@george1421 I had time to spin up two new fog servers in my test area, one for imaging and one for client interaction. The client interaction one is set to connect to the DB of the imaging one. I also imported the certs from my production machine to both.

Unfortunately I ran out of time before I could actually test anything. Holding pattern until Monday I suppose.

@george1421 I couldn’t resist… I remoted in and took a quick look. It seems to be roughly 1500 hosts. I am starting to realize that this situation may be more about me wanting to try this than actual necessity.

That being said, in the past, I did have to extend time between client checkins because of it absolutely consuming my fog server’s resources.

In your opinion, is 1500 hosts enough to justify this? I still want to do this regardless as I have caught the improvement bug already, but I would like to hear what you think.

@george1421 I will look tomorrow as I am off today. I know it is in the 1000’s. I like your layout there though. This seems quite doable.

@george1421 I definitely did mean one database. I don’t quite know why i said cluster! I am in the use-case creation stage so this may not even take off, but I will wait for @Wayne-Workman to chime in since it seems at one time he has done this. The post I was referring to was his post in this: https://forums.fogproject.org/topic/12993/use-an-external-database

I am really willing to experiment here if it gets off the ground.

I realize Wayne’s visits are fewer now that he is in a different setting and I am willing to be super patient.

EDIT: @astrugatch I will explore this too but is that a free solution?

I wanted to make a post about my theoretical foray into possibly setting up load balancing for both HTTP and DB connections for my fog setup due to the number of clients (and to play around too!). This is all inspired by an old post by @Wayne-Workman who I hope can help me if he has time. I am in the research phase right now but basically here are my thoughts:

A cluster of 3 fog servers tied together by HAProxy for both Http connections and a Galera MariaDB cluster.

I am reading up on the viability of this solution. Anyone else have any thoughts?

@Sunks I use this method to clean out tasks and other odd database junk:

I really only do the first batch of cleanup commands in this link, deemed the safe ones to perform.

@rinfog said in Image deployed to laptop but hangs at Exiting PXE boot when not hardwired:

Yes the machine boots into Windows fine as long as the Ethernet cable is connected.
SATA operation is set to AHCI.

If you boot into the machine with it hard wired, does Event Viewer show anything out of the ordinary for previous failed wireless boots?

@rinfog said in Image deployed to laptop but hangs at Exiting PXE boot when not hardwired:

The machine already joined the domain and installed all snapins (while connected via Ethernet).
We did use sysprep on the image prior to capture.

Ah, so this is not the first boot after imaging… Very strange. May I ask what SATA operation you have enabled for the client? We always recommend AHCI and not RAID ON. You should be able to verify this setting in the bios somewhere.

@rinfog said in Image deployed to laptop but hangs at Exiting PXE boot when not hardwired:

FOG Server = 1.5.7
FOG Client = Smart Installer 0.11.16
FOG Server Linux distro = CentOS 7
I am not trying to PXE boot over wifi, this is indeed post-imaging the client.

Thanks for the information. I also just saw in the OP that you are getting a black cursor when manually booting into Windows without it being hardwired. May I ask if you are attempting to join a domain at all with the FOG client or another method? Do you sysprep the image as well prior to capture?

@davemccracken no harm no foul man. I am learning linux facts every day and I have been a FOG user for about 6-7 years. Many a time I find myself googling how the heck to do something still. Far from a master here.
