Standard storage nodes or multiple TFTP servers in MPLS cloud?

moses

I’m getting FOG set up and everything is going swimmingly.

I’m confused about storage nodes however. We have multiple sites that are all interconnected over an MPLS circuit, and each site has it’s own DHCP server and scope/subnet with static routes between everything. Should I set up each site with a standard storage node? Or should I follow the instructions to set up multiple PXE/TFTP servers on the storage nodes?

Ultimately what I want is for each site’s computers to directly get the image from the storage node onsite. Will the standard storage nodes accomplish that?

1.2.0 will not. However FOG Trunk will.

If you insist on using 1.2.0 (which is quite old), you’ll have to setup TFTP on each one manually. FOG Trunk has this integrated into the storage node installation.

Is this where I want to be?

Yes

@george1421

You will also what to setup a storage location for each physical location. Then assign a storage node to that location.

The trunk build sets up the tftp settings for you where the 1.2.0 stable does not. Just realize that the trunk version is still in beta so there’s a chance there are still bugs lurking about. If you find them and report them in this forum they will be addresses pretty quickly. You may also have to update your FOG environment a few times as updates are pushed out. Once you find a stable build you can sit on it for a while as long as you don’t need one of the new functions.

@george1421 I know it’s likely a matter of opinion, but would you recommend using Trunk in a production environment if there’s a possibility of bugs?

george1421

@moses It depends on how much risk you can tolerate. Bugs in the trunk version tend to get a lot of attention so they get resolved pretty quick. (0-3 days for simple ones). If you can tolerate that risk then the trunk build is fine.

If I had to deploy 100 systems by this friday without exception then I might think otherwise.

I can tell you that the 1.2.0 stable version does not handle gpt disks memblock disk, and efi booting very well at all. The devs have everything worked out except the efi booting on some of the new surface pro 4 class tablets (hp and lenovo of this also has issues).

Okay, thanks for both of your help!

Quick question regarding this setup on trunk: for the DCHP servers that are each site, should they point to the Master FOG server at the HQ location, or should they point to the storage node that is onsite? Keep in mind the goal is to have clients download images from whichever server is at the site they happen to be at.

Either will work with newer systems and most older ones, but based on my recent experience with this, I would recommend you setup each site’s DHCP to point to that site’s storage node.

@Wayne-Workman I set the DHCP server up at one remote site to point to the local storage node that is set up there. I verified that the images are replicating normally.

However, when testing PXE boot with a VM in Hyper-V, I get the following:

When I take a gander at http://192.168.2.66/fog/service/ipxe/boot.php:

#!ipxe

autoboot```

This line doesn't look right:

console --picture http:///service/ipxe/bg.png --left 100 --right 80 && goto console_set || goto alt_console

@moses That error your seeing was literally just fixed yesterday. re-update the main and nodes and then re-run the installer on them. You can speed things up by using the -y argument like this: ./installfog.sh -y

See if the boot.php file displays something different afterwards.

moses

@Wayne-Workman Strange, as I installed it today. I’ll pull it again and run the installer again.

Please provide your apache errors from your storage nodes. Here’s the command for Fedora / CentOS
tail -n 100 /var/log/httpd/error_log

Use the codebox feature to post it here.

moses

@moses Ran the installer on both the main and the node, but the boot file is unchanged on the node. Same error when I attempt to boot from it.

Anything else I can try?

@moses Are you able to access the web interface without any issue? If yes, check to see if the settings FOG_WEB_HOST (your FOG server IP) and FOG_WEB_ROOT (normally /fog/) are properly set. The mysql errors don’t look good. Is the MySQL DB running (service mysql status)?

@moses said:

[Wed Feb 24 16:19:26.046943 2016] [:error] [pid 1345] [client 192.168.1.116:61510] PHP Warning: mysqli::real_connect(): (HY000/2002): Connection refused in /var/www/html/fog/lib/db/mysql.class.php on line 30

The quoted line is of concern.

As @Sebastian-Roth requested, can you restart mysql service? Also, can you double check disk usage on the server with df -h?

@Sebastian-Roth I can access the web interface on the main FOG server with no issues, and there are no problems there. Mysql is confirmed to be running. This issue is with a storage node, and the web interface is disabled with the “This is a storage node, please do not access the web ui here!” message.

@Tom-Elliott Plenty of storage space to go around on the node, so no problems there. This the df -h output on the node, the main server is pretty much the same, with about 30 GB of images taken up on sda1:

Filesystem      Size  Used Avail Use% Mounted on
udev            1.9G  4.0K  1.9G   1% /dev

/dev/sda1       290G  3.6G  272G   2% /

none            100M     0  100M   0% /run/user

Standard storage nodes or multiple TFTP servers in MPLS cloud?
