@Yann Sagon:
This is a good point. I didn't notice this. I'm new to this particular
system. Everything installed, configured etc. was already there when i
got into it. I'll keep that in mind, because i've got to discuss the
upgrade with the group. Maybe i should set it up from the beginning then.
@John Desantis
I checked Nodenames and their proper IP adresses. The /etc/hosts
contains the correct IP Adress with the full DNS aswell as the nodename
e.g. "node01". "ping node01" works.
@Trevor Cooper
The munge daemon is reporting no errors in munged.log, also all nodes
are syncing times with one and the same NTP Server. Nevertheless a
manual check showed the exact same time on every node.
@Moe Jette
I already went through the "Slurm is not responding" points.
Unfortunately none helped.
Thanks everybody who answered until now!
