FOG 1.5.6 Multicast problem?!

[Sebastian Roth]

@kratkale Seems like it does not find the right network interface. Please double check the FOG config settings in the web UI for the multicast network interface setting.

As well, which Linux OS do you use?

[kratkale]

@Sebastian-Roth
it is a brand new installed debian
root@FOG:/images# cat /proc/version
Linux version 4.9.0-9-amd64 (debian-kernel@lists.debian.org) (gcc version 6.3.0 20170516 (Debian 6.3.0-18+deb9u1) ) #1 SMP Debian 4.9.168-1 (2019-04-12)

normal deployment of single computers works very well!

@kratkale I tested on Debian as well, strange. Will take a look at the code when I get home in half an hour.

[Sebastian Roth]

@kratkale Ahhhh, just remembered that we had a similar issue, see here https://github.com/FOGProject/fogproject/issues/268

We ought to find a better solution to this…

@Sebastian-Roth
This aproach is cousing a boot loop " Unable to locate image store …"

/var/www/html/fog/lib/fog/fogbase.class.php, jump to line 2226 and comment the first three lines of the getIPAddress() function. Make it look like this:

    /**
     * Get IP Addresses of the server.
     *
     * @return array
     */
    protected static function getIPAddress()
    {
//        if (count(self::$ips) > 0) {
//            return self::$ips;
//        }
        $output = array();
        exec(
            "/sbin/ip -4 addr | awk -F'[ /]+' '/global/ {print $3}'",
            $IPs,
            $retVal
        );

@kratkale Let’s try to take a new approach to this. Please edit /lib/systemd/system/FOGMulticastManager.service, goto line 18 that looks like this:

After=syslog.target network.target mysql.service

Change it to look like this:

After=syslog.target network-online.target mysql.service

Then reboot your FOG server and check /var/log/fog/fogmulticast.log again.

As well you might run systemd-analyze plot > systemd-deps.svg and upload that SVG graphics file to a file share and post a link here. On my Debian test VM it looks like this:

The FOG* services start late on that test system (latest Debian in virtualbox VM) anyway and that is without the above mentioned change. Would be interesting to see if that looks different on your hardware server. Possibly the network interface card on your hardware just takes a little longer…

Now the addrees is here:

@kratkale Then schedule another multicast task and see if it’s working. I guess we are on the right way with this.

Earlier on you said:

This aproach is cousing a boot loop " Unable to locate image store …"

Where did you see this message?

[kratkale]

@Sebastian-Roth
just the messeage you see in the pic. I’ve still this problem!

There are no images anymore???
I ve to check the mounting …

[kratkale]

@Sebastian-Roth
ok - I lost the image I’ve done new on this configuration.

The old images (importet with csv file) are still available in Web GUI

in /images I can find all the folder: old an new …

There was a mistake in the fstab file - so the hdd was not mounted

[kratkale]

ok I took now an old image
it is working but:
-) Erasing current MBR/GPT Tables takes a looooooooooooooooong time
-) Cloning works much faster 12,7GB/min instead of 8GB/min
no mistakes with the old image

[Sebastian Roth]

@kratkale said in FOG 1.5.6 Multicast problem?!:

Erasing current MBR/GPT Tables takes a looooooooooooooooong time

You have the older init files (1.5.4) still in place I am fairly sure. Hope you still have a copy of the 1.5.6 inits. If not, download here.

So to sum things up, systemd might bring up network interfaces too late and we need to wait for that! I will push a fix for that soon.

[kratkale]

@Sebastian-Roth
I can confirm it is working with 1.5.6 and 1.5.4!

I’ve done a big mistake!
I was booting form the old system SSD connected via USB. So the changes where applied to 1.5.4 not to 1.5.6. That was why the hdd was not mounted; why I lost the image …

Now I’ve another Problem.
Before rebooting I get the messeage:
“A warning has been detected!”
Failed to set disk guid …
I’ll open a new task

[Sebastian Roth]

@kratkale Ok thanks for the update. So I will mark this solved again. Will push the systemd fixes to dev-branch soon.
