@george1421 I’m still confused.
Its highly possible that I’m ignorant to the features you have added to the trunk builds, plus I’m not doing a good job of explaining the current situation were I think FOG is highly capable to accomplish this with a few adjustments. I’ve looked through the wiki to see if there was something similar to what I need to do. The only thing that came close was https://wiki.fogproject.org/wiki/index.php/Managing_FOG#Storage_Management (the second graphic that shows the multiple storage groups). This is the POC concept used to setup my test environment.
I took that previous drawing and build this sample layout.
In this scenario I have these requirements (almost sounds like a school project):
- Will be constructed with 3 or more sites
- Connection to each site will be via a connected via a MPLS 1.5Mb/s link
- Because of the slow link each site must have its own FOG Deployment server to provide PXE booting
- Each of the sites could have one or more VLANs each with their own subnets isolated by a router.
- Corporate images will be created at the HQ site and distributed to all sites. There is a potential that each site could have their own images for specific purposes. So each site must be able to capture images to their local deployment server.
- On a corporate deployed image there may be a reason to recall or block deployment of a specific image across the organization (such as a detected flaw in the image).
- The location plugin is installed on all FOG servers. The only location that will have more than one locally defined location is LA
To clarify the above picture:
In the HQ location there is only one deployment server HQMasterNode
The LAMasterNode and ATLMasterNode are connected back to HQ via a MPLS link (right now this is all done in a single virtual environment)
In the LA site there are 3 FOG servers. One FOG deployment server, One FOG storage server and One FOG Storage server with PXE booting enabled (I think that is an option). The LA site also has two VLANs with about 700 nodes distributed across the VLANs. There are two defined locations for the LA site (LA_BLD01 and LA_BLD02)
The ATL site only has one FOG Deployment server and one storage node on a single subnet.
This is how I have the test environment built in my test lab.
As I posted before I seeded the images in the HQMasterNode with images from my production FOG server. No replication happened between the HQMasterNode, LAMasterNode or ATLMasterNode until I created the first image definition on the HQMasterNode. Once that first image definition was created all images that were seeded on the HQMasterNode were replicated to the other two nodes in the HQ Storage Group. This worked great, now all image created on the HQMasterNode were located at the site FOG Deployment servers. The images did not get distributed beyond each sites MasterNode though. On the ATLMasterNode I created a single image definition and then the images were replicated to the ATLSlaveNode01.
The first issue I ran into was even though I created all of the image definitions on the HQMasterNode those definitions were not copied to the LAMasterNode or the ATLMasterNode. Somehow I need to get those definitions (I’ll assume the same for the snapins) from the HQ deployment server to each site’s deployment server. This could be accomplished with a mysqldump of the tables before the replication starts and then picked up at the remote end and an mysqlimport run. Or by making url calls to each of the sites deployment servers to update their database with the image information.
