OK. I still did not get it to work. But in the meantime I simplified the setup
so that we only have two subnets divided only by the head node. I was hoping
that somebody could give me some hints how I can get this to work, so here is
a detailed description of our setup:
We have a computing cluster running myrinet and all this nodes are on a
private subnet, in the middle there is our headnode with two ethernet devices
one connected to the myrinet guys and the other one to our labmachines. This
second ethernet device is now also on the same subnet as the labmachines. I
was hoping that we won't need the multicast setup anymore. Currently the
headnode is exporting a nfs filesystem, but we want to switch it to gfs.
I head the multihome setup from the wiki working, but dlm does not support it,
so I canceled that.
We can not use ethernet bonding (i guess), because than the nodes would not
find the headnode anymore as it would then be on a different subnet.
I thought this is like a standard setup, but it seems to be strange. I wish
there was more documentation.
Thanks for any hints.
