The problem was the IGMP Snooping as you suspected. Thank you for your help.

Hi everyone,

I have three rooms, each containing several identical computers. These rooms are all on the same VLAN, connected across multiple switches without any router in between. Multicasting works successfully in one of the rooms where I have two test computers. However, in the other rooms with more computers, the multicast starts fine but drops to zero speed at around 80% completion, causing FOG to disconnect the clients. Our IT department informed me that IGMP snooping is enabled on the switches. Does anyone have suggestions on what I should do?

Thanks!

Here are the multicasting logs from FOG:

@george1421

The problem was the IGMP Snooping as you suspected. Thank you for your help.

@TaTa

Thank you for your reply. I didn’t try your solution but after IGMP Snooping was configured on the VLAN, the multicasting worked immediately.

I left all the Fog multicasting settings as default.

@george1421 Thank you for the clarification and your good advice. I will look into it further.

I’m having trouble with multicasting and suspect it’s because there are several switches between the Fog server and the host computer, even though they’re all on the same VLAN. After checking the documentation, I’m still unsure which port numbers need to be allowed for multicasting to work correctly. The Web UI indicates that port 63100 is the default for broadcasting, and Udpcast uses port 9000 and port 9001.

I’m not an expert in networking, so I would appreciate it if someone could tell me if I need to ask our networking team to open specific ports on that VLAN for multicasting. Any other advice would also be very helpful. Thank you!

Hello,

My Fog server is behind several switches but is on the same VLAN as my Host computers. The Multicast starts and continues until the Partclone page appears and nothing happens from there. I read another post that indicated that the multi-switch environment must be the problem but no solution was offered. Does anyone know how I should approach troubleshooting?

Process stuck here.

@Tom-Elliott,

Thank you for clarifying the situation. That makes sense now that you mention it.

One issue is still puzzling me. When I’m debugging, I notice that the “hd” parameter is always passed as /dev/nvme0n1 even when I’ve configured it as /dev/nvme1n1 in the iPXE menu parameters. I understand that NVMe names might not remain consistent across boots, but shouldn’t the hd parameter at least reflect the correct path set in the iPXE menu?

Another question is: how difficult is it to create an interactive deployment process where users can choose the disk for image deployment after the boot? Given that PCI naming persists after boot, can FOG simply use the variable set by the user as the target disk? Are there any limitations that would prevent implementing such a feature?

I’m encountering an issue with my iPXE menu configuration when specifying the target disk for FOG image deployment. It works smoothly on computers with a traditional hard disk and Legacy BIOS. However, the same setup fails on machines equipped with NVMe SSDs and running UEFI. I suspect that either the hd parameter isn’t recognized in the case of SSDs or there’s an underlying UEFI compatibility issue.

I’ve been struggling to resolve this for quite some time now and would greatly appreciate any assistance.

Here’s the configuration for computers with HDD:

kernel bzImage loglevel=4 initrd=init.xz root=/dev/ram0 rw ramdisk_size=275000 web=http://192.168.1.1/fog/ consoleblank=0 rootfstype=ext4 nvme_core.default_ps_max_latency_us=0 mac= ftp=192.168.1.1 storage=192.168.1.1:/images/ storageip=192.168.1.1 osid=9 irqpoll chkdsk=0 img=Peruswin10 imgType=n imgPartitionType=all imgid=4 imgFormat=5 capone=1 type=down hd=/dev/sdb isdebug=yes
imgfetch init.xz
boot

And for the target computers with UEFI and SSD:

kernel bzImage loglevel=4 initrd=init.xz root=/dev/ram0 rw ramdisk_size=275000 web=http://192.168.1.1/fog/ consoleblank=0 rootfstype=ext4 nvme_core.default_ps_max_latency_us=0 mac= ftp=192.168.1.1 storage=192.168.1.1:/images/ storageip=192.168.1.1 osid=9 irqpoll chkdsk=0 img=Windows10 imgType=n imgPartitionType=all imgid=5 imgFormat=5 capone=1 type=down hd=/dev/nvme1n1 isdebug=yes
imgfetch init.xz
boot

@sami-blackkite

I’m not an expert on this but I have been successfully capturing my images from nvme drives.

Do you set your Image Type as Single Disk?

PS: I changed BOOT EXIT TYPE and EFI BOOT EXIT TYPE and the rEFInd menu appeared and the Windows was booted.

Just curious to know if that fixed the situation or renaming the files which I mentioned before.
