Description

Hi everybody,

we have had 2 interfaces for our fog-server before. Call them inner and outer Interface. The fog-server listened to the inner interface before and now we decided to make it one network, so the inner interface isn’t used anymore. So we changed the IP-Address of the fog server.
Now everything seems to work fine with the outer interface (deploy one client, dhcpd, etc.) except, that we cannot deploy more than one client with multicast anymore.
Both Testclients stop with this message:

Partclone v0.2.89 http://partclone.org
Starting to restore system image (-) to device (/dev/sda1)
Note: Storage Location 10.203.8.21/images. Image Name M2_Win7

Storage location is correct.

Strange thing is, why a normal deploy works correctly, but not multicast.

First I thought, that it was maybe because of the different switch the outer interface was on now, but then I used the same switch as before (the switch, where the inner interface was connected before - clients are also on this switch), and it still doesn’t work.

What I can see in daemon.log:

So obviously the clients mount the image share.

Is there another logfile, where I can get more information?

Thanx,
Rainer

Ok … reran the install-script again, and now it seems to work.
Although it is very slow. Before we needed 15 minutes for the clients, now 45 are estimated.

Edit: Maybe the other switch only can do 100 MBit/s. Would explain, why it is so slow. Clients do 1,5 GB/min at the moment.

@Tywyn Probably there was the multicast interface setting (FOG web GUI -> FOG Settings) still wrong.

Not sure about the performance issue now. Please check layer one (hardware, switch) first.
