@Sebastian-Roth
Hi Sebastien,
I’m using FOG 1.5.5 with init files included with it.
As suggested in a previous post (https://forums.fogproject.org/post/123192), I backed up init files stored in /var/www/html/fog/service/ipxe/ and put instead the last ini files.
I had the behavior described : shrinking OK but FTP error then. I put back the 1.5.5 ini files and then everything worked back. It’s may be just a coincidence I can try again.
So I found by myself.
The issue was the /etc/exports that was still referencing original /images folder instead of /cloning/fog
So this part is solved.
I’ll reply to myself.
finally I found that image was partially copied to storing folder.
So yes no images was found !!
I just had to re-upload a backup to solve this issue.
sorry for the disturbing.
Hi,
I have a FOG server 1.5.10 on an ubuntu 22.04.
We can dump and load files on/from this server without any issue, but since friday we try to load an old image (not loaded for 2 years now) and we have this message :
no image file(s) found that would match the partition(s) to restored etc …
In image file folder this what we have in the config files :
fstypes:
/dev/sda1 ntfs
fixed_size_partitions :
empty
partitions:
label: dos
label-id: 0x33799606
device: /dev/sda
unit: sectors
/dev/sda1 : start= 2048, size= 1000212992, type=7, bootable
Minimum partitions :
cat d1.minimum.partitions
label: dos
label-id: 0x33799606
device: /dev/sda
unit: sectors
/dev/sda1 : start= 2048, size= 402749760, type=7, bootable
We tried to load the file using all image type setting in web interface of fog server.
This never changed the error message we had except for RAW where this time the machine reboot without giving any visible error message before image load of course.
We tried to load it on several physical machines with disks from 500GB to 2TB.
We tried on VM with 1TB of disk and it did not help either.
I take any help or advice in this case.

@Joe-Gill
I work in particular environment : a school.
All we install is use for a very short period (not more than 2 weeks) , So I don’t need to SysPrep for instance.
Nearly the same for our software that are pre-installed in our images as they usually are free and for those which are under trial license it depends from a software to another.
So I’m not using FOG in a “REAL” production environment.
HI @Tom-Elliott,
Ok thanks for you anwers.
Is it possible to check for replication may be once a day @ night and not 24/24-7/7 as it going right now ?
Proc.
FIrst let set the scene :
I have 2 FOGs server : 1 on main site 1 other on branch site.
Both are ubutnu 22.04
Each fog server storage node are masters on their site.
On main site, branch storage node has been added to default group but not as master. This way we should have only 1 way replication.
I can see on main site FOG server dashboard both storages.
This strange behaviour appear :
On main site FOG server (also detaining master storage node) I detected massive bandwidth utilisation. (input and output)
Regarding the input this do not surprise me as master should replicate images not already sync images on branch site.
Then regarding the input I don’t really understand as the master should no get anything from the branch other than images list.
So then I tail the replicator log and this is what I have :
[06-21-24 9:00:34 am] * Starting Image Replication.
[06-21-24 9:00:34 am] * We are group ID: 1. We are group name: default
[06-21-24 9:00:34 am] * We are node ID: 1. We are node name: DefaultMember
[06-21-24 9:00:34 am] * Attempting to perform Group -> Group image replication.
[06-21-24 9:00:34 am] | Replicating postdownloadscripts
[06-21-24 9:00:34 am] * Found Image to transfer to 1 node
[06-21-24 9:00:34 am] | File Name: postdownloadscripts
[06-21-24 9:00:35 am] # postdownloadscripts: No need to sync fog.postdownload (FOG-01)
[06-21-24 9:00:36 am] * All files synced for this item.
[06-21-24 9:00:36 am] | Replicating postinitscripts

[06-21-24 9:00:37 am] # dev/postinitscripts: No need to sync fog.postinit (FOG-01)
[06-21-24 9:00:37 am] * All files synced for this item.
[06-21-24 9:00:37 am] * Not syncing Image between groups

[06-21-24 9:00:37 am] | There are no other members to sync to.
[06-21-24 9:00:37 am] * Not syncing Image between groups
....
and it does this for all images we host on master node
....
[06-21-24 9:00:40 am] | Image Name: Android Studio
[06-21-24 9:00:42 am] # Android Studio: No need to sync d1.fixed_size_partitions (FOG-01)
[06-21-24 9:00:43 am] # Android Studio: No need to sync d1.mbr (FOG-01)
[06-21-24 9:00:45 am] # Android Studio: No need to sync d1.minimum.partitions (FOG-01)
[06-21-24 9:00:45 am] # Android Studio: No need to sync d1.original.fstypes (FOG-01)
[06-21-24 9:00:45 am] # Android Studio: No need to sync d1.original.swapuuids (FOG-01)
[06-21-24 9:00:46 am] # Android Studio: No need to sync d1.partitions (FOG-01)
[06-21-24 9:00:48 am] # Android Studio: No need to sync d1p1.img (FOG-01)
[06-21-24 9:00:50 am] # Android Studio: No need to sync d1p2.img (FOG-01)
[06-21-24 9:00:50 am] * All files synced for this item.
...
and it does this for all images we host on master node and loop to the first part endlessly.
In about 1 hour I get near a 10000 lines log file for about only 90 images where I expected to have less than 1000.
Is it normal it loops over and over ?
This is how I configured the branch storage node on main server :
Many thanks by advance for any help.
Hi,
I’m using FOG for years now (April 2019) and nothing changed since.
We are imaging, W10, W11, WServers 2019 (I don’t remember if we do more recent ones), a bunch a Linux distribs. (All bios and uefi)
And we did not changed anything since 2019.
Oh, I did not saw the second part of your message regarding software. for this I don’t know
I quickly read about your issue, could this be related with your problem ? :
https://forums.fogproject.org/topic/10006/ubuntu-is-fog-s-enemy?page=1
@Tom-Elliott said in Multicast timeout:
You created a table in FOG called hostsIP?
Yes, in our environment hosts, have ip reservations and I did not found in FOG tables last used ip by hosts (may be I missed something) so I created a table associating ip to hosts names.
@Tom-Elliott said in Multicast timeout:
Note: This isn’t a bad thing, I’m just trying to reference the information.
No worries.
@Tom-Elliott said in Multicast timeout:
The way I understand this, you’re looking at the mutlicastSessions table, getting a group, and getting the name of the hosts.
@Tom-Elliott said in Multicast timeout:
You’re at least aware of the IPs which most others will not be, but just trying to think this through.
I searched for a more elegant way to get hosts ip and which could be universal, but the lack of time lead me to this rude behaviour 
But if someone has an idea on how to do it I would be very please to update this.
To be honest I thought to modify more the init.xz to populate automatically the hostsIP table when it loads but I have a working solution and it’s not even a priority for us but something more comfortable, if I had spent more time on this, someone would have come to break my fingers
Sorry for the long post.
Hi,
I deal with my problem, now crashed multicast clients can be stopped and relaunch automatically once session has finished.
The fact that any machine in our environnement use IP reservation made things easy.
I managed only crashed clients, but it would be easy to add a WOL or a client restart but I consider that if WOL or Client restart has not worked first there no reason it works better 1h later without any intervention.
If someone is interested by such a feature here is the script. It could be trigger every hour, this way whenever the multicast session is finished the client is reinstalled.
I used it in test environnement for now, so there could be some issues. I you find some or have any idea to make it better please share and I’ll correct it :

Thanks Tom !!
Sorry for this POST I feel so ashamed by this noob mistake.
So it’s solved!
