Storage Node

[Goll420]

We are running FOG from a segregated network which doesn’t exclusively have access to the internet. We are doing it this way for now until I get the Cisco kit in to create the VLAN and allow me to split it off that way.

However, going to add a storage node into the mix to allow for increased throughput when deploying, and I hit a problem with the installer. It needs to be online for updates, but then if it can’t contact the database during the install; it seems to fail.

If it does fail and aborts as it cannot contact the database; what are the steps needed to continue the install? I’ve added the storage node to FOG but I don’t think it’s working, I can’t see any folders under /var/www/html for images etc.

Your issue isn’t specifically clear.

To install a storage node you need to have both internet and 100% full access to the FOG server, because that is where the database lives. The storage node is a deploy only system needs access to the FOG server to operate. The storage node only needs internet access during setup. Once that is done the fog server can run on an isolated network.

@Goll420 To me it seems like you are mixing up things here. Let’s try to sort this.

While I do understand what you mean I don’t think adding storage nodes is the best way to achieve that. There is multicast to deploy to a huge number of machines at the same time with way less load than you would have deploying singlecast.

It needs to be online for updates, but then if it can’t contact the database during the install; it seems to fail.

Yes it needs to have access to the internet while running the setup but as well it will need access to the master node database in general. There is no way to run a FOG storage node without network access to the master node!

If it does fail and aborts as it cannot contact the database; what are the steps needed to continue the install?

While you can run the FOG installer with command line option -X to ignore failures and proceed I would not use that in all cases. Please describe in more detail why your storage node is not able to contact the master node and why you want to use a storage node setup per se.

I’ve added the storage node to FOG but I don’t think it’s working, I can’t see any folders under /var/www/html for images etc.

If the installer does not run all the way to the end it won’t populate all the files.

@george1421 Thanks, I’ll put another network card in for the setup. That should sort it.

@Sebastian-Roth Thank you, I did forget about using Multicast. I’m running a job now using it and it’s immensely improved bandwidth utilisation!
