Tom Elliott

I’ve already found and fixed this issue, just putting through a few last minute tests.

Tom Elliott

Should be fixed in latest. Please update and let me know. Thank you,

@Tom-Elliott
I could boot the machine now, but it stuck at this screen

@dvchuyen Take a look at these:

@Wayne-Workman
I am checking the topics. However, Multicast worked fine before until I update FOG.

Thanks,

Tom Elliott

@dvchuyen When did you update and from what to what did you update? I ask because that was kind of unmentioned in the post generally speaking.

I tested multicast and am able to verify that it works. The other times I see the issue as in your picture it tends to be the interface UDP-Cast is trying to use is incorrect. You can provide the /opt/fog/log/multicast.log file as well to help us help you more appropriately.

I remember I worked in v6566 (I could not remember exactly). I updated through SVN. . I also updated to last version (7228), and same thing happen. Nothing changed with network infrastructure, my FOG is Centos7 installed on ESXi, I created a test VM with same network and it does not work either. I also rebooted the FOG server.
Here is the multicast.log

@dvchuyen said in could not pxe boot (input/output error) when do multicast:

/usr/local/sbin/udp-sender --interface eno16777984

How many nodes to you have?

dvchuyen

This post is deleted!

dvchuyen

@Tom-Elliott
I have only 1 node. Images are stored in Fog server. Server has 2 NICs: 1 for manage console, and 1 for imaging

dvchuyen

It seems that the multicast job is cancel automatically. I set timeout 10 minutes

Tom Elliott

@dvchuyen And interface eno167777984 is connected to the network expecting handle the Multicast traffic? The fact that it appears to cancel directly after starting leads me to believe the eno16777984 nic is not the nic that’s expected to be running. Either the interface itself doesn’t exist or it doesn’t have an address associated to it when you’re trying to run the multicast task.

@dvchuyen and that’s about how most of us feel when Tom posts to a thread.

Update to latest verion, restart the server, now the task is not cancelled but It still stuck at Starting to restore image.

@dvchuyen There are commands in here to clear the tables related to multicast: https://wiki.fogproject.org/wiki/index.php?title=Troubleshoot_Downloading_-_Multicast

dvchuyen

@Wayne-Workman Yes, I already cleared the tables then re-runed the installer,
