@Daniel-Miller said in FOG client with dual boot image:

We actually have a related issue in some of our student labs with a configuration management product (Deep Freeze) that discards changes to the filesystem; the machines in question lose their trust relationship whenever they are rebooted. I’ve mulled the issue over a bit and have some testing slated to attempt using junctions to offload the token storage location to a non-managed volume. I think the same approach might be viable for a dual-boot system through the use of junctions and symbolic links to tie the file locations containing the token in each operating system to a 3rd commonly readable file system. Thoroughly untested, mind you, but should be a viable workaround.

Try to add correct exceptions to Deep Freeze (files, folders and registry keys), take a lot of care with installation paths and other changes, On my last update the client break to malfunction on a lot of freezed computers that have the client installed on non default path, a little problem with the updaterhelper.

Have you try to delete the token.dat on each boot from each S.O.?

Something drastic is configure linux (maybe from udev or another way before de FOGService boot) to change the mac address and register the computer as another diferent?.

First excuse me to link this post to you, but I think that is important, and for me VERY Important

I have an enviroment with 16500 computers, and 60 Storage Nodes growing, with location plugin. FOG 1.5.6
And I have this statistics:
hosts table: 16.500 records
hostMAC: 2800
Tabla snapins: 210
Tabla snapinAssoc: 45.403
Tabla snapinGroupAssoc: 15390

This is verified on FOG Version 1.5.6 and FOG Version 1.5.7

The problem:
The following list of pages loads two slow, a few minutes:

host management -> Host general
host management -> Basic Task -> Deploy
host management -> Basic Task -> Snapins
Group management -> Snapins
Group management -> Basic Task -> Deploy
Group management -> Basic Task -> Snapins
Snapin management -> List All Snapins
... at least

First i think that was a database stress workload problem.
Second Speaking with @Fernando-Gietz we think that was a filter problem.
But as I was unable to create a filter that works.
Then reading the code a bit more i found that the problem is on the line 1297 on fog/lib/router/route.class.php
" ‘storagegroupname’ => $class->getStorageGroup()->get(‘name’)"

if you change the lines
$class->get(),
array(
‘storagegroupname’ => $class->getStorageGroup()->get(‘name’)
)
by
$class->get()

The pages goes much more faster.

I have commented that line and seems that all works correctly with our operations. But maybe is better than someone that knows what are doing take a look about that and can find a “Correct Solution”.

Free to request more explanations.

Hehehe i Verified it again!!! @Quazz Task Deploy info on database is updated during progress on deploying at least, a few computers is not problem, but with 16500 and 13 techies working like slaves this can be a cause of database’s stress.

At least taskPercentText, taskDataCopied, taskTimeRemaining, taskTimeElapsed, taskBPM on task table is updated during partition deploy.

I think that this info can help to improve this great solution.

Hi, @Sebastian-Roth .

I’m here again, I don’t know where to put this thread, because this is not properly a bug.

First at all, I have currently 16.500 computers registered on my fog system, with 60 StorageNodes, and growing, located on different buildings on different towns, we are 13 techies.

I need to notify than the continuous writtings on the database, to report the clonation progress, causes a lot of not needed stress on the database, maybe is a good idea to change the notification system, to reduce stress and make the system more scalable.

Two ideas:
Easier: Notification on 33%, 66%, 90%, 100%.
Best: Get out of the database that informatión and store only the clonation data need by the history.

Some options.

1º Use a snapin pack including the executable.
2º Put it in a ftp server and use a cmd ftp client to download it. (You can use the fog server/node as ftp and the built-in ftp client)

This two solutions works!!!

@Wayne-Workman I’m using local standard database and i see that problem, but i have identified the undesired hosts as iPXE menu registered hosts.

@Sebastian-Roth Ok no problem, it’s better for me. I learn english and i get help, it’s a great reward, hehehe

Thank’s to all the team for your time and efforts. if you want I can spend some time to find it and report the thread, to you.

It’s not important for me because I don’t use that feature. I’m only trying to help telling my experiences. Maybe, after i resolve some works i can offer me to help in another ways.

@Tom-Elliott @Sebastian-Roth

I’m testing on my home environment the 1.5.7.713 (1.6), and i need to apply my “little database”, to see how it works, but at the first eye, that is a perfect solution for my request. I can go to “fog settings” without wait for the node list and i can I have a direct access to home page on FOG Configuration.

I want to add something, if it’s possible that, when you have communication problems with nodes they will be printed in red instead of remove it from list. Maybe it’s implemented now?..

@Sebastian-Roth uhmmm, I try with another words.

When I create a group, selecting some computers on host management, fog adds at least some computers registered from iPXE boot menu.
If I select some computers, from host management, and add them to a existing group, fog adds, at least, some computers registered from iPXE boot menu.

I don’t know if some is equal to all

I delete them and reregistered from Web UI and they dont be added anymore. I thinked that was a database error, and I do not investigate the problem for that reason. How we don’t usually work’s “on place”, we usually have that menu disabled and I don’t see this effect anymore.

@Sebastian-Roth

Quick Host Registration and Inventory
and
Perform Full Host Registration and Inventory

iPXE Grub Menu Options.

I think that is missing lan driver, because it don’t try the udhcpd requests, but better report the kernel version to get response.

If you can’t get the kernel version download a 4.12.x or upper, assign it to the computer and try if it works, if it works you can set it as default on fog settings page.

@ITCC I’have the same problem but the pc’s added are ever the same and i discover that was registered via grub

@george1421 ok i Don’t Think about that. I Will do the corrections tomorrow. What about the rest of mounts?

I mount /images on one disk and /images/dev on another disk and mysql database dir on a ssd and mysql temp dir on the shared memory (/dev/shm) using fstab and adding a custom settings to mysql systemd execution. On tjis way i dont touch fog basic system settings.

If you are interested tellme and i try to explain it carefully with more details.

Hi @chaddarnold @Quazz

1º.- As @Quazz said, use the Reset Encryption Data Button for the host/group in UI.
2º.- Delete the token.dat file on the Fog Client folder directory if it exists.
3º.- If you install Fog Client on the image be sure to image the computer with that file deleted, better if you automate the client installation on the first boot.

Make your install script with this recommended commands:

msiexec /i "C:\NewClientInstaller" /quiet USETRAY="0" HTTPS="0" WEBADDRESS="YourFOGAddress" WEBROOT="/fog" ROOTLOG="1"
sc.exe config FOGService start=delayed-auto
sc.exe failure FOGService actions= restart/60000/restart/60000/restart/ reset= 120
net start FOGService

@Tom-Elliott yeah i mean that. It’s a good idea but i Think that is a good idea too to have the current Page too as a sublink on fog settings. Changing the background color instead of erasing when the node is offline. To have a panorama of the system. I Dong unos if i explain correctly

I have an environment with 15500 clients on many diferent sites and i’m very interested in a discusion or topic like this.

Try configuring the servicio with this:

sc.exe config FOGService start=delayed-auto
sc.exe failure FOGService actions= restart/60000/restart/60000/restart/ reset= 120.

It work’s to save me from stopping Fogservice errors.
