabled all other storage nodes except the master until I can get this figured out. It’s trying to pull images from nodes where those images don’t even exist???

@george1421 Yes I do

Please help me understand how FOG chooses what storage node to pull the image from. I thought that if you assigned a storage node to a specific location and then assign a host to that location that it would only pick from that storage node. Here’s my situation.

I have one master node and I am building up over 30 remote storage nodes. I have 3 “child” nodes in the same storage group as the master and the master is correctly replicating images to the three child nodes. I have assigned each child node to a specific location.

Whenever I image a new system now it seems to randomly pull the image from any one of the 3 child nodes. It doesn’t matter if I tell the host to only use a specific location, it still pulls the image from one of the other nodes. What am I doing wrong?

This has been resolved. I updated to FreePBX 14 (CentOS 7) on the golden image and it correctly sets up the NIC’s on the imaged machines. Thanks for the help

Okay I feel really stupid. Replication was not working because the server system time was not set correctly. Go ahead and marked this solved

@wayne-workman Yes it has been set to permissive on both servers

@george1421 It’s a VM running CentOS 7 and I ran the installer and chose “storage” when prompted. Yes I can ping both ways

@tom-elliott Web interface says 1.5.0. I checked out dev-branch and installed today.

I just tried my first storage node config. I built a VM using CentOS 7 and latest FOG trunk build. Everything seemed to go smoothly during the install and when I was done the storage node immediately showed up on my master FOG server. I created a group and location and assigned one image to it for replication testing. I called the storage node “Park City Fog VM Server” and here is what the log shows:

Why does it say that it’s offline? I can putty into the node just find and like I said it automatically talked to the FOG master server and added itself as a node so they must be talking to each other.

@george1421 I’m going to try and build a golden image using FreePBX 14 (the latest stable build) and see if the issue persists

@george1421 FreePBX 13 is what we’re using. Here is a screenshot of the golden image that I want to capture and then deploy:

And here is the image deployed. Notice the missing IP’s. I need to be able to deploy this remotely to a site and then take over using SSH but they aren’t getting any DHCP IP’s:

I did try deleting the file “70-persistent-net.rules” and rebooting but it didn’t do anything

@sebastian-roth I believe that FreePBX is a version of CentOS which is Red Hat based. I try some of your suggestions and report back. Thanks.

@Sebastian-Roth , are you saying that in my captured image I already have static naming setup or that I need to first have that setup before I capture? I’ve ready various articles and I’m not sure I follow the logic. This is the last piece that I need to get right before I can start imaging our PBX systems all over the country. Need to have network access after the deploy.

After capturing and then deploying a Linux image with FOG I have lost all my network configs. I am trying to build up a base image for FreePBX (CentOS) so that I can image to any fresh hardward. Upon testing, everything works but I lose all the network config. The original image has eth0 and eth1 with DHCP. When I deploy that image to fresh hardware (exact same type of machine as original) the OS shows eth2 and eth3 and they both have NO IP’s and no network access. Any thoughts?

Okay that was it. Thanks. I reset my image using ext4

What now? How do I get FOG to shrink when capturing?

@tom-elliott I think so yes. How do I tell?
